Origin of the Name Crowley
The ancient history of the name Crowley
was found in the allfamilycrests.com archives. Crowley is a name of Irish origin from the Gaelic O'Cruadhlaoich sept.
A sept or clan is a collective term describing a group of persons whose immediate ancestors bore a common surname and inhabited the same territory. Irish septs and clans that are related often belong to even larger groups, sometimes called tribes.
The history of the Crowley sept presents an example of a junior branch of a sept which migrated to a distant Province, prospering and multiplying in its new territory, while the main sept dwindled and almost disappeared from its original homeland. The sept of O'Crowley began as a branch of the MacDermots of Moylurg in County Roscommon. Their eponymous ancestor was one Cruadhlaoch, meaning 'hard hero', hence the Irish form of the surname O'Cruadhlaoich. The branch referred to above settled in the territory near Dunmanway, County Cork, and in due course became a distinct sept with a recognized Chief residing at Kilshallow.
The Crowley coat of arms came into existence centuries ago. The process of creating coats of arms (also often called family crests) began in the eleventh century although a form of Proto-Heraldry may have existed in some countries prior to this. The new art of Heraldry made it possible for families and even individual family members to have their very own coat of arms, including all Crowley descendants.
