This is a very old post but I just ran across it today. Walter Green Hamner was also my great grandfather. In researching my ancestry, I believe his father was Isaac Hamner. Walter had four siblings--Jessie, Thomas, Arnett and Eva. He was married to Daisy Bell Hebert, and they had 7 children. If you have a copy of his obituary or any other documents or photos, I would love to have a copy for my records. Hope your ancestry search is going well.... thanks for any information you can provide.
