Doyle

Doyle is a surname of Irish origin. The name is a back-formation from O'Doyle, which is an Anglicisation of the Irish Ó Dubhghaill, meaning "descendant of Dubhghall". There is another possible etymology: the Anglo-Norman surname D'Oyley with agglutination of the French article de. It means 'from Ouilly', the name of a knight who originated from one of the places named Ouilly in Normandy, such as Ouilly-le-Tesson, Ouilly-le-Vicomte, etc. The relationship with the family D'Oyly is unknown.
