Show ContentsKelleher History, Family Crest & Coats of Arms

Irish surnames are linked to the long Gaelic heritage of the Island nation. The original Gaelic form of the name Kelleher is "O Ceileachair," which means "companion dear." 1 Another source claims the name means "wise, prudent." 2

Early Origins of the Kelleher family

The surname Kelleher was first found in County Clare (Irish: An Clár) located on the west coast of Ireland in the province of Munster, where they held a family seat from very ancient times. They "derive their sirname from Ceileachar, son of Donchuan, brother of Brian Borimhe [Boru], the 175th Monarch of Ireland. In the twelfth and even so late as the sixteenth century, the O'Kellehers were possessed of lands in Munster; but the pedigree of the family is, we fear, lost." 2 The oldest record of the family was of Donogh O'Kelleher, successor of St. Kieren of Siager (Bishop of Ossory) who died in 1048. MacLysaght noted that the family left their original habitat in County Clare in the 14th century and moved to County Cork. 3
