The surname was originally a nickname given to a person born on that day, reflecting a common Italian tradition of naming children after feast days or saints.Etymology and OriginsThe name Santoro belongs to a family of Italian surnames derived from the word santo (“saint”). Related surnames include De Santis, Santini, and Santo. In other Romance languages, equivalent surnames are Santos (Spanish) and Santo (Spanish). The Latin root sanctus means “holy” or “consecrated,” and many Italian surnames with the Sant- prefix have religious connotations.Notable BearersThe surname Santoro has been borne by many notable individuals across different fields.
