From the Arizona Republic, 28 Nov 1942, section 2, page 5: "Oliver, Littleton H. - Funeral services at 10:00 am today in the Whitney Funeral Home Chapel. Burial in Greenwood." I went by Greenwood Cemetery to see if I could find any more info, but there is no marker on the grave. It's location is Block 41, Section 43, Plot 1. According to the death certificate, he lived at Schmid's Haven of Rest at the time of his death, but they don't exist anymore. But the funeral home is still around. Whitney & Murphy Funeral Home, 4800 E. Indian School Road, Phoenix, AZ 85018. Tel 602-840-5600. They may be able to give you some more info. Also, according to http://genealogy.az.gov, Littleton didn't have any children born in Arizona. Send me an e-mail at email@example.com if I can be of any help.
