Doug, thanks - you really did help with that information by showing
So, I don't believe Gwendolyn was adopted but was a child of Betty's previous marriage at age 16!
The 1940 census show Ray and Betty the same age, 39, and Gwendolyn E McDonough at age 23 and single.
Connecting the dots, so to speak ... it seems Ray married for the first time at age 27...that Betty had married a McDonough at age 16 and had a daughter Gwen.Their ages in 1940 of 39 and 23 are indicative that Betty had Gwen around age 16.OR Betty married someone else at age 16 and Gwen married a McDonough, and either was widowed or divorced before 1940 and moved in with Ray and Betty.
Just today another researcher found Ray Stewart's memorial on Findagrave showing that he was buried in California. So, I know where Ray is buried - BUT cannot find Betty or Gwen in California, Missouri or Tennessee.
Again, thanks so much for your help - it was a big piece of the puzzle.
