Bad information often appears on headstones, as people who read this post will attest. Also, I would strongly advise against accepting that or the information someone posted on a website at face value. You need to see a copy of the actual application and see what might be included in those papers.

Thomas Mackey or McKey was a resident of Centre Star, Lauderdale County AL. He enlisted near his home in Co. "G", 11th Alabama Cavalry Regt. I see no possible connection to Thomas McNatt of Franklin County AL.
