Straight from the horse’s mouth?
……… in which Dr. John Ashdown-Hill, who located the mtDNA match, tells nerdalicious what these findings really mean, not what the Cairo brigade (eg Hicks, Dan Jones and their acolytes) are already twisting them to mean:
1) Given that Richard III is only four generations down from Edward III, whilst the Somerset samples are about twenty down, they are about five times as likely to contain the “milkman”‘s DNA. In the interview, he even mentions the John of Gaunt – John Beaufort “connection” as a possibility for the broken link, which would substitute the (mere gentleman) Sir Hugh Swynford for Gaunt.
2) One of the live Somerset “cousins”, descended from the 5th Duke of Beaufort, doesn’t match the others, suggesting that the broken link could be quite recent, as well as the extra one this shows.
