George,
I don't know much about the Creole people. However I'm sure that quite a few East Tenn. Melungeons fought in the Civil War. Being centered around Hancock County they may have been some on both the Confederate and Union side. They were also citizens of the county but I believe the racial mixture is of some debate. Most think it being Tri-Racial, mostly white with black and some Indian (Cherokee) mixture.
Regards, James.
