Re: odd question
You might try to look up their obituarys. Alot of libraries have micro filmed copies of old newspapers. You would have to know the town where they lived at the time of their death. I found on the social security death index
Wilfred Causey born 10 Dec 1928 died Aug 1968 last residence not listed but I would try Houston. John L. Bassett born 28 Dec. 1917 died 3 May 1989 last residence Olivehurst CA. Then you might try google.com and type in Standard Form 180 to find out how to get their military records.
