Mac GIOLLA PHÁDRAIG—IVM'Gillephadrick, M'Gillapatrick, M'Kilpatrick, MacGilpatrick, MacIlpatrick, MacIlfatrick, MacElfatrick, MacIlfederick, MacElfedrick, Gilpatrick, Kilpatrick, Kirkpatrick, Fitzpatrick; 'son of Giolla Phádraig' (servant of St. Patrick). The principal family of this name are the MacGillapatricks, or Fitzpatricks, of Ossory, who took their name from Giolla Phádraig, son of Donnchadh, lord of Ossory, in the 10th century. In early times they ruled over the entire of Co. Kilkenny and part of the present Leix, but after the Anglo-Norman invasion they were greatly encroached upon by the Butlers and other English settlers in Kilkenny, and their patrimony was limited to the barony of Upper Ossory. Branches of the family settled in Clare, Cavan, Leitrim, and other parts of Ireland. In 1541, Brian Mac Giolla Patrick was created Baron of Upper Ossory. There appears to have been also a Scottish family of this name.
