Background on the Three Collas

Ancient Irish tradition tells us that Airghialla (or Oriel) was a territory in northern Ireland founded by the three Collas about the 4th century of the Christian Era, and inhabited by their descendants in later centuries. As is the case with much of Irish saga prior to the 6th century keep in mind the line between myth and history is unclear. The term Airgialla is translated as 'those who give hostages', alluding to a subordinate status of the various groups inhabiting the area. Contemporary writers, e.g. O'Rahilly and Byrne, suggest the three Collas are mere doublets of the three sons of Niall Noigiallach who conquered portions of early Ulster, their names being Eogan, Conall and Enda.

The three sons of Eochaid Duibhlein and Aileach, a daughter of the King of Alba, all bore the name of Colla - Colla Uais, Colla Meann and Colla da Crich (Fochríth). The designation Colla, meaning strong man, was "imposed on them for rebelling," their original names being Cairsall, Aodh and Muredach, respectively. The three Collas went to Scotland to obtain the assistance of their kindred to place Colla Uais on the Irish throne, and with their help placed him there, but he was compelled to give way to a relative, Muredach Tirech, who had a better title to the sovereignty.

The three Collas made war with the High King of Ireland, Fiachadh, and overthrew and killed him in order to sieze the Kingship for Colla Uais, which he enjoyed for four years. Muiredach Tirech, the son of the slain king Fiachadh, overthrew the three Collas and their followers. About the year 327 the three Collas were exiled to Alba (Scotland). They were received into their maternal grandfather's court, the court of the Scots and Picts.

  • The Irish Annals record for the year of our Lord 322 cite, "Fiacha(dh) Sraibhtine, after having been thirty seven years as king over Ireland, was slain by the Collas, in the battle of Dubhchomar, in Crioch Rois, in Breagh."
  • The annals further record for the year 323, "The first year of Colla Uais, son of Eochaidh Doimhlen, as king over Ireland."
  • For the year 327 the annals state, "The fourth year of Colla Uais, in the sovereignty of Ireland, when Muireadhach Tireach expelled him and his brothers into Alba (Scotland) with three hundred along with them."
  • The annals continue for the same year, "At the end of this year the three Collas came (back) to Ireland; and there lived not of their forces but thrice nine persons only. They then went to Muireadhach, having been instructed by a druid. And they scolded at him, and expressed evil words, that he might kill them, and that it might be on him the curse of the finghal should alight. As he did not oppose them, they tarried with him, and were faithful to him."

    "It was when Muiredeach Tireach, grandson of Carbri of the Liffey, was High King of Ireland, that Ulster was despoiled and broken by his nephews, the three Collas, who, on the ruins of the old kingdom of Uladh, founded a new kingdom - of Oirgialla (Oriel) which was henceforth for nearly a thousand years to play an important part in the history of Northern Ireland."
    "The Collas first went to their kin in Connaught [King Muiredeach] and there gathered a great army for the invasion of Ulster. On the plain of Farney in Monaghan they met the Ulstermen under their king, Fergus, and on seven successive days broke battle upon them, finally slaying Fergus and putting the Ultach (Ulstermen) to complete rout. Of the conquered portion of Ulster, from Louth in the south to Derry in the north, and from Loch Neagh to Loch Erne, the Collas made themselves the new kingdom of Oirgialla (Oriel)."
    [source: http://www.ireland.org/irl_hist/hist11.htm]

    The Irish Annals record for the year of our Lord 331, "The battle of Achadh Leithdheirg, in Fearnmhagh (Farney), was fought by the three Collas against the Ulstermen, in which fell Fearghus Fogha, son of Fraechar Foirtriun, the last king of Ulster, who resided at Eamhain. They afterwards burned Eamhain [Macha], and the Ulstermen did not dwell therein since. They also took from the Ulstermen that part of the province extending from the Righe and Loch nEathach (Neagh) westwards. Colla Meann fell in this battle. [source: http://www.ucc.ie/celt/published/T100005A/text030.html]

    Geoffrey Keating adds in his History that "On that occasion, the Collas wrested the following territority from the Ultonians [men of Ulster], namely, Modharnuigh, Ui Criomthainn, and Ui Mac Uais. Colla Meann took possession of Modharnuigh, and Colla da Chrioch of Ui Criomhthainn, and Colla Uais of Ui Mac Uais. And Muireadhach Tireach fell by Caolbhaidh son of Cronn Badhraoi."

    The descended Groups and Families of the Three Collas

    Colla-da-Chrioch - The first king of Arghialla would be Colla-da-Chrioch (aka Colla Fochríth).
    The Book of Ballymote cites Síl Colla Focrích; of this stock are: Airthera, Rigradh Dartraighe Coindinse, Ui Meth, Fir Fernmuighe, Fir Manach, Fir Lemna, Síl Duibtiri, Ui Briuin Archoill, Fir Roiss, Ui Maine, Fir Dubhshlat, Ui Cennfhada, Ui mic Brocc, Ui Echach bega, Ui Echach móra, Ui Dortaind, Ui Níalláin, Ui Conaill, Ui Bresail of Macha and of Mughdorn, Ui Cremthaind, and Ui Luain, with relatives.
    Colla Focrích (Colla-da-Chrioch) had four sons noted here; Imchad, Findchad, Rochaid, Fiachra Cassán.
  • From Imchad came Muiredach Méth, a quo Uí Méith. According to early genealogies, the Uí Maine Connacht are also descended from Imchad.
  • From Rochad descended the Cenél Rochada, that is the Fernmuigi and Síl Daim Argait and Uí Briúin ar Chaill and Uí Labrada and Dál n-Uaich (Oaich) and Uí Chremthainn and Uí Meic Brócc and Uí Tuathail.
  • From Fiachra Cassán descended the Síl Fiachra Cassán, that is the Airthir of Ard Macha and Uí Breasail and Uí Nialláin and Uí Dorthain and Uí Eochada and Uí Cruind and Uí Trena.

