My name is Barbara. I have been searching for info on My grandmother as well and I'm pretty positive we are talking about the same people :-)
My grandmother, Ethel Christine Haygood Moore, was Married to my "Grandfather" Jimmie Walters who was a county commissioner in Johnson County, Tx. They adopted my father in 1952. His name was Robert "Bob" Eugene Walters. He left home and joined the Navy when he was 16 or 17. At some point he lost contact or had limited contact with my Grandmother. When I was 11, I found a letter from her to my father. I decided to write to her myself.
So, from that point, I do have letters from her and pictures of her and Bob (I call him my grandfather, not Jimmie, I hope that is okay.)
I will also continue looking and hope to help in any way I can.
