The surname O'Canavan 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 hereditary physicians to the O'Flahertys. Traditionally, this great sept is descended through the Fihillys from Muredach Maolleathan the 16th Christian King of Connacht. 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.