    Colla Uais had sons named Eachach and Ercc. From Colla Uais descended the Uí Meic Uais and Uí Tuirtri and Uí Cormaic and Uí Dáire and Ui Fiacrach Arda Sratha and Cenél Meic Cárthind and Cenél mBecce and Cenél Raithne and Cenél n-Erchoil.
    The Book of Ballymote cites Síl Colla Uais, i.e. Ui Mac Uais, Ui Tuírtre, Fir Luirg, Ui Fiacrach Arda Sratha, Ui Mic Cairthaind, Fir na tri leth, Fir Leitreach, Fir Lugaidh, Fir in Muighe, Ui Tabarna, Fir in Chláir, Ui Mic Cairthaind of L. Febail, and the Fir ili (Fir Li?)

    Colla Menn had sons named Mennit Chruthnech and Mugdorn Dub di Ultaib. From Colla Meann descended the Mughdorna and the Dál Mennat.

    From Colla-da-Chrioch are claimed to descend some of these noble families of Ulster and elsewhere - Boylan, Brassil, Cahil, Callaghan, Carbery, Carey, Carroll, Cassidy, Conan, O'Connor, Corrigan, Cosgrave, Devine, O'Donnell, Donnelly, Duffy, Dwyer, Fogarty, Garvey, Gavin, Hanlon, Hart, Higgins, Hollgan, Kelly, Kennedy, Keogh, Lane, Larkin, Leahy, Lynch, MacCabe, MacDaniel, MacKenna, MacMahan, MacManus, Madigan, Madden, Maguire, Malone, Mitchell, Mooney, Muldoon, Norton, Orr, Traynor, Tully, etc.


    Airghialla, the Tribes of the Three Collas

    The Airghialla were a loose federation of tuath, largely located in the modern province of Ulster. Their territory, depending on timeframe, included much of what includes the modern counties of Monaghan, Armagh and Fermanagh. In addition, other places where Arghialla groups have been noted included areas within the modern counties of Tyrone, Cavan, Meath, Westmeath, Louth, and Derry. The Airghialla federation included Uí Cremthainn, Uí Méith, Uí Tuirtre, Uí Meic Uais, Uí Fiachra Ard Sratha, Mughdorna, Uí Meic Cáirthinn, Airthir, Fernmhaighe, and Fir Lí, among other terms descriptive of tribal groupings and territories.
    The Book of Fenagh states the sub-territories of Airgialla were: Ui Nialláin (Oneilland baronies, co. Armagh.); Ui Bresail (now in the baronies of Oneilland); Ui Echach (baronies of Iveagh, co. Down); Ui Meith [Macha] (parishes of of Tullycorbet, Kilmore and Tehallan. co. Monaghan.); Ui Tortain (around Ardbraccan, co. Meath); Ui Briuin Archaill (in the barony of Dungannon, co. Tyrone); Trí Tuatha (here comprising Fir Lemna, Ui Cremthainne and Síl Dubthir of Lct.); Dartraige, alias Dartraige Coininnsi (barony of Dartry, c. Monaghan.); Fera Manach (Fermanagh), Fernmag (barony of Farney, co. Monaghan.); Mugdorn and Ross (Cremorne with the parish of Carrickmacross, and parish of Clonany, co. Monaghan., and adjoining parts of Louth and Meath undefined).
    Noted chiefs of Airghialla included Ua Laidhgnén (O'Leighnin?), Ua Éiccnigh (O'Heany or Hegney), Ua Cerbhaill (O'Carroll), Ua Baígelláin (O'Boylan), Ua Anluain (O'Hanlon), Mac Mathgamna (MacMahon), among others.

    A steady push by the Cenél nEógain in the 7th and 8th centuries reduced the size of the Aighiallan federation as the people of northern Airghialla came to be treated as sub-kingdoms of the Cenél nEógain. During a similar period the southern branches of the Airghialla came under the dominion of the southern Uí Néill kingdoms of Mide and Brega. By the 9th century Airgialla proper, as a political entity, was practically confined to the modern counties Armagh, Monaghan, Fermanagh, and part of Louth, with the Uí Thuirtri kingdom in east Tyrone in process of being absorbed into the Cenél nEógain over-kingdom of Ailech.

    In the 12th century the Ua Cearbhaill (O'Carroll) were prominent among the kings of Arghialla. By the 13th century the family of MacMahon (MacMathghamhna) held the superior authority with the title king of Oirghialla (Oriel), by that time a much reduced sub-kingdom.

