Ruaidrí mac Tairrdelbach Ua Conchobair was King of Connacht from 1156 to 1186, and High King of Ireland from 1166 to 1198. He was the last High King of Ireland before the Anglo-Norman invasion.
The Mac Lochlainn were a leading branch of the Cenél nEógain and during the early medieval period, the most powerful clan in the Northern Uí Néill. They descended from Domnall Dabaill, son of Áed Findliath. Another son of the latter was Niall Glúndub eponymous ancestor of the Ua Néill. As a result of their descent from Domnall Dabaill, the Mac Lochlainn were known as Clann Domnaill or Clann Domhnaill. The eponym behind the surnames Mac Lochlainn andÓ Lochlainn,—is Lochlann mac Máelsechnaill, King of Inishowen. The surnames themselves formed not as a result of Lochlann's prominence, but as a consequence of the remarkable success of his grandson, Domnall Ua Lochlainn.
