I am not sure that is right about the DNA test--I have documented ancestors, with birth records showing descent, like my 9th great grandfather, Amadohiyi Pigeon of Tellico Moytoy:
https://en.wikipedia.org/wiki/Moytoy_of_Tellico
that is authenticated by legal records, as well as family lore--
but my DNA test did not show this, although it showed the area of the country that was the Cherokee nation as "genetic communities". It also identified cousins that have the same Cherokee ancestors as genetic matches.
So I am not sure how precise those tests are, so far?