    As chiefs, or royal heirs, of the Airghialla (Orghialla or Oriel) area, the Irish Annals cite:


    Uí Cremthainn - the territory about eastern Co. Fermanagh and northern Co. Monaghan. The early genealogies state the Uí Chremthaind were descendants of one of the three Collas, i.e. Colla Fochríth. An early genealogy shows descent from Crimthann liath (from whom Uí Crimthainn), son of Fiac, a son of Deach Dorn, son of Rochad, son of Colla da Crich (aka Colla Fochríth). In effect, the Uí Cremthainn consisted of multiple groups, and were considered part of the overall Airghialla confederation.
    Some of the prominent descendants from Crimthann liath included, among others, the Clann Nadsluaig of modern co. Monaghan (O'Carroll, McMahon, ...), the Clann Lugain of co. Fermanagh (Maguire, McManus, ...), the Clann Ceallaigh (MacDonnell, ...) of co. Monaghan, and the Sil nDamine of co. Fermanagh (Mael Ruanaigh, ...). Each of these were descended through Cairpre Dam Argait, a grandson of Crimthann liath.
    Three of the sons of Cairpre are noted here, that is, Cormac (a quo clann Cormaic, clann Lugain, Muintir Pheodachain, Muintir Caeman, clann Fergaile), Daimine (a quo Sil nDamine, Síl Tuathail an Tuaiscirt, clann Cellaig, Mac Maolruanaig, et al) and Nadsluag (a quo clann Nadsluaig, Ua Cearbhaill, Ua Mathgamna, et al). From clann Lugain the prominent families of Ua hÉicnigh, Mag Uidhir and Mac Maghnuis are noted, among others.

    In the late 10th and early 11th centuries the sept of Mael Ruanaigh are noted in the annals as kings of Cremthainn, although this appears to be a reference to the district of Cremthann in Connacht. The Mac Murchadha family were prominent as lords of Truagh in northern Monaghan in the barony of Trough, before being overshadowed by the MacKenna(n) sept, of the southern Ui Neill. Included among the prominent Aighialla families were the Ua Baigeallain (O Boylan) of Sil Maeluidir in the area of Dartraige (Darty, western co. Monaghan).

    An early genealogy of Sil Daimine:   (Rawlinson)
    Daimíne, son of Cairpre Dam Argait, son of Eocho, son of Crimthann Lethan, son of Fiacc, son of Daig Duirn, son of Rochaid, son of Colla Fochríth (da-Chrioch).

    An early genealogy for Clann Nadsluaigh:   (Rawlinson)
    Nadsluaigh, son of Cairpre Dam Argait, son of Eocho, son of Crimthann Lethan, son of Fiacc, son of Daig Duirn, son of Rochaid, son of Colla Fochríth (da-Chrioch).

    An early genealogy for Clann Lugain:   (Rawlinson)
    Lugain, son of Irgalach, son of Eignich, son of Cormac, son of Fergus, son of Aed, son of Cormac, son of Cairpre Dam Argait.

    An early genealogy for Clann Ceallaigh:   (Rawlinson)
    Ceallach, son of Tuathal, son of Maelduin, son of Tuadan, son of Tuathal, son of Daimíne, son of Cairpre Dam Argait.

    The Annals cite for the term Cremthainn:


    Mugdorna - Co. Monaghan. The Mugdorna territory stretched from Monaghan, where it is preserved in the name Cremourne (Crích Mugdorna "the territory of the Mughdorn"), south to as far as the river Boyne at Navan. As noted in entries in the Annals below, the territory of Mugdorna in the 9th and early 10th centuries was divided into Mughdorn Maighean and Mughdhorn Breagh, indicating a division of north and south, with Breagh referring to an area in or near eastern co. Meath.

    The early chiefs of Mugdorna are stated to be descendants of one of the Three Collas, i.e. Colla Mend. In its history the area originally referred to as Mughdorna was eventually sub-divided into the smaller kingdoms of Ui Meith, Dartraige (now Dartry), Fir Fearnmhaigh (now Farney), Conailli (now part of co. Louth) , Fir Ros (now the area about Carrickmacross), and Mugdorna [now Cremorne]. Refer to other sections on this page for more information on the ruling septs of these regions. The Ua Machainen sept are noted in the annals as lords of Mughdhorn in the 11th and early 12th centuries, probabaly at a time when the region of Mughdhorna was more limited in size, possibly centering on the barony of Cremorne in co. Monaghan. The Ua Machainen's (O'Mochoidhein) are also mentioned in O'Dugans famous topographical poem.

    Fernmag, or Fernmaighe - The area around Lough Ooney, aka Loch Uaithne near Smithborough in the barony of Dartry, co. Monaghan, was apparently referred to at an early date as Fernmag or Fer Fernmaighe (or part of). Later migration to southeast county Monaghan apparently brought the territorial name with it (Farney). An early genealogy of Fernmaigi goes back to one of the three Collas, i.e. Colla Fochríth (aka Colla Da Crich). Uí Lorcáin and Uí Chríochain (O'Creehan) appear in the annals as chiefs of Fernmhaighe (Farney) in the 11th century. O'Dugan (Poems) mentions O'Criodain and O hAedha over groups in Feara Fearnmaighe. The O'Carrolls are cited as overlords of Oriel in this area by the 12th century. MacMahon (MacMathghamhna) were noted as chiefs here in the 13th century.
    O'Kieran (Ó Ciaráin) is given as a chief of Fearnmuigh by the writer O'Dugan as a clan of Tir Eoghan.

