Our Sanders came to Oklahoma by way of Arkansas, and before that Indiana. After coming to OK, they lived in the eastern part of the state. We do have 2 other lines of Sanders in the family that I have very little info. One line came from Missiouri. The 3rd line of Sanders is still a mystery to me. One man was married to one of our Cherokee Indian ancestors. But I have absolutely nothing on him or his family. I don't know if he was Indian too or not.
Good luck on your research.
