Origin Of The Name: Chaomhánach

The surname Kavanagh or Cavanaugh and the other variants of the name are derived from the Irish Gaelic name Caomhánach, which means 'a student or follower of St. Caomhan' and was first used by Domhnall, eldest son of the 12th century King of Leinster Diarmait mac Murchada (Dermot MacMurrough).

Domhnall was fostered for his training and education at the monastery of St. Caomhan at which is now known as Kilcavan in the Barony of Gorey, County Wexford. He became known as Caomhánach, distinguishing him from the other sons of Diarmait.
