Looking for info and relatives on Great Grandparents. Manual Perry Silva and Marianna Avila. They lived in Newark, California. They both came over from the Azores. It is rumored that my Manual was married to Marianna's sister and she died without childrena and Marianna was then sent over to marry him. I really need help I am stuck at this point. My Grandfather was Anthony Silva. His children are Walt, Howard, Jack, Bobby, Sandy, and my mom Pat.
