I can tell you about a Vincent D'Ambrosio of Chicago who was my great-uncle. I didn't think he had any children. He was born in 1899, died in 1927. I hope he was not the Vincent you are looking for, as he was rather infamous -- a gangster who was part of the gang that challenged Al Capone. I have lots of bio on him if he is the one you are looking for. He was my grandfather's brother.
