History of the Leonard name

In Ireland Leonard mostly disguises Gaelic originals rather than the continental saint's name. The chief source is Mac Giolla Fhinnéin, son of the devotee of St Finnian, a sept of the Fermanagh and Donegal borderland ranked among the chiefs of Lough Erne; the same Irish name was also anglicised MacAlinion. Other families rendered Leonard include Ó Leannáin of Fermanagh, erenaghs of Lisgoole, and Ó Lonáin of Connacht, so bearers in different counties may have entirely separate ancestries. The name is found today throughout Ireland, with its old northern heartland still well represented, and it travelled widely with emigration to Britain and America.