    Airthir (Airtheara) - was centered in Co. Armagh, about the eastern baronies of Orior. In earlier times the term Airthir (literally meaing 'east') may have included most of co. Armagh. The early genealogies cite Fiachra Cassán, son Colla Fochríth, as progenitor of some of the early people of the territory of Airthir in Ard Macha (Armagh). The Airthir had split into the main septs by the 8th century, the Uí Nialláin, the Uí Bressail, and the Uí Echdach. About the 10th century, some of the major groups in the modern co. Armagh region included the Uí Méith, the Uí Nialláin, and the Uí Bresail. In the 12th century, the Irish Annals note Ua Ruadhacain (O'Rogan) as chiefs of Airthir, an area which may have been more restricted in size. The Ua Ruadacháin were noted as chiefs of Uí Eachach (Echdach), tributary to the O'Hanlons at the time, in Smith's The English in Louth 1170-1330.
    O'Dugan (Poems) mentions the two kings over Oirtheara as O hIr, and O hAnlauin.

    For the term 'Airthir', the Annals cite:


    Uí Nialláin (Clan Cernaich) - The baronies of Oneilland East and West in modern county Armagh seems to have have derived their name from the ancient territory of Uí Nialláin. From an early date the Airthir kings of the Ui Nialláin sept ruled from Loch Cal (Loughgall) just north of Armagh. The Ua hAnluain (O'Hanlon) sept, among others, were noted as chiefs of Ui Niallain as early as the 10th century. They continued as chiefs in the area of the Oriors for the next few centuries.

    Uí Bresail - northern Armagh. The O'Garvey (O Gairbhith) sept, from the same stock as O'Hanlon, held sway in Armagh on the southern shore of Lough Neagh (Oneilland East) before being displaced by the MacCann's, lords of Clanbrassil. The Annals for 1155 cite Amhlaibh Mac Canna as 'pillar of chivalry and vigour of Cinel Eoghain." Other noted chiefs included O'Keelaghan (O Ceileachain) of Uí Breasil Airthir. O'Dugan (Poems) cites the sept of O'Gairbhith fierce chiefs of Ui-Breasial of Macha, as well as the sept of Mag Duilechain over Clann Breasial. O'Dugan goes on to note the sept of Ui Lorcain over the high eastern Ui-Breasail, and also the septs of the O'Longains, O'Duibheamhnas, and O'Conchobhairs all of the western Ui-Breasail.

    MacFirbhis (Book of Genealogies) describes Mac Cana (MacCann) as chief of Cenél Aengusa, in county Armagh at the mouth of the Bann. O'Hart (Pedigrees) indicates the MacCanns (of Co. Armagh) and McMahons (of Co. Monaghan) shared the same Arighiallan ancestry, i.e. in descent from descended from Rochadh, the son of Colla-da-Chrioch.
    Note: There is also a Clan Bresail, alias Muinter Domnalláin, cited between Ballinasloe and Loughrea in Ui Maine (Connacht).

    The Annals note:


    Uí Méith - northern Co. Louth, eastern Armagh and later in Monaghan. Imchad, the son of Colla Fochríth (one of the 3 Collas) is cited as progenitor of the Uí Méith in the early genealogies. Hanratty (O hInnrechtaigh) were styled as lords of Ui Meith with territory in northern Co. Louth before being pushed into Monaghan by pressure from the Anglo-Normans. The Ua hAnluain (O'Hanlon) sept were cited as chiefs of Ui Meith Tiri, "now the barony of Orior" in Armagh, and O'Dugan (Poems) places them over Oirtheara (Orior).
    John O'Donovan in his notes on the Annals of the Four Masters cites, "Ui Meith - There were two groups of this name in the ancient Oirghialla, one called Ui-Meith Macha. alias Ui-Meith Tire, who were seated in the present barony of Monaghan, in the County of Monaghan; and the other Ui-Meath-Mara [Omeath], seated in Cualigne, in the north of the County of Louth." O'Dugan mentions O hInnreachtaigh as a king of Ui-Meith Macha, and the Annals mention them frequently. O hAinbhith, who are also mentioned in the annals as lords of Ui Meith, are given by O'Dugan as lords over noble Ui-Seaain.
    The text H. 3, 17, T.C.D. notes the Sogain (of Ulst.?), Ui Echach Coba, Ui Meith Macha and Conaille Murthemne are of the same stock, indicating a possible difference in the genealogy of the Ui Meith Macha and the Ui-Meath-Mara.

    Ui Tuirtre - The territory of the Ui Tuitre was also said to have included an area west of Lough Neagh (in modern co. Tyrone), as well as northwest of the great Lough in the modern barony of Loughinsholin, co, Derry. Loughinsholin itself is said to derive from the "lough of the island of the O'Lynns", i.e. the O'Flynn, chiefs of Ui Tuirtre. Groups of the Ui Tuitre were apparently driven east across the river Bann by the rise of the O'Cahans about the 12th century, and are later recorded in the central baronies of Co. Antrim, i.e. Toome and Antrim.
    The Ui Tuirtre genealogy goes back to Fiachu Tuirtri, son of Colla Óiss (Uais). One lineage is cited as: Bressal, mac Fergusa Forcraid, mac Máel Fothardaich, mac Suibne, mac Furudráin, et supra. O'Donnelan, Mulrooney, and O'Flynn are noted chiefs in the 11th century. After this time the O'Flynns (O'Lynns) were dominant chiefs of Ui Tuirtre, they being claimed as a senior branch of Clanna Rury of Ulidia. The neighboring territory of Fear Li (Fir Li) was (also?) in the barony of Coleraine (northeast co. Derry), and the O'Flynns (O'Lynns) are cited holding the kingship of both Tuirtre and Fir Li, at various times. O'Dugan (Poems) in the Orghialla section of his poem cite O'Floinn and O'Domhnallain as lords of Ui-Tuirtre.
    Francis Byrne in his Irish Kings and High Kings states the Uí Maic Caírthinn south of Lough foyle, the Uí Fiachrach Arda Sratha and Uí Thuirtri west and east of the Sperrins were collectively known as the Uí Macc Uais.

