Ó Ruanaidh, Rooney


Rooney is an Irish surname, an Anglicized form of the Gaelic Ó Ruanaidh meaning "descendent of Ruanaidh".

Variants of the name Rooney include O'Rooneen, Rooneen, Ruineen, Runian, Roonian and Roonien. These names are the anglicized forms of the Gaelic O'Ruanaidh Sept name. In modern Ireland this name is seldom if ever found with the prefix 'O' to which it is entitled, since it is O'Ruanaidh in Irish.
