I’m a genealogist who works with DNA as well as conventional research sources. We see this all the time. The Stormfront guys who test to prove they’re all Aryan who turn out to have a great-grandparent who was clearly Jewish. The “Cherokee Princess” descendants who find no Native autosomal DNA but rather 1-9% Sub-Saharan African.
If you are white and your ancestors lived in the southeast of the U.S. for longer than one generation, don’t do DNA testing unless you’re OK with possibly finding out that you have at least a few percentage points of SSA in your genome.
On the plus side, many people are thrilled to learn new facts about their family history and will embrace even the historically painful truths, because they are true.
