McNulty Surname

Strange as it may seem, the McNulty surname derives from the MacDonlevys/Dunleavys who fled early Ulster (primarily County Down) after their defeat by the Anglo-Normans in 1177. Those Dunleavys who migrated westward to Donegal became known as Ultach because they came from Ulster as it was then. The Four Masters have recorded two distinguished McDonlevy physicians to the O’Donnells of Donegal, namely, Paul Ultach in 1395 and Owen Ultach in 1586. Their descendants assumed the name, Mac an Ultaigh, son of the Ulsterman, now Anglicized as McNulty.
