DEVANEY Family History
Recorded as Devaney, Devenny, and Devennie, this is an Irish surname. It is particularly associated with the province of Connacht, and East Ulster. It derives from the pre 10th century Old Gaelic name O'Duibheannaigh, meaning the descendant of the black bird. The Irish prefix of either "Mac", meaning son of, or O', male descendant of, gave rise at an early date to a group of fixed hereditary surnames of the patronymic type. These surnames originally signified membership of a clan, but with the passage of time came to identify membership of a "sept", or group of people all living in the same locality, all bearing the same surname, but not necessarily descended from a common ancestor.
