I don't know if we can be of any help to you but my family have direct ties to a Robert Bratton who seems to have come from the western part of North Carolina. I have been looking for more on his parents because there seems to be some discrepancy in my information, but it would appear that his daughter Rachel was part cherrokee indian. Her picture sure shows that she is.
Rachel is my 4th great grand mother and was born in Tennessee. If I can help you I would be glad to do so and any information you have that might help me would be greatly appreciated.
