At the moment this surname only exists near Venice, at ODERZO. In fact the surname is probably from Southern Italy. It could come from the village of CAPOSELE, near AVELLINO, not very far from NAPLES. It looks like a sicilian surname SCUTO. now more common around Italy. The suffixe "-ese" very often indicates that the surname has a locative origin. But unfortunately i haven't found aout any place in Italy called Scuto.
