Traditionally, Irish family names are taken from the heads of tribes, or from some illustrious warrior, and are usually prefixed by "O", as above, or "Mac", denoting "son of". The O'Canavans were hereditary physicians to the O'Flahertys of Lemonfield (County Galway); it was (and is) primarily a County Galway name.