    Fir Lí - Feara Li, or Fer Li, i.e. the men of Mag Lí, was located west of the River Bann in the barony of Coleraine, Co. Derry. The Book of Lecan notes that Fir Li (and Ui mac Uais) in Ulster extended from Bir (Moyola river) to Camus (south of Coleraine). The Moyola river was anciently the boundary between the Feara Li and the Húi Tuirtre. The Fir Lí are noted as an Aighiallan people who came under the dominion of the Cenél Eóghain by the 9th century. Their neighbors appear to have been the Ui Tuirtre and factions of both groups are said to have been driven to the east of the Bann (into Ulidia) by the advance of Ua Cathain of the Cenel Eoghain. Another Airghiallan group, the Fir na Chraíbe, were also noted at an early date in the region west of the Bann.

    The sept of Ó Floinn (e.g. O'Lynn) became kings of Uí Thuirtre and Fir Lí by the late 12th century, and the territory name, Loch Inse Ui Fhloinn, is remembered in the name of the barony of Loughinsholin, in southwest county Derry. This was within the traditional territory of the Uí Thuirtre and Fir Lí, west of the Bann.

    The annals cite:


    Derlas (Derlus, Durlais) - The location for a territory named Derlus is described by John O'Donavan in Ui Tuitre, co. Antrim. Note: There was also a Derlas located to the south of Downpatrick, now Bright (Mrechtan), in co. Down, in Uí nEchach country; and yet another cited in Tethba.
    As the Ua Floinn (or O'Lynn) are described as chiefs of Durlas in the 12th & 13th centuries, and McLysaght places them in southern Armagh (between Lough Neagh and the sea), perhaps the country of Derlas was on the Armagh-Down border. McLysaght cites the Ua Floinn lineage from Clanna Rury of Ulidia, tracing their descent Colla Uais.
    Since the reference in the Annals for 'Inis Darcarcrenn' seems to be Ram's Island, near the eastern shore of Loch Neagh, the location of Derlas was likely in county Antrim. The Ui Tuitre of co. Derry are known to have moved west across the river Bann, into county Antrim, supplanting the lands of the Eilne branch of the Dal nAraide by the 10th century. Ua Floinn (O'Flynn, O'Lynn) were Ui Tuirtre leaders as were the later kings of Derlas.

    The annals cite for the general term Derlas:


    Uí Meic Uais - the Uí Meic Uais descend from one of the three Collas, i.e. Colla Óiss (Uais), an early pedigree citing Furudran (died c. 642) son of Béc m. Cuanach m. Dairi m. Feidlimidh m. Feichin m. Fiachrach Tuirtich m. Eirc m. Colla Uais m. Echach Doimlen.
    Francis Byrne in his Irish Kings and High Kings states that the Uí Maic Caírthinn south of Lough Foyle, the Uí Fiachrach Arda Sratha and Uí Thuirtri west and east of the Sperrins, were collectively known as the Uí Macc Uais. However, groups of this name are also noted in the midland region.
    The Annals cite territories of Uí Meic Uais in the regions of Midhe and Brega, that is, within modern counties Westmeath and Meath. 12th centrury septs included Ua Comhraidhe (O'Curry) of Uí Mac Uais Mide (Moygoish barony, co. Westmeath), as well as Ua hAonghusa (O'Hennessy) of Uí Mac Uais Breg (Upper Kells/Lower Navan baronies, co. Meath).

    A genealogy of the Uí Meic Uais:   (Book of Ballymote)

    The Annals cite for Uí Mic Uais:

    Cenel mBecce, claim descent from Bec son of Cuanach (Book of Ballymote), a king of Airgialla (possibly the late 6th century king of Uí Mic Uais). Early reference cites mac Cuanach of Cell Maeláin, in Magh na Selga in Ulster.
    As such their early genealogy appears to be:   Bec (ri Airgiall) m. Cuanach mc. Dairi mc. Feidhlimidh mc. fEchin mc. Fiacrach Tuirtri mc. Echach mc. Colla Uais.
    The same descent is claimed for Uí mac Carthainn.

    Fer Manach, aka Fir Managh, of co. Fermanagh are treated on another page.


    Uí Fiachrach Arda Srátha - Medieval chiefs of Uí Fiachrach Arda Strátha were cited as Ó Críochain (O'Crehan or Creighton?) of Ardstraw, Co. Tyrone, as well as Ó Aedha (O'Hayes or Hughes?) who were also chiefs of Fir Luirg. Arda Srátha was part of a wide area in modern county Tyrone that was tributary to the Cineal Eoghan (the northern Ui Neill).
    The Uí Fiachrach of Arda Sratha are unrelated to the other Uí Fiachrach groups, which are located in Connacht. Instead, their descent is given from Fiachra mac Eirc mic Colla Uais.
    John O'Dubhagain in his Topographical Poems cites the sept of "O hEirc, over Ui-Fiachrach Finn," a reference to the territories of Airghialla. The sept of O hEirc, chiefs of Hy-Fiachra Finn, are noted by O'Hart in the barony of Massarene, modern co. Antrim. They also claim descent from the three Collas.
    Francis Byrne in his Irish Kings and High Kings states the Uí Maic Caírthinn south of Lough Foyle, the Uí Fiachrach Arda Sratha and Uí Thuirtri west and east of the Sperrins were collectively known as the Uí Macc Uais.

