CAOMHAN, a younger brother of Dubhda, who is No. 97 on the "O'Dowd" pedigree, was the ancestor of O'Caomhain; anglicised O'Keevan, Keevan, Kevin, Kevens, Keveny, Kavanagh (of Connaught), Coen, Cohen, Cohan, Cowan, and Cuan. This Caomhan was Chief of his Sept, A.D. 876.

The O'Keevan portion of the family, who were also known as Muintir Keevan, possessed the district of Moylena, in the county Tyrone, which was lately known as "The Closach;" and the Armorial Bearings of that branch of the O'Caomhain family are—

Arms: Vert a saltire or, betw. in chief and in base a lizard pass. of the last, and in fess two daggers erect ar. pommels and hilts gold. Crest: A dagger erect ar. pommel and hilt or, the blade impaling a lizard vert.

Tracing the pedigree to its source: Caomhan was son of Conmac, son of Duncatha,son of Cathal, son of Olioll, son of Donoch, son of Tiobrad, son of Maoldubh, son of Fiachra Ealg (or Ealgach), son of Dathi, the 127th Monarch of Ireland, son of Fiachra, brother of Niall of the Nine Hostages, whose son Eoghan (Owen) married Indorba, a princess of Britain.

The descendants of this last mentioned Fiachra were called Hy-Fiachrach; and gave their name to Tir Fiachrach, now known as the barony of "Tireragh," in the southern portion of the county Sligo. They also possessed the territories now constituting the present baronies of Carra, Erris, and Tyrawley, in the county Mayo. Beal-atha an-fheadha (os vadi sylvae), now the town of "Ballina," being their chief seat.
