It only costs about $100 and takes a few weeks.
I have a BIL from Oklahoma roots. Always made claims of Native American blood, which I understand is more common in the claim than in the fact.
Anyway he did his DNA, learned he has zero-zip-nada NA DNA.
My son took two different DNA tests. The first one was pretty damned accurate. The second showed 1% Native American. I would love to know where that came from. My husband's paternal grandparents were from Poland and his maternal grandparents were French Canadian. My family is 100% Italian.
