Finding an obituary in Los Angeles Co. is a great challenge because of the number of towns and cities and an incomplete listing of where old newspaper copies are stored.
The Los Angeles County Public Library does do an obituary search (Los Angeles City Library does not), www.colapublib.org/contactus/ . Successful Searching!
