For decades, I have been told that one of my great-grandmothers was half-Cherokee, making me at least 1/16th Native American. Recently, though, I sent a DNA sample to AncestryDNA, and these are the results — no Native Americans of any kind. I was also told that I have no Irish ancestors, and that’s not supported by the data, either. Here are the numbers that go with the map above.

The results do support a less precise estimate of my ethnicity: I’m an American mutt. No surprise there.
