I answered your original posting - however have done some more checking -- you might try Randon Acts of Genealogical Kindness --- http://www.raogk.org/californ4.htmhttp://www.raogk.org/californ4.htm There are several serving San Diego county.
And some "IF'S" If his wife was Betty White -- they had three children in Calif. -- Also Gordon had a sister Barbara apparently. this info from Calif. Births -- Email me for more info. I try not to post on living people. (you might find the children still living) Email address:Jet0616@aol.com
And on SSDI -- the last benefit for Gordon was paid to somewhere in Port Hueneme,(sp?) Ventura county, Ca. Do you know of any connection there? This is going backwards to find your information, but sometimes that is the place to start. Good Luck -Janet
