Lauraine, I checked familysearch and agree with Kathy that she died in San Francisco but could find no burial site listed. You might like to know that San Francisco has had no burial grounds for some time, most of the early dead and those who have died more recently are buried in graveyards outside the city, Colma being where most people end up. (Provides more room for the living in a crowded peninsula city.) The Presidio for military and the Columbarium on Geary Ave. are exceptions, the former being quite large.
Good luck to you, my friend!
