Brophy

Brophy is an Irish surname of ancient origin, which is derived from the Irish "Uí Bhróithe" or "Ó Bróithe" septs that were located mostly around Ballybrophy, Laois, and in counties Carlow and Kilkenny. It is among Europe’s earliest true hereditary surnames, traceable to a 9th-century Ossorian ancestor and still geographically rooted in the same region more than a millennium later.
