William Gagiano - William Gagiano

This might be a clue, at least as regards his more remote origins.

Gagliano is the name of a famous family of Italian luthiers from Naples, dating back to the early 18th century. The Gagliano dynasty - particularly Alessandro, Nicolò I and Gennaro - are considered the high point of Neapolitan violin making. There are as many as eighteen Gagliano violin makers known worldwide today. (Wikipedia)

You might want to do some checking around using that spelling.
