I am a descendant of Nancy Thornsberry (through daughter Judith/Judah). In our family history we have always understood Nancy to be Cherokee. We have a tin-type of either Nancy or perhaps Judith and she looks strikingly native American. In the photo she is wearing a pioneer type dress with a bead necklace that looks Indian-like. I do not have immediate access to this picture, but will try to obtain a digital image of it to post on the web in the future.