    An early genealogy of the Uí Fiachrach Arda Sratha is:   (Book of Ballymote)

    The annals cite:


    Síl Daim Argait - The early genealogy is cited in Laud 610 as Daim Argait (Corpri) son of Echach son of Cremthaind Leith son of Feicc son of Dega Duirn son of Rochatha son of Colla Fochríth. Among the prominent groups included in Síl Daim Argait included Sil nDaimine and Clann Lugainn of the modern county Fermanagh area.
    Throughout the 11th and 12th centuries the Kings of Fermanagh - O'hEignigh, O'Maolruanaidh and O'Dubhdara - were drawn from the Airghialla, its Clann Lugainn branch, which is stated in the early genealogies to go back to one of the three Collas, i.e. Colla Fochríth. O'Dugan (Poems) mentions Ui hEignigh and Muintir Maoilruana as "two kings over the good slopes of Monach". He also cites a sept of OhEignigh over Clann-Cearnaigh, and apparently in connection with Ui Lorcain of eastern Ui-Breasail. O'Heany or Hegney (Ó hEignigh) and Mulrooney (Maolruanaidh) were noted as kings of Fermanagh (Fer Manach, or Fir Managh) until becoming tributary to the Maguires (Meicc h-Uidir of clann Lugain) by the 13th century.

    For a citation from the Annals, see Fir Managh.



    Dartraige - remembered in the barony of Dartree in west co. Monaghan, it was also referred to as Dartaige Coininnsi. The O'Boylan (Ó Baoighealláin) sept are cited as early kings of Darty (Dairtre) in Orghialla. O'Dugan mentions the Muinter Baoigheallain in his Topographical Poem. From the same stock as the O'Flanagans of Fermanagh, the territory of Ó Baoigheallain (O Boylan) during early medieval times, as lords of Airgialla, stretched from Fermanagh to Louth before being reduced by the MacMahons.
    There was also a Dartraige centered in Breifne.

    The Annals cite for Dartraige:


    Uí Briúin Archaille - Their early genealogy is cited from Brian son of Daig Duirn son of Rochaid son of Colla Fochríth. e.g. Book of Ballymote. Their territory is described in Onomasticon Goedelicum in the barony of Dungannon, co. Tyrone, which is located on the western side of Lough Neagh.

    The Annals cite:


    Uí Labrada - The early genealogy is cited from Labraid son of Daig Duirn son of Rochaid son of Colla Fochríth. Where the Uí Labrada hailed from, or what surnames evolved from this group, this editor is unsure.

    The Annals cite:


    Uí Dorrthainn - Onomasticon Goedelicum cites the Ui (Dorthinn, Dorthaind, Dorethainn, Tortain) in Brechmag, centered perhaps near Ardbraccan, 2 miles west of Navan, co. Meath. The early genealogies cite Dorthon, son of Fiacc, son of Feideilmid, son of Fiachra Cassán, son of Colla Fochríth, as progenitor of the tribal group referred to as Uí Dorthain.

    The Annals cite:


    Uí Echach - The Uí Echach of Oirgialla, in Tuath Echach, comprised the barony of Armagh, in modern county Armagh, as suggested by Leabhar na gCeart and by O'Donovan's edition of Topographical Poems of O'Dugan and O'Heerin). The Ui Echach bega and the Ui Echach móra, of Síl Colla Focrích (the race of Colla-dá-chrich), from MacFirbis and the Book of Ballymote, may relate to this reference and region. The text H. 3, 17, T.C.D. however place these in Dalaraide, perhaps a reference to Ui Ethach Cobha.
    The Airthir (of Airghialla) had by the 8th century split into three main septs, the Uí Nialláin, the Uí Breasail, and and the Uí Echdach. The Síl Ciarain Ua nEchach were located in Airtheraib in Ulster, according to the Book of Lecan and Book of Ballymote. An Oriel sept of Ua Ruadhacain (O'Rogan) is cited in (or near) Armagh prior to the 13th century. O'Dugan (Poems) cites Clann-Ruadhagain and the O'Domhnaills, as the two noble tribes of Ui-Eathach in Oirghialla.

    Coba vs. Arghialla: Were there two adjacent Ui Echach territories with two separate genealogies? The Ui Ethach Coba (Ui Ethach Uladh in the baronies of Iveagh, in co. Down) were a powerful group (of Dál n-Araidhe descent) in adjoining county Down, however the Book of Fenagh and Leabhar na gCeart make note of an Ui Echach (baronies of Iveagh, co. Down) as a sub-territory of Airghialla. In Place-Names of Northern Ireland, for County Down, it cites The Ui Echach were also known as the Ui Echach Coba to distinguish them from similarly named groups, to the east in the Ards peninsula (Ui Eachach Arda), and to the west in Airgialla. The diocese of Dromore reflects the earlier boundary between Ui Echach Coba and Airgialla, in that it includes the Armagh parishes of Seagoe and Shankill and follows the river Bann all the way to Lough Neagh . . . The north-western boundary of the diocese follows the River Bann from Knock Bridge (on the modern boundary with Co. Armagh) all the way to Lough Neagh, and includes the district of Clanbrasil, now the barony of Oneilland East. Clanbrasil was traditionally part of Ui Echach but was annexed to the new County of Armagh in 1605.

