Background on the Northern Uí Neill

The sons of Niall of the Nine Hostages, Eoghan, Conall [Gulban], and Enda, travelled north from the kingdom of Connacht into the western and northern regions of the kingdom of Ulster (county Donegal). It was here in the 5th century that the Cenél Eóghain and Cenél Conaill began to establish themselves as overlords in northwestern Ulster. The Cenél Eóghain established their power base at Inishowen and their capital at Aileach. The Cenél Conaill centered themselves around the rich area of Magh Ithe, in the valley of the river Finn. The two clans alternated as kings of the North up to the 8th century. The Northern Ui Neill also alternated with their southern cousins as so-called 'sovereigns of Ireland' into the 10th century.

In the 8th century a series of victories were gained by the Cenél Eóghain over the Cenél Conaill in Magh Ithe (east Co. Donegal), splitting their power between the territories of Fanad, in the north, and Tir nAeda, in the south. By the beginning of the 9th century the Cenél Eóghain were the dominant Northern dynasty, as they spread their influence east into modern county Derry, pushing aside the Cruithin east of the river Bann, gaining control over the Ciannachta of mid-Derry, and steadily encroaching on the Airgiallan tribes of Ui Macc Uais. The dominance of the Cenél Eóghain continued as they drove further south, subjugating other Airghiallan tribes, and by the 11th century the Cenél Eóghain had moved their power base from Aileach to that near Tullahogue in modern day county Tyrone (named from Tir Eóghain, or Tir Owen). By the 12th century much of the area of Magh Ithe, and later that of Inishowen, was taken by the O'Donnells and O'Dohertys of Cenél Conaill. By the mid 13th century a leading family of the Cenél Eóghain, the Mac Lochlainn (McLoughlin), began to lose prominence to their kinsmen, the Ó Neill.

There are many notable northern Uí Neill clans which included O'Neill, O'Donnell, MacLoughlin, O'Donnelly, O'Doherty, O'Cannon, O'Muldory, O'Kane, O'Gallagher, O'Gormley, O’Flaherty or O’Laverty, O'Hamill, O'Lunney, O'Carolan of Clan Diarmada, O'Quin, O'Hagan of Tullahogue, O'Devlin of Munterdevlin, among many others.

Cenél Eóghain
Eoghan was the son of Niall who established his kingdom in Innishowen, centered at Aileach. Eoghan's sons included Muiredach, Binech, Fergus, Óengus, Dallán, Cormac, Feideilmid, Ailill, Echen, Illann, and Eochaid. Some of the clans of the Cenél Eóghain included those of Clan Neill, Clan Domnaill, Clan Birn, Cenél Fergusa, Cairrge Brachaidhe, Cenél Binnigh, Cenél Moen, Cenél Fearadhaigh, Cenel Tigernaich, Clan Conchobhair, Clan Diarmatta.

The king, Aedh Allan himself; went into the battle, and the chieftains of the North along with him. The chieftains of Leinster came with their kings into the battle; and bloodily and heroically was the battle fought between them both. Heroes were slaughtered, and bodies were mutilated. Aedh Allan, and Aedh, son of Colgan, King of Leinster, met each other in single combat; and Aedh, son of Colgan, was slain by Aedh Allan.

Clan Neill, included the dominant Cenél Eóghain septs of Ó Neill and Mac Lochlainn, as well as many other notable septs. The name O'Neill is said to originate with Niall Glúndub, a 10th century ancestor of the Uí Neill line. The reference here to Clan Neill refers to Neill Caille, his grandfather. Ó Neill and Mac Lochlainn are anciently cited as kings of Aileach, a base of power at the lower end of the Inishowen peninsula. By the 11th century the Ó Neill had established a seat of power at Tullahogue, co. Tyrone, and later became the dominant sept of the Cenél Eóghain.

