My great grandfather was named Joseph (Giuseppe) Vetrano, and came from Naples, or the area surrounding Naples. I believe he was born in 1888 or thereabouts. He was a bicycle racer of some renoun before he emigrated to the US in the early 20th century. I do not know whether or not he had any siblings.
He settled in NY (I believe he worked in a butcher shop) and married my great grandmother, Antoinette Verdarosa. They had four children - Leo (Liberato, my grandfather), Theresa, Concetta, and Vincent.
I don't even know where to begin to try to research things in Italy, as I'm quite new at this!
