I haven't done the DNA test for this, but my mom has turned researching our ancestors into her hobby on Ancestry.com. She has uncovered something absurd like more than 35,000 sets of ancient great(n) grandparents. I've seen some of her results dating back to 800-900's AD. Tons of Kings & Queens from all the European nations, LOTS of Viking blood (half the names in the Vikings streaming series), a handful of actual Saints (Olga of Kiev & Vladimir the Great).
I read once where every living human on earth today that has even a drop of European ancestry is a direct descendent of Charlemagne, and sure enough, she linked us directly back to good ol' Holy Roman Emperor Chuck I.
