Heally, Heeley, Hely, O’ Healihy, O’ Healy, Ó hÉilidhe
The Healys in Ireland are descended from two different clans, the Ó hÉilídhe, from the Gaelic “éilídhe” meaning ‘claimant’, and the Ó hÉaladaighthe, from the Gaelic “ealadhach” meaning ‘ingenious’. The former clan’s territory was the Barony of Tirerril in County Sligo in the province of Connacht. The Ó hÉaladaighthe, meanwhile, were from Cork in the southern province of Munster. The name is now the forty eighth most common in Ireland, and remains predominant in its original homelands of Sligo and Cork.