Clan Domnaill, of Cenél Eóghain. The name of O'Donnelly is said to derive from a great-great grandson of Domnaill, that is Donghaile. They were cited as chiefs of Feardroma, perhaps near Ballydonnelly, in county Tyrone. There is also a Fer Droma Lighen, a name remembered in the townland of Drumleene, Clonleig parish, barony of Raphoe, county Donegal. Of the same region, the sept of Cenél n-Echach Droma Lighen are cited in the Book of Ballymote and the Book of Lecan, descended from Eocho, son of Domhnall, son of Muirceartach Mac Earca.
The O'Donnellys are later cited at Castlecaulfield, alias Ballydonnelly (Baile Ui Donngaile), near Dungannon, in co. Tyrone.

The name Ua [F]laithbertaigh is associated as a king of Clann-Domhnaill in the Annals. Note: Not to be confused with Flaithbertaigh, king of West Connacht.

Clan Birn, descended from Bern, son of Ruadrí, son of Murchad, a quo Muinter Birn, in the line of Cenél Eóghain, according to the genealogies in Rawlinson B502. In addition Rawlinson points to a son of Bern named Anféid, a quo Tellach n-Anfida, who was possibly the namesake for Tellach Ainbhith. According to O'Dugan (Topograhipcal Poems), the MacRuaidhris were among those over Teallach Ainbhith and over Muintir-Birn. O'Hart (Pedigrees) cites the name MacRuaidhri as MacRory or MacRogers, over the same territories, districts which he places in the baronies of Dungannon and Strabane, county Tyrone. Woulfe (Irish Names) agrees and also cites the family of MacRuaidhri as erenaghs of Ballynascreen, in County Derry. O'Hart goes on to cite, under the county Armagh, Muintir Birn, some of whose descendants anglicized their name Bruen, was a district in the south of the barony of Dungannon, adjoining the territory of Trough in county Monaghan.
In Murphy surname history, there is mention of the surname Mac Murchadha (MacMurphy, Murphy), originally based in present-day Co. Tyrone, in the area known as Muintir Birn, but were driven out by the O'Neills and settled in south Armagh. The reference seems corroborated in various entries in the Annals, although the name Mac Murrough seems to be applied there, which may have later been translated into MacMorrow or MacMurray.
In Colgan's Trias Thaumaturga, it mentions Ui Briuin, now Muinter Birn, alias Ui Briuinia Aquilonaris, in county Tír Eoguin, and diocese of Ardmache. This is an apparent reference to Ua mBriúin Archaille in Ui Chremthaind, a branch of Siol Colla dá Chrich, who were also noted in the Dungannon area.
Note: Not to be confused with Muintir Birn, O'Beirne of Ui Briúin na Sinna, in county Roscommon.

Cenél Fergusa, of the Cenél Eóghain, with territory later held south of the Sperrin Mountains in Derry. Fergus was a son of Eoghan, and ancestor of the O'Hagans, O'Quins, Ua Mael Fhabaill (Mulfoyle, et al) and O'Mallons (O'Mellans) among others. Ua hOgain (O'Hagan) and O'Maelfhabhuill are cited as chiefs of Cinel-Fearghusa in the Annals. Ua Mael Fhabaill is also noted as chiefs of Cairrge Brachaidhe, cited in the northwest part of Inishowen. O'Mellan's country was said to be originally in southernmost Co. Derry, and the sept is later noted in Co. Tyrone.

Cairrge Brachaidhe. Perhaps named from Brachaidi mac Diarmata (or he named from it), the Cenél Fergusa held this territory at an early date. The Book of Lecan cites Diarmait, of Cenél Fergusa, rí Cairrce Brachaide. The sept of Ua Mael Fhabaill (Mulfaal, Mulfavil, MacFael or Mac Paul) are cited in the Annals as chiefs of Carrichbrack (Carrickbraghy) in the barony of Inishowen West, County Donegal. The Mulfaal sept claim descent from Fergus, grandson of Niall of the Nine Hostages, and are thus part of the Cenél Fergusa. O'Hogain (O'Hagan or Hogan) is cited as a chief in this region by O'Dugan (Poems).

Cenél Aedha, of Cenél Conaill, a sept descended from Conall Gulban who are said to have given their name to the barony of Tirhugh, alias Tír Aedha, in county Donegal. In Irish tradition, the naming of Tír Aedha is also cited from Aodh Ruadh, aka Tír n-Aeda Ruaid mic Badhuirnn (mic Airgedmair), a legendary monarch of Ireland and father of Macha, founder of Emain. From the same name comes Eas Ruaidh (Assaroe, now Ballyshannon), an early name for this region of Donegal.

