I agree Terry. What's interesting is how my autosomal test is changing as services like 23andMe update their databases. Before the recent change, I had 5% Asian DNA and after it, I have less than 2% and there is more than 5% that is unassigned. I have ancestors who have said in the Congressional Record that they have Native American DNA and have since unearthed that both of my grandmother's parents (my great grandparents) being former slaves of Cherokee citizens and clearly with mixed blood.

As technology advances, I'm sure the picture will become clearer and clearer.
