I found a casualty list of all military personnel and civilians who were killed at Pearl Harbor. These were the only two named Thornton. At least it will put that rumor to rest. THORNTON Cecil Howard S2c USN USS OKLAHOMA THORNTON George Hayward GM3c USN USS ARIZONA You might have to sit on this until the 1940 census becomes available. It's strange that there doesn't seem to be any Social Security record for him. Joan in Illinois