Early prominent septs in the area of Tirhugh included Ó Maeldoraidh, Ó Canannáin (O'Cannon) and Ó Gallchobhair (O'Gallagher). The former two were in early contention for the kingship of Cenél Conaill, as noted in the Annals. By the 13th century the O'Donnells rose to dominance among the septs of Cenél Conaill, the O'Gallaghers becoming the leaders of the O'Donnell calvary.

The O'Donnells, at first lived along the river Lennon but later established themselves in south Donegal. They rose to power as kings of Cenél Conaill in the early 13th century.
The Uí Baoighill (O'Boyles) and the Uí Dochartaig (O'Dohertys) were also of Sil Lugdach.

Arda Midhair, The Ó Dochartaigh (O'Dohertys), of Cenél Conaill, were cited as chiefs of Arda Midhair (Ardmire, perhaps the Finn Valley) in the barony of Raphoe, county Donegal. At the turn of the 13th century two Ó Dochartaigh were noted as kings of Tír Chonaill, breaking a long hold the O'Cannons and O'Muldorys (Mulderrys) had on this title. Soon after the O'Donnells rose to prominence in Tír Chonaill. By 1247 the O'Donnells are noted as Lords of Inishowen for the first time (Annals), an apparent indication of Cenel Conaill expansion into a region traditionally held region by the Cenel Eoghain (Mac Lochlainn). The arrival of the Norman de Burgo family by the latter half of the 13th century saw the building of fortifications in the region. Any fear of further Anglo-Norman expansion in Inishowen and Derry, however, was halted by the murder of Earl William de Burgh in 1333, and the absenteeism of his heirs kept the path open for Gaelic dominance in the region. It was perhaps during this time the Ó Dochartaigh began to make inroads into Inishowen, as chieftains under O'Donnell. By the early 15th century the Ó Dochartaighs are noted as lords of Inishowen (Annals), and the peninsula later became known as "O'Dogherty's Country".

Cenel Duach, of the Cenél Conaill, named from Tigernach Duí (Duach), son of Conall Gulban. Nainnid son of Daui is mentioned in Chronicon Scotorum 563 at the battle of Móin Daire Lothair which was won over the Cruithin by the Uí Néill of the North. Chronicon Scotorum, in the year 586, notes the killing of Baetán son of Ninnid son of Daui son of Conall Gulban, king of Temair. The Annals of Tigernach cite Baedan, son of Níndedha, grandson of Conall Gulban, as a king of Tara in AD 586, i.e. Baedan mac Níndedha, maic Conaill Gulban, rí Temrach. In the Annals of Ulster, for 586, his obituary appears as "the killing of Baetán son of Ninnid son of Daui alias son of Fergus Cennfhata son of Conall of Gulbu, king of Temair, who reigned one year."

Tir Ainmireach, a name applied to an area of Ua Bhaeighill (O'Boyle) chieftainship in southern county Donegal. O'Hart (Pedigrees) calls the O'Boyles chiefs of Clan Chindfaoladh of Tir Ainmireach, and of Tir Boghaine. Originally their territory extended from Donegal town to near Kilmacreannan along the west coast. The O'Boyles are said to have given their name to the barony of Boylagh in county Donegal. With the rise of the O'Donnells in the 13th century, their territory became divided, with Tir Ainmireach (around Ardara) in the south, and the Three Tuatha (around Falcarragh and Kilmacrennan) toward the north. The MacSweeneys were brought into this area as Gallowglass to O'Donnell in the 14th century.

Rosguill, a promontory (or Ross) in the barony of Kilmacrenan, co. Donegal, between Sheep Haven and Mulroy bay, i.e. in the parish of Mevagh. O'Dugan (Poems) cites that Ros-Guill and Ros-Iorguil belong to MacGillatsamhais. Ros-Iorguil, or Irguill, is equated to Horn Head, to the west of Ros Guill, in the index to the Four Masters. Both areas are west of Fanad. Who the MacGillatsamhais' (Mac Giolla Shamhais) were is not known.

