Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name Kavanaugh is Caomhanach, an adjective denoting association with St. Caomhan. The first Kavanagh, Donal, the son of Dermot MacMurrough, was fostered by a successor of this saint.

Early Origins of the Kavanaugh family

The surname Kavanaugh was first found in County Carlow (Irish: Cheatharlach) a small landlocked area located in the province of Leinster in the South East of Ireland, where they held a family seat from very ancient times. The Kavanaghs (Cavanaghs) were descended from the MacMorough stem and were Lords of Leinster.

Donell, son of Dermot MacMurrough acquired the name Caomhanach, or Cavanagh. His sister Eva married Strongbow, Earl of Pembroke, the leader of the English invasion of Ireland. 1
