Genetics, hereditary factors, social privilege or something else? 'Great People" decended from just one woman
Queen Elizabeth, Lady Diana, almost all of the members of the royal families of Europe, George Washington, Thomas Jefferson, John Quincy Adams, Rosevelt, George W Bush, Churchill, Tenneson, and Bertrand Russel are all descended from one English Duchess. Her name was Kathryn Swinfeild and she was the mistress and then wife of Duke John of Galt (aka The King of Castille) and the mother of the Beauforts and some of the kings of England.
What do you think accounts for this?
