Hi Ken, Those two obituary volunteers are incorrect. San Joaquin Co. does not have any obituary volunteers at this time.
Contact the Stockton-San Joaquin County Public Library, www.stockton.lib.ca.us/ .
If they don't have obituaries that old, contact the California State Library, library.ca.gov/calhist/genealogy.html . They have the largest newspaper collection in the state. However, they don't have the staff to do the searching. They will send you a list of researchers in their area who look up obituaries for a fee.Successful Searching!
