Kay, I didn't find Samuel & Sarah in the 1850 California Census. I did find that the 1850 census for Contra Costa, Santa Clara and San Francisco had been lost. I was told by a very nice lady at the Gen. Library that Santa Clara had a state census in 1852. We tried to locate the film at the library but couldn't find it. If there were in Santa Clara after 1850 maybe you can locate them in 1852. Sorry I wasn't able to help! Jackie CANAPA-L List Owner
