Go ahead and do it, but be prepared for what might be revealed. Are you aware that a lot of folks claimed native american ancestry to conceal their black ancestry, and to explain a darker complexion? Many Americans are a mixture of European, Native American and African, especially those whose ancestry on these shores dates back to the 1600s and 1700s, early 1800s. There was just so much mixing going on then, and there was, and still is, such a high price to be paid for claiming one's black ancestry.
