O' Crowley, O' Cruadhlaoich


The sept of O’ Crowley began as an offshoot of the McDermott’s in County Roscommon. Branches settled in Dunmanway in County Cork – and are still much identified with that area. Another small branch of the Crowley family is also found in Connacht. The name is derived from the Words Cruadh – meaning hard, and Laoch – meaning hero.
