Padraig Mac Giolla-Domhnaigh

Boar—Some of the name of McCullagh in North Sligo have assumed the name of Boar, reckoning that the name was derived from Cullach, a boar. Dr. McBain in his "Etymological Dictionary" doesn't make the derivation of the Galloway name, McCulloch, plain enough to confirm us that it is derived from Cullach. The recognised form amongst Irish writers of the present day is Mac Con Uladh—"The Son of the Hound of Ulster." McAnnulla, McAnnally, and Menally in Ulster are forms of Mac Con-Uladh, as also is the McFarlane sept in Dumbarton, i.e., McInally.
