Charles, I am Thomas J Caldwell's GGGrandaughter. I will tell you what I have: He married Jenny Gist, their son, my GGrandpa, Andrew Jackson Caldwell, my Grandmother is his daughter Rilla Bell, my Dad is her son Raymond Ferguson. I have his service record from the Civil War. The highlight of his service record is he was a prisoner at Camp Morton Indiana on June 1862. He was captured on Feb 16th 1862. I have a note here that he was on a census record some time after the war. He apparently survived the ordeal. There is also a page that indicates he was not present for muster roll in 1864. After the prison ordeal I don't I would show up either. If you have any more questions let me know. I wish I had more information. Karen Ferguson Roach.