In the same section of his Topographical Poem, O'Dugan also mentions belong to O'Cearnachain (e.g. Kernaghan) and Muintir Dalachain over Tuath Bladhach (Bladhaigh). Tuath Bladhaigh, anglicized Tuath Doe, is a well known district situated between Sheep Head and Cloghaneely, placing it to the south of Ros-Iorguil. Cloghineely is noted by O'Donovan in connection with the Ua Baighill (O'Boyles) of Cloch Cinnfhaelaidh, where they held sway until perhaps the second half of the 14th century. Here they are cited as chiefs of na Trí Tuath before the MacSweeneys. The areas of Rosguill (now Downing's & Carrigart), Doe (now Creeslough & Dunfanaghy), Cloughaneely (now Falcarragh ) and Tory Island, were later ruled by the Mac Sweeneys from Doe Castle. These were the MacSweeney Na Doe (Mac Suibhne na d'Tuath), lords of Na Tuatha. The district called Na Trí Tuatha, or Tuatha Toraighe, was an area extending from Ros Guill and Mulroy Bay in the east to Gweedore Bay in the west, with Tory Island included.
Note: Trí Tuatha, not to be confused with the Three Tuatha of county Roscommon.

M1603, Hugh Boy, the son of Con, was wounded in the ankle; and he was sent to Crannog-na-nDuini in Ros-Guill, in the Tuathas, to be healed.

Finn Ros, aka The Rosses, in Tirconnell, the land of the O Forananes and O Carnahanes, according to O'Brien's Irish Dictionary. O'Dugan (Poems) places O'Furadhrain over Fionn Ros, and O'Donovan translates the surname as Farran or Forran. O'Donovan in his notes to O'Dugan's Poems cites Fionn-Ros, now the Rosses, was situated in the barony of Boylagh. The Rosses are marked on a modern map of Ireland in the civil parish of Templecrone, in the far north of the barony of Boylagh. The Rosses extends from Crolly Bridge in the north to Gweebarra Bridge in the south, embracing all the intervening coastline and islands, penetrating inland as far as the Derryveagh mountains and the alpinesque village of Doochary.

The territory of Trián Íochtair Baoighellach is described by O'Donovan (Four Masters) in "The Rosses", between Aranmore Island and the Gweedore river, in county Donegal. At least a portion of the Rosses region, if not all, was connected with the O'Boyles, near of a portion of the Tri Tuath area they once held.

The annals cite:

LC1342, Conchobhar O'Domhnaill; king of Tir-Conaill, and one worthy to rule all Erinn, if God had willed it, by reason of his nobility, eminence, and the excellence of his bounty and prowess, was slain by Niall O'Domhnaill, i.e. his own father's son: (the house of Finn-ros was burned over him, and O'Domhnaill went out of the house, and fell afterwards in the doorway of his own house), after obtaining victory over the devil and the world; and a great number of O'Domhnaill's household band were moreover burned and killed there. Niall O'Domhnaill was made king by a number of the chieftains of Tir-Conaill.
M1603, Hugh Boy, the son of Con, was wounded in the ankle; and he was sent to Crannog-na-nDuini in Ros-Guill, in the Tuathas, to be healed.

Fánad, or Fanat, is the peninsula between Lough Swilly and Mulroy Bay, in the northeast of the barony of Kilmacrenan, county Donegal. The sept of Ua Bresleáin (O'Breslen or Breslin), a branch of the Cenél Enda (MacLysaght) although cited by others as a branch of Cenel Conaill, are noted as early chiefs of Fanad, later noted as Brehons for Maguire of Fermanagh. The Mac Suibhnes (Mac Sweeney Fanat) are not as chiefs of Fanad in the late 14th century.

The annals cite:

U1158, A hosting by Ua Lachlainn into Tir-Conaill also, so that he wasted Fanat entirely.
MCB1183, Defeat and, slaughter [inflicted] by John de Courcy at Cúil an Tuaiscirt on Cinéal Eóghain, [Cinéal] Conaill, and Cianachta, and Giolla Críost Ó Cathain, son of the king of Fir na Craoibhe, and Raghnall Ó Brisléin, chieftain of Fána, were killed.

