The Irish surname Brophy is an anglicized form of the Gaelic "O'Broithe", the prefix "O" denoting descendant of, plus the personal name "Broth". The surname is widespread in counties Laois and Kilkenny. According to the "Census" of 1659, Brophy was one of the principal names in five baronies of Queen's County (Laois), and in five of Co. Kilkenny. In Clandonagh it is perpetuated in the well known Co. Laois place name Ballybrophy. One Bridget Brophy, aged 25 yrs., a famine emigrant, sailed from Liverpool aboard the "England" bound for New York on May 26th 1846. Daniel Brophy of Castlecomer, Co. Kilkenny, three times mayor of Ballarat, Australia, was a well known public figure there in the 1870's.
