They were saying about 50 years ago that 25% of all white Europeans could trace their lineage back to Charlemagne. It does appear that the higher ups did have more rights than others.
The pertinant right here being ius primae noctis - nudge nudge, wink wink.
They say 100% of all people if European descent, which also includes black Americans too since probably all black Americans are part white (excluding recent immigrants). Also, at a certain point in the past, all people alive then who have descendants today, are the acestors of everyone alive today (if I said it correctly). https://www.theguardian.com/science/commentisfree/2015/may/24/business-genetic-ancestry-charlemagne-adam-rutherford
trace their lineage back to Charlemagne.
Ex wife taught at a french private school, once a year the kids would bring their lineage and yes, about 1/3 of them went back to Charlemagne
All Europeans are descended from Charlemagne. The math pretty much demands it.
Each previous generation doubles, so assuming 3 generations per century, I have a million ancestors by the 1300s.
That was more than the population of Italy at the time.
If someone on the same continent in the 800s left any ancestors at all, then you are one of them. Guaranteed.
