The surname O'Cormacan was first found in Galway (Irish: Gaillimh) part of the province of Connacht, located on the west coast of the Island, where they held a family seat as Chiefs of the Clan O'Cormacan. Irish history was greatly influenced by the Norman invasion of 1172, and thereafter, the surnames of Irish Gaelic clanns and septs and many of the Norman families became almost indistinguishable. This family name was found later in Thomond, Roscommon and Down.
