The Francis that you speak about, does she have a sister, Matha or Mary? I think this is the same linage as mine.
I have some information on this group before 1830's and alot from then to the present.
I live in the Armuchee ga area, which is not far from Sugar Valley.
Do you have a time frame for when Francis would have lived in the Tenn area? I have been looking for her brother William's marriage to Susan Jane Jones, who was a full blood Cherokee. I have pictures of her, and William but nothing further back.
Look forward to hearing from all with any lineage.
