That's not how population genetics work.

Almost every European-descended person has ancestry from Kings and peasants alike. Even the very recent Oliver Cromwell has way more than 20k living descendants in the UK. If you have any substantial English ancestry, there is a Plantagenet somewhere in your family tree to a mathematical certainty.

On the continent, and in other aristocratic societies like Dynastic-era China, things are much the same. If Qin Shihuang's progeny weren't all put to the sword, just about every Han Chinese person is descended from Qin Shihuang.

Read about the "identical ancestors point". Past that point, every individual alive is either: (1) ancestor of everyone alive today, or (2) ancestor of no one alive today.

I'm definitely aware of this.

This is a very very far stretch from saying your family was royalty. Though i do guess you are technically correct. Forgive me, your highness. lol

Let me add that you've delineated a technicality with no real consequence to my argument. If anything supporting my argument by suggesting that makes anyone proper royalty.

		> If anything supporting my argument by suggesting that makes anyone proper royalty. This could potentially be a good argument for more democratic systems. My grandmother was very proud of the fact that we were descendants of King James (one of them, I couldn't tell you which one, probably the one that abdicated!) What she didn't understand is that something similar was true of almost everyone she knew.
