I'm trying to find a birth record for my grandfather, Erom T. Joyce who was born on 2 Jan 1899 (there's a possibility he was born in 1900). His parents were Juanita Fournier and Walter Joyce. (They also had another son, Lawrence "Larry", who was younger than Erom. Larry was dead by 1910 and I'm unable to find his birth OR death record.)On Erom's RR records it states that he was born in "San Francisco, San Mateo County".I've been told that none of San Francisco is in San Mateo Co. ---- but when I put San Francisco into the Rootsweb Town Search it comes up saying that S.F. is in S.F. County AND San Mateo County! I'm confused and not sure where to look! Any help will be greatly appreciated!
