There are no cemeteries in San Francisco unless he/she was military and then they would be buried at the Presidero. . All other bodies were moved out of SF a long time ago. Most went to various cemeteries in Daly City which is right below(South) of SF. Check those cemeteries. There are many. IF Jewish then they would be in the Jewish Cemetery. Just search Daly City Cemeteries CA> Hope this helps. You can always call them too once you have the numbers
