COSTELLO Family History

Costello is an Irish surname found in Mayo. Costello is also a rare Italian surname that does not derive from Irish. It is more commonly found as Costelli, sometimes Costella. Costello, Costelli, and Costella are usually found as Italian surnames in northern Italy. In other cases, "Costello" was adopted as a stage name or alias by people of Italian descent who had a different surname, such as Costa or Castiglia.
