Rachel Weston is my great great great grandmother and I have always been wondered if that story was true. I come by her through my fathers mother . The most I have been able to find researching is that they were in augusta, Virginia which is near lynchburg. I live in virginia now (grew up in iowa) and unfortunately can not track any evidence that she was indeed an indian. I actually show is was buried at the winslow cemetary as well as Thomas . I, in fact, just had a dna test thru www.23andme.com
and they found I have no indian genomes. .01% west african... but no indian. so sad.. was really wanting her to be a great story.
let me know if you find out any different.
