I have read this article before, & not sure I buy into it..Royal /aristocratic families tended to marry others of the same station....the odd illegitimate liaison aside...those of us following certain lines, will find the same names cropping up over & over again..I would say that the majority of the peasantry, here in England, & in France, or wherever, never had any physical connection to the nobilty of the area in which they resided..It's true that down the centuries, the descendants of prominant families,..younger offspring, may have come down in the world ..It's also true that 2-3 hundred years ago, the younger sons of many aristocrats, emigrated to the New World..Many Americans today still have the records of their earlier illustrious forbears...Some ancestry is hard to track down because records were destroyed..But these fortunate Americans had theirs handed down..I know far far more Americans with Royal ancestry, than I do English..On a series of "Who do you think you Are", a TV presenter called Jeremy Paxman was taken back to the Middle Ages, & it was completely peasant stock..It's possible of course, that some lines on one side or other, were missing, & we didn't have the complete story....Also, for many centuries within Europe, most people remained within their own area, ., so the only chance for the mixing of this gene pool, would seem to be in more recent times..I would like to see more proof of this theory, before I'm ready to accept it..
