Though genetic genealogy has been around for more than a decade, the sight of celebrities swabbing their cheeks on TV shows like Who Do You Think You Are? and Finding Your Roots has undoubtedly contributed to its growing popularity. But if you're new to it - and sometimes even if you're not - it can be a little confusing. For that reason, I've been sharing a series of "DNA Stories" videos featuring the experiences of real life people and how they've used DNA testing to tackle their personal history mysteries (see below for links if you've missed them). Well, now it's my turn.

As a Smolenyak who married another Smolenyak (and a professional genealogist to boot), I am constantly asked whether I married my cousin. Check out the video above to see how I used Y-DNA tests to solve this riddle.
