sentences:  It is unusual that so many in the Sorentine surroundings (and Naples) were already using the Gargiulo surname in 1600, since ordinary people in other parts of Europe had not yet started using surnames at this early time.However, Romans commonly did use 2 names, and even 3, which could help explain the early use of 2 and 3 names in southern Italy.However, so far no connection between Gargiulo and Gargilius has been documented.
