Muinter Birn of Ulster

 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.