M1281, Cormac, son of the Ferleighin Lector O'Donnell, Chief of Fanad, fell.
LC1399, Toirdhelbhach, son of Maelmuire Mac Suibhne, lord of Fanad, quievit.

Cenél Enda
Two distinct territories are mentioned. From Eanna (Enda), the sixth son of Conall Gulban, descended the Cinel Eanna, Kings of Magh Ith, Tir Eanna and Fanad in present day Co. Donegal. This territory was in and near the southern tip of Inishowen. (note: The cantred of Enda, son of Niall, is mentioned by the Four Masters in the year 1600).
Hogan (Goedelicum) describes the original apportionment to Enna, son of Niall, in the partition of Tirconnell, circa 400 A.D. to comprise from the boundary of Inis Eoghain to Bearnas mor (Gap of Barnesmore, near Donegal) and Sruthail (Sruell, Killyward parish, barony of Banagh, c. Don.)
According to O'Dugan (Poems), the following were chiefs of Magh Ith: O'Baoighill, O'Maiolbreasail, O'Cuinn, and O'Cionaith. Mag Ith was partly in the barony of Raphoe in Donegal, and partly in the barony of Tirkeran in Derry. O'Breslin, cited as chiefs in Fanad and noted as brehons there, are cited by MacLysaght as a branch of Cenel Enda, and by others as a branch of Cenel Conaill (descent from Fergus Fanad).

Another Cenél Endai was cited in southern Co. Donegal and possibly northwestern Co. Fermanagh. As the story goes, Enda, the youngest son of Niall of the Nine Hostages, received territory about the 5th century which extended from the river Errity to Barnesmore, barony of Tir Hugh, to Sruell in the barony of Banagh, county of Donegal. The north-western limit was Farnagh in the parish of Aughnis, barony of Kilmacrenan. The eastern limit of his lands was the river Finn.

To confuse matters, there does not appear to be evidence of a dynastic family descended from Énda existing in the North before the 11th century. All earlier references in the Irish texts seem to associate the Cenél Énda with the Cenél Fiachach and the Lóegaire in Mide and also in Connacht. For example, Ua Braonain (O'Brennan) of Creeve and Mac Ruairc (Mag Rourke, Groarke) of Teallach-Conmasa, both located in county Westmeath, claim descent from a Cenél nÉnna.

11th century chiefs of Cenél n-Enda mentioned in the annals below include ua Lapáin (O'Lappin) and ua h-Eicnechan (roughly O'Heneghan). Chiefs from Cenél Moen and Cenél Conaill are later noted in the area of Tir Enda in co. Donegal.

The annals cite:

M1010, Oenghus Ua Lapáin, tigherna Cenél n-Enda was slain by the Cinel-Eoghain of the Island.
LC1019, Flaithbhertach Ua Neill went into Tir-Conaill, and he destroyed Tir-Enna and Tir-Lughdech.

M1342, Donnell O'Doherty, Chief of Ardmire, and of the cantred of Tir-Enda, a man full of hospitality and prowess, died, and John O'Doherty assumed his place.

Cenél Cairpri [Mor]
"Críoch Cairpre Droma Cliab" of northern Co. Sligo and northeast Co. Leitrim. The territory of Cairbre, son of Niall of the Nine Hostages, around the 6th century extended from the Drowes west to the Owenmore river in Ballysadare. Duncarbry (Dun Chairbre, or Cairbre's Fort) - later a McClancy fort - marks the border of Cairbre's territory on the Drowes, while the Barony of Carbury in North Sligo today reminds us also of where he ruled. Noted chiefs of Cenél Cairpre included O'Mulclohy (Ó Maolchloiche), a name which was later mistranslated to Stone. Cairbre's descendants are said to have also settled in Grandard in the county of Longford.

Other Cairpre septs - Uí Cairpri Laigen (Ua Ciardha of Carbury, Co. Kildare); and Cairpre Gabra, near Grandard, co. Longford.
