Ó Conraoi / Mac Conraoi
A Connacht surname from the great families of Roscommon and Galway
Conroy — Ó Conraoi — is a significant Connacht surname, concentrated in Roscommon and east Galway. The name means hound of the plain and the family was associated with the O'Conor kings of Connacht.
Conroy — Ó Conraoi in Gaelic — is primarily a Connacht surname, concentrated in Counties Roscommon, east Galway, and south Mayo. The name means hound of the plain — con being the Irish for hound (appearing in many Irish names) and raoi meaning plain or field. The Ó Conraoi were historically connected to the Uí Briúin Aí, one of the royal families of Connacht, and the surname appears in early Irish genealogical records as a family of some standing in the Roscommon area.
A separate Mac Conraoi family existed in Clare, and there is also a Munster presence that may represent a distinct family of the same name. As with many Irish surnames, the question of single or multiple origins is unresolved.
The Conroys of Roscommon were historically associated with the O'Conor kings — the Connacht royal family who provided the last High Kings of Ireland. The Conroys appear as part of the network of families dependent on or connected to the O'Conor dynasty, which is why the name clusters in the same geographic area as the O'Conor heartland around Roscommon town and Clonalis.
Roscommon was one of the worst-affected counties in the Famine. The county's population fell by more than a third between 1841 and 1851. Conroy families emigrated in large numbers, principally to New York and the industrial cities of England. Griffith's Valuation shows Conroy most densely distributed in the Roscommon and Castlerea registration districts.
