Crowley (surname)


The Irish surname Crowley was first found in Moylurg, in County Roscommon, where they started as a branch of the MacDermots. It is from Teige, a Prince of Moylurg, down to Cruadhlaoch that the line of descent for the Crowleys begins. A junior branch of the Crowley family also emerged and moved to the area of Dunmanway, in the west of County Cork. They eventually became a distinct sept with their chief at Kilshallow, thriving while their family of origin gradually decreased in number. The majority of the Crowley family came from the county of Cork, with three-quarters of the family originating from there.
The Irish "O Cruadhlaoich" or "Ua Cruadhlaoich", a Gaelic name meaning "descendant of the hard hero" or "descendant of the hardy warrior", was anglicised to "Crowley" or "O'Crowley".
Variants include Crawley, Crowly, O'Crowley, Croaley, Croawley, O'Crowly and many more.
