I can't remember if we covered JW's death I think you thought he died in California. There's a death index confirming that he did indeed die in Riverside County, California there are also online photos of his grave. Some California death certificates are available free to view on Family Search but certificates for Riverside County are not included at the moment. The death certificate may include information about his parents. The approx. year of birth 1844 matches the JWW from Georgia.