    Other northern septs: The Uí Echach na hÁrda, of the ards of county Down, are given in descent from Eochaid Gunnat in the Book of Leinster. The Cinel-Eachach are noted by Seamus O Ceallaigh in the Airghiallian kingdom of Ui Fhiachrach of Ard Sratha (Ardstraw, Co. Tyrone). The Cenél Echach ín chodaig are noted (in H. 2, 7, T.C.D.) as a branch of the Bredcha (Brédach) in descent from Eochaid mac Eogain.

    An early Uí Echach (Sil Colla Fochri) genealogy:   (Book of Ballymote)
    Murcad m. Ruaidri m. Muiredaich m. Ailella m. Cumascaigh m. Echadon m. Ruadacan m. Cellaich m. Ruadrach m. Conmaeil m. Airmedaich m. Feradaich m. Amalga m. Aililla m. Echach m. Feidlimthe m. Fiachrach m. Colla Da Crich.

    The Annals cite for the general term Echach:


    Uí Cormaic - The early genealogies cite Brion, son of Echach, son of Colla Uais, as progenitor of some of the early people of the territory of the Uí Cormaic. We find the name O'Corbmaic cited by O'Dugan (Poems), over the valiant Ui MacCarthainn.
    Note: not to be confused with Ui Cormaic in co. Clare; or the Síl Cormaic of Leinster; or Ui Cormaic Maenmhaighe in Ui Maine; or Ui Cormaic in Tír dá glas, co. Tipperary.
    The Book of Leinster mentions a Cenel Chormaic, in Meath, of the Clann Lugain branch, so called from Cormac mac Cairpri Damargait. O'Flaherty's Ogygia cites an Uí Cormaic in Ui mac Carthainn.

    The Annals cite for the general term Cormaic:


    Uí mac Carthainn - near Lough Foyle, Tirkeeran, co. Derry, according to Onomasticon Goedelicum. O'Flaherty's Ogygia cites an Uí Cormaic in Uí mac Carthainn. O'Dugans topographical poem cites O'Corbmaic, over the valiant Ui MacCarthainn, and goes on to note the chieftains of Ui Meic Carthainn as O'Colgan and O'Connell (perhaps two separate regions in Oirghialla).
    Francis Byrne in his Irish Kings and High Kings states the Uí Maic Caírthinn south of Lough Foyle, the Uí Fiachrach Arda Sratha and Uí Thuirtri west and east of the Sperrins were collectively known as the Uí Macc Uais.
    A Tír Mac Cartainn is cited by Goedelicum east of the barony of Boylagh in county Donegal.

    An early genealogy cites a lineage for an Uí mac Carthaind from Colla Uais, i.e. Cairthand (a quo H. Mc. Carthaind), son of Eichin, son of Bec (ri Airgiall) m. Cuanach m. mc. Dairi mc. Feidhlimidh mc. Echin mc. Fiacrach Tort mc. Echach mc. Colla Uais.

    The Annals cite:


    Uí Tréna - located in co. Armagh?, Craebh Carthaind is described in it. They are claimed to be descended from Trian son of Feidhlimidh, son of Fiachra Cassan, son of Colla Da Crich.
    Not to be confused with Ui Trena, in the territory of Ui Ceinnsealaigh, in Leinster. Not to be confused with the Ui Trena of Munster.

    The Annals cite for the general term Trena:


    Uí Cennfhada - Tír Cendfhada, aka Ui Cennfota or Ui Ceinneidigh, gave its name to the barony of Tirkennedy, co. Fermanagh. The Uí Ceinneidigh are noted in the general area in the 12th century, and the sept of Ó Daimhín are later given as chiefs here, according to the Irish Annals. The Ui Cennfhota are claimed to descend from Fergus Cennfhota son of Cremthann, the eponymous ancestor of the Ui Chremthainn. In the same lineage, Ó Daimhín claims descendancy from "Daimhin" who died in 966, a son of Cairbre Dam Argait, King of Oriel. Their surname may have been anglicized as O Davin, rather than O Devine.

    The Annals cite:


    Fir Lemna - or Uí Tuathail, the Fir Lemna were cited as one of the Trí Tuatha of Oirghialla (along with Síl Dubthir and Ui Cremthainne). Fir Lemna is thought to have been near Clogher (Clochar mac nDaimin) in modern county Tyrone. Another name for it was given as Síl Tuathail in Tuaiscirt. Mag Lemna is given in the parishes of Clogher and Errigal Keerogue in southern co. Tyrone and bordering co. Monaghan. Their ancestry is claimed from Tuathal, son of Daimíne (a quo Síl Daimini), son of Cairpre Damargait, son of Echach, son of Crimthann, son of Fiacc, son of Daig Duirn, son of Rochaid, son of Colla Fochríth. O'Dugan (Poems) notes the sept of O'Caomhain as a king of Magh Leamhna. King of Magh Leamhna

    The Uí Neill sept of Mac Cathmaoil (the McCawells, alias Campbells) were chiefs of Clann Fogarty which included the barony of Clogher, co. Tyrone. Mac Cathmhaoil were cited as a chiefs of Cenél Feradaig (Kinelfarry), of Clann Oengusa, and of Clann Duibinrecht, and of Clann Fogartaig according to the Annals of Ulter.

    The Annals cite:


    Síl Duibthir - mentioned with Fir Leamhna and Ui Cremthainn as one of the Trí Tuatha of Airghialla. The sept of Ua Laithéin are noted as chiefs of Síl Duibtire in the 10th/11th century.
    O'Dugan (Poems) cites the tribe of Duibhthire, over the Clanna-Daimhin in Oirghialla, quite likely a reference to Síl Duibthir.

