According to one historical research center, the Irish surname Coyle is an anglicized form of the Irish name Mac Giolla Chomhgaill, literally translated as " devotee of St. Comgal". This surname originated in Ulster and is found principally in the counties of Donegal, and Tyrone and in north Connacht. Another rarer form of the name Mac Ilhoyle/Mac Ilchole, can be found in the barony of Kilmacrenan and the parish of Meeragh, the homeland of the sept. The family is commemorated by the placename Ballymacool in the barony of Kilmacrenan. The Coyles of north Connacht are thought to belong to a separate sept. or perhaps, a branch of the Ulster sept.
