The thing about me is that I’m Jewish. It’s not the only thing about me. I’m also 5 feet 11 inches tall, a glasses wearer and into bicycling. But most people who know me probably wouldn’t be surprised to learn that most of my ancestors lived in shtetls in Eastern Europe.
So, it wasn’t too surprising when I sent off nine DNA samples to three different DNA companies under a variety of fake names, and the results indicated that I’m super-duper Ashkenazi Jewish. (Ashkenazim are Jews who trace their ancestry back to Yiddish-speaking populations inhabiting the region between France and Russia.)
Here’s what was a bit surprising, though: None of the companies — AncestryDNA, 23andMe and National Geographic, which works with a testing company called Helix — could agree on just how Ashkenazi I am. [How Do DNA Ancestry Tests Really Work?]
