I can't really help you with any of your research, but, in reading it, all the surnames you listed are found in Lauderdale County, TN. They are seen here as early as the foundation of the County and before that in Crockett and Dyer Counties. Also, it seems that most of the people that formed the county here, came from Wake, Persons and Orange County, NC. I don't have any knowledge about them being Native American's or not, just what I have said here. I don't know if yours connect to them, but if you find some that dissapeared on the way to Arkansas, you might look here. If I can help with something, let me know and I will see what I can find for you. Good luck, Debbie Tillman
