I am trying to search my great grandfater who came to the US in 1913. I recently found his Naturalization paperwork and it states he was on the San Guglielmo departing from Naples Italy on December 3rd 1913 and arriving in New York on December 15th 1913. I looked at the manifest and he is not listed at all.
I have been told numerous stories that he was a stowaway, or a crew member of the ship. He also changed his name from "Antonio Ayanto" (which he is buried under), to "Antonio Azzanti" and "Anthony Azzante". I am just looking for the last few peices of information and any help is appreciated.