    The Annals cite:
  • U1018, Gilla Críst, son of Conaing son of Congalach, i.e. the chief of Clann Sínaig, died.
  • U1038, Orc Allaid ua Ruadacáin, king of Uí Echach, was killed by the Clann Sínaig in Ard Macha on Monday the feast of Ultán 4 Sept., in revenge for the killing of Eochaid son of the Abbot and for the profanation of Ard Macha.
  • U1059, Gilla Muire son of Airechtach, chief of Clann Sínaigh, was killed in Airthir.
  • U1086, Gilla Moninne ua Eochada, chief of Clann Sínaigh, fell.


    Muinter Pheodachain - their territory described as west of Lower Loch Erne, including much of the modern baronies of Magheraboy and Clanawley, co. Fermanagh. They were represented by the family of Mac Gilla Fhinnein (Mac Alinion), chieftains of Muinter Pheodachain. Their ancestry is disputed however one citation gives their ancestor as Peodachan, grandson of Elganach of clann Cormaic, in descent from Cairpre Damargait. Other sources claim they descend from the Cenel Conaill (northern Ui Neill), while another source (Fermanagh genealogies) cites them as descendants of the Munster Eoganachta!

    The Annals cite:


    Uí Dáire - The early genealogies cite Dáire, son of Ercc, son of Echach, son of Colla Uais, as progenitor of some of the early people of the territory of the Uí Dáire.



    Uí Meic Brócc - The early genealogies cite Echdach Amainsen, son of Crimthann, son of Fiacc, son of Daig Duirn, son of Rochaid, son of Colla Fochríth, as progenitor of some of the early people of the territory of the Uí Meic Brócc.
    Note: not to be confused with Uí Meicc Brócc, a segment of the Eóganacht in county Kerry.



    Dál n-Oaich - The early genealogies cite Crimthann Oach, son of Fiacc, son of Daig Duirn, son of Rochaid, son of Colla Fochríth, as progenitor of some of the early people of the territory of the Dál n-Oaich.



    Fir Lurg - barony of Lurg in Co. Fermanagh. The sept of O Maolduin (O'Muldoon) is noted here as chiefs (and early kings) of Lurg, aka Fir Lurg, Fear Luirg or Fer Luircc. O'Dugan mentions Muinter-Maoilduin of Lurg in his Topographical Poem. They were subjugated by the MacGuires at the end of the 14th century.
    The Fir Luirg were listed among the Síl colla uais, descendants of Colla Uais.

    The annals cite: Ui Laoghaire of Loch Lir - O'Hart (Pedigrees) describes Muintir Taithligh (e.g. Tilly, Tully or MacTully) as chiefs of Hy-Laoghaire, of Lough Lir, a district which lay in the barony of Lurg, near Lough Erne, towards Tyrone. O'Dugan (Poems) mentions the Muinter Tiathligh as chieftains over the Ui-Laeghaire of Loch-Lir. O'Donovan desribes Ui Loeghaire Locha Lir in Tyone, east of the barony of Lurg in County Fermanagh. The Caislén Locha Laoghaire (castle of Loch Lir) is desribed in O'Donnells land in the index to the Four Masters. The Crannach Locha Laeghuiri is described in the same source in Baronscourt demesne, 2 miles west of Newtown Stewart, county Tyrone, with its castle was pulled down by Docwra in 1602.

    Note: Not to be confused with Ua Caindelbhain, kings of Laeghair in Meath; or with Ua Donnchadha, kings of Cenel-Laeghaire in Munster; or with Ui Laoghaire (O'Leary) in Co. Cork.

    The annals cite for Laeghaire in this general region:


    Fir na Craoibhe - or Creeve, near Coleraine, on the west of the river Bann, where Eas Craoibhe, or the Cutt's Fishery, is located, according to O'Donovan (Four Masters). It is equated with Faranacryve in the barony of Keenaght, county Derry, in Primate Colton's Visitation. The Cenél mBinnigh, of the Cenél Éoghain are cited to have migrated to this area at an early date. Later, the Clan Conchobhair, of the Cenél Éoghain, migrated into this region, the Ua Cathain (O'Kane) noted as chiefs of Fir na Craoibhe by the 12th century.

    The annals cite:


    Fir Rois - Feara Rois, or Fer Rois, was located in south Airghialla. Locations for Fir Roiss are cited in Onomasticon Goedelicum in the barony of Farney, co. Monaghan, and in the barony of of Ardee, co. Louth, and in Meath. Crích Ross stands 4 miles northewet of the point where counites Monaghan, Louth and Meath meet. An O'Finn sept is noted here as chiefs prior to the coming of the Anglo-Normans. O'Dugan (Poems) mentions O'Cosgraigh as king of smooth Feara-Rois.

    An early genealogy of the Fir Rois:
    Gairbith m. Maileidig m. Feradaich mc. Finain m. Failbi m. Duibthaich m. Crundmail m. Fathaich m. Faelbi m. Lugdach mc. Fiacrach Cenn Findain (a quo hI Ceind Find) m. Feidlimid.

    The annals cite:


    Tuath Rátha (Toorah) - Ui Fhlannagáin (O'Flanagan) is cited in Topographical Poems as chief of Tuath Ratha, and O'Hart gives this as a territory which extended from Belmore to Belleek, and from Lough Melvin to lower Lough Erne, comprising the present barony of Magheraboy, co. Fermanagh. Tuath-Rátha is cited as one of the sub-denominations of Tír Conaill in the Book of Fenagh.
