You are if you can document it. Like the article says, “Cherokees are among the best documented people in the world”. All one has to do is look up names on the Dawes Roll. I can count on one hand the number of Cherokee “pure breeds” i have met in my life (like my grandfather’s mother… his dad was a Melungeon-Cherokee mix). Most are half or a quarter. The PRESIDENT of the Cherokee Nation, ironically, is only 3% Cherokee which is absurd. i would argue that people like him feed into this common myth among white folks with no documentable Cherokee lineage.
