I am looking for any information about my great grandfather, who I know as William Malvetz. What I have been told is that he was born in Rome, Italy and his mother is Concetta Iacovone. There is no proof of a father, which is where it gets confusing. The rumor in our family is that Concetta had an affair with her sister, Loretta's husband, Domenico Malvezzi. I was also told that Concetta, William, Domenica & Loretta & their family all came over from Italy together. William changed his name from Mario Iacovone to William Malvetz as a part of his naturalization on Nov 24 1939.
I need help figuring out who is William/Mario's father. Any information will help!!
