So what, I am descended from John Lackland as well. So is just about everyone else in this country whose ancestors come from Albion. The only trick is finding the paper trail that gets your family tree back to the old country. I’ll bet that they are all related to Charlemagne too, even Martin Van Buren would probably make that cut.

Anyone related to King John is related to Charlemagne, since John was himself descended from Charlemagne.

I have an unproved lineage back to John myself (it was a 'Darth Vader moment' in my genealogical research given his villainous reputation), and just in the past week I've unearthed documentation that states that one of my wife's ancestors is a descendant of King John. I still need to dig up the particulars, but like you said, it's almost a sure thing for anyone of European descent.

Charlemagne who's family killed the true royal line (the Morovingian king) and as "mayors of the castle" were usurpers. And aren't we all descended from "Lucy" according to National Geographic?
