Finding William's obituary would be a big help to you. I'd post a message in the Arizona, Maricopa County Message Board asking how to find his death date. Then you can search for his obituary (if one was published).
You might want to pursue Orissa Olson's obituary too. You can post a query on how to find obituaries in the Arizona, Gila Co. Message Board. Successful Searching!
