Rooney

Rooney is an Irish surname anglicized from Ó Ruanaidh, meaning 'descendant of Ruanaidh,' a personal name derived from Old Irish ruanaidh meaning 'champion' or 'hero.' As a given name it carries the plucky energy of an Irish surname that has been promoted to first-name status.

Rooney is a name with natural bounce. The double-O in the middle gives it a warm, rolling sound, and the Irish surname heritage adds just enough substance to keep it from feeling lightweight. It gained some cultural traction as a given name — Rooney Mara, the actress, is a well-known bearer — which moved it into the mainstream consciousness without making it feel used-up. For pets, Rooney suits a cheerful, slightly goofy dog who is deeply enthusiastic about life: always in motion, always the friendliest presence in any room.
