Old Irish Surnames
The Northern Ui Neill were divided into two main branches, Cenel Conaill and
Cenel nEoghain. Cenel Conaill were the more powerful from the late sixth to
the middle seventh century, with Flaithbertach mac Loingsig abdocating the
overkingship of the Ui Neill in 734 A.D. The Cenel nEoghain next dominated
and by the late eighth century had expanded southwards and eastwards from
Inishowen and Derry across the mid-Ulster plain and slowly brought the minor
kingdoms ruled by the Airgialla under their control. The Ulaid in the east
and Cenel Conaill in the west remained bitterly hostile to the dominant
The Southern Ui Neill were divided into two major rival branches, the Sil
nAeda Slaine and Clann Cholmain, and they dominated the lands of Meath, Westmeath
and other parts of surrounding counties. The Sil nAeda Slaine were very
powerful in the seventh century. The annals record the slaying of Finsnechta
Fledach macDunchada, king of the Sil nAedo Slane, by his rivals the Fir Chul
of the Luigne of Brega (Tara). Clann Cholmain managed to take the
overlordship of the Ui Neill in 743. In the mid-ninth century their king
claimed to be king of Ireland.
In the eighth century Leinster (Laigin) was ruled by the Ui Dunlainge. They
had other rivals to the south of them, the Ui Chennselaig. The Ui Neill
pursued a long struggle with the Laigin and by 800 came to dominate
northern Leinster. East Leinster was ruled by the Ui Cellaig Cualann in the
seventh and eighth centuries.
The Eoganacht ruled Munster from the seventh to the mid-tenth century. Prior
to that the Erainn or their descendants, the Corca Loigde, ruled in Munster.
The eastern branches of the Eoganacht, located at Cashel and Glanworth, began
to dominate from about 700 A.D. Eoganacht power began to crumble in the
late ninth and early tenth centuries and their place was taken by the Dal
Cais, whose power rose from north Munster (Thomond) in the mid-tenth century.
The two dominant Connacht dynasties were the Ui Fiachrach and Ui Briuin, and both
claimed to be cousins of the Ui Neill. Ui Fiachrach had two main branches,
one in the north (Muaide) and the other in the south (Aidne). The southern
branch dominated Connacht and much of north Munster in the seventh century.
Ui Briuin emerged in the seventh century, and their expansion in the eighth
century was fast, Ui Fiachrach lost ground rapidly, and by about 725 Ui
Briuin were the dominant dynasty in Connacht. A branch pushed north and
east to establish the kingdom of Ui Briuin Breifne around 766 on the
frontiers of the Ui Neill in the territory of the Conmaicne Rein,
eventually driving a wedge between their two great branches. In the
twelfth century the Ui Briuin were dominant in Ireland.
In the late eighth and early ninth centuries, raids by the Vikings began.
These Vikings were mainly Norwegians and by the mid ninth century had established
a foothold in Dublin. Other Viking raiding camps included Waterford,
Youghal, Wexford, Cork and Limerick. A second period of intensified Viking
raids began in the early-mid tenth century as settlements began to be
