His parents will be listed on his death certificate IF the Informant at time of death knew that info.
However, I can't find him any a 1940 Census or where/when he died? Do you know his mother's maiden name or his middle name?
I searched through the following cemetery indexes but didn't find him: US GenWeb Tombstones, www.usgwtombstones.org/california/sacramento.html California Genealogy, www.rootsweb.ancestry.com/~cagha/cemeteries Sacramento County Genealogy, http://freepages.genealogy.rootsweb.ancestry.com/~npmelton/http://freepages.genealogy.rootsweb.ancestry.com/~npmelton/
Not all of the cemeteries are indexed. For some of the cemeteries you need to contact a particular person. I did not do this.
I did find his marriage to Mabel. Arthur C. Booth Married: June 23, 1910, Jackson Co. Mabel E. Bigham Source: Oregon State Archives, http://genealogy.state.or.us/http://genealogy.state.or.us/
