My name is Tracy Silvas, my father's name is Sam Silvas. My grandfather's name was Alfred Silvas, he had a sister Ramona and a brother Salvador and there may be more brothers. My grandfather added the "s" at the end of Silva, but I don't know when. I know that I have lots of cousins with the last name Silva without the "s" at the end. My Grandfather was from Ysleta Texas. Any relatives out there? We are from Lincoln Ca.
