> 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." There is a handfull of Murphy DNA results from county Armagh (plus county Down) and none are M222+ (MacMurphy of Clann Birn kingship was Trough at the intersection of the counties Monaghan, Armagh and Tyrone). I would add another variant to MacMurphy, MacMorrow or MacMurray, that of O'Morgan (O'Muireagain one of the five chief families of Ui Tuirtre of Clann Colla (though also identified with Ui Chremthainn) and also driven to south Armagh and south county Down by the O'Neill expansion), also not M222+. I suspect a common practise of pedigree fixing to incorporate allied families (in this case former local rulers) into the political structure of kinship rights.
