Hi Ann

Thanks for the informative reply. I intend to have the mtDNA test done also
and will probably go with Oxford. The reason I went with the NA first is
because my mtDNA line is also my documented NA line. I have records of my
grandmother (mother's mother) Dawes Commission records for her fathers
family who married into the Chickasaws before 1800. They removed to Indian
Territory(OK)during the removel 1832-1845. My grandmother's mother came to
Indian from TN in 1901 with her mother and about 25 other family members to
register as Mississippi Choctaw. They were denied for a lack of written
proof. As you can see much of my maternal line is or appears to be of mixed
blood NA.
Vie Bacon, b 1904 New Born rolls Chickasaw Grandmother maternal
Lucy Sims b 1880 TN appl'd MS Choctaw Grgrandmother
Sarah Singleton b 1838 TN " " Gggrandmother
Louisa Jane Hickman b.1813 Choctaw?? Ggggrandmother

Thanks again for the advice!
Linda Davis
