I'm impressed with your research. It seems like my family has a similar story, and it is sure hard to track down. I think there was definitely an Indian trader in my family, and they passed through north Alabama. I can't tell you what a shock it was when I heard names like "Doublehead" and "Attakullakulla" in the same breath with talk of my family. I think I ran across something about a John Ross in the South Carolina Indian Affairs documents. I will try to remember to post it later. We should compare notes.
