- Clan O'Cahan (O'Cathain, O'Cahan, Keane, Kean, O'Kane, Kane, Cain, McCain).
The eponymous ancestor of the O'Cahan Clan of Ulster was Cathain (which means "one who does battle"), who lived in the 9th Century, a descendant of Fergal mac Mael Duin, King of Tara (d. 772 A.D.), ancestor of the O'Neill Royal dynasty. The O'Cahan line branched off through Fergal's son, Conchobar, and is the senior cadet branch of the O'Neills. Known as "The Warrior Clan of Ulster". The O'Cahan family were under-kings (Ur-Righ) of the O'Neill dynasty and bore the titles "King of Limavaday, Kianaght, and Fir-na-Creabh" (the latter now the Barony of Coleraine). They also were the hereditary inaugurators of the O'Neill Kings. In Ulster the name is now usually found as Kane or O'Kane in Co. Derry, while in north Antrim the form McCain is often found.
Cumagh, pronounced "Coey", is sometimes found Anglicized as "Guy". Donn = "brown". Cumagh Donn O'Cahan was either the son or nephew of Cumagh mac Mahon O'Cahan, both of whom were kings of Fir-na-Creabh (Coleraine, Ireland) and Keenaught. Cumagh mac Mahon O'Cahan was deposed in 1273. His father, Manus Of the Battle of Down was killed at the Battle of Down in 1260.
