Devaney

Devaney, Devany, and O'Devaney, is a surname derived from the Irish Ó/Mac Duibheamhna, meaning "descendants/son of Dubheamhna". They are cited by O'Dugan as being chiefs of Kinelawley in the over-kingdom of Ulaid, now known as Clanawley in present-day County Down, Northern Ireland.

Ó Duibheamhna derives from a personal name based on the Irish word dubh, meaning "black", and the genitive of Eamhain, the Irish name for Navan fort located in County Armagh, Northern Ireland. It was the former capital of Ulaid. Another family/clan was based in the diocese of Raphoe, in Donegal, Republic of Ireland, and may be a distinct branch.

The surname was considered by Woulfe in 1923 as being obsolete or changed into some other English or Irish form.
