While I would love to think this was possible, I looked at the tree you referenced and I do not believe so. This person only has a single source for Tommy (Steve's father), the 1940 census. The remainder of the family information was copied from another Ancestry tree. It is very disappointing, but family trees have become almost unreliable (in my opinion) as far as research tools because so many people blindly click on a leaf and think it is always going to be accurate. Without verifying the data you are adding, you are not only introducing bad data to your tree...but also providing that information publicly for others to copy. The top hit in family trees for Tommy is a tree that lists him as being born in North Carolina. The source for this is a prison record for Tommy out of WA. If you look at the record, while the names match, the ages don't. Further, Tommy's parents were in OK and surrounding areas both before and after his birth, so it is unlikely that he would be born in NC, and all his siblings and parents only recorded in OK and MO. (Sorry for over explaining...I turn into a genealogist after midnight when I run out of shoe prints to search).
I was feeling overly optimistic tonight, so I tried putting in a records request with the VA. In 800 characters (including spaces) or less, I begged as eloquently as possible for just an idea whether he was "active duty" immediately before his discharge, or some other status. Not being next of kin or having an obituary, chances are I will not succeed, but my new motto is You Can't Fail if you Don't Try! Considering my failure rate recently...I am due a big win. So fingers crossed!!!
