Ok Ted, This is really BIG ! I finally found a pic of my great grandmother and your great grandmother (of same person) Adelaide Cornelia Tune. I got this pic from the late Melvin Harris' son Michael.
I am quiet certain the little boy on the left of her (as we look at pic) with little white hat on MUST be Dewy. I also got a great pic of Dewy in service uniform in TX in my tree. It also is the only pic I have located of him. I will try to send both to you. If I am not able to attach them then go to my Family Tree Janice Oliver or
gabbyjan@gmail.com to see pics. It is a public tree.
I Hope you enjoy meeting our Great Grandmother as much as I did! lol Janice Oliver
