The original discussion of presidents led me to another geni discussion, “United States Presidents and Vice-Presidents,” which made it very simple to search each of the vice-presidents. There are 47 on the list, but 14 of them became president.
Using the pushpin method, which I learned after posting the original message on this discussion, I found 30 of the other 33 vice-presidents descended from Henry III, king of England (son of John Lackland).
Of these thirty, 11 are descended through Edward I, his daughter Elizabeth and her daughter Margaret. Another six are descended through Edward I, Edward II, Edward III, John of Gaunt and John Beaufort. Two more are descended through Edward I and his son Thomas. Two more are descended though Edward I and another son Edmund of Woodstock. Three more are descended through Edward I and his daughter Joan of Acre.
Five more are descended through Henry III’s son Edmund Crouchback and his son Henry. One is descended through Henry III’s daughter Beatrice, countess of Richmond.
Of the remaining three, that leaves Walter Mondale, who can be traced back to Richard II, duke of Normandy (William the Conqueror’s grandson); Elbridge Gerry, who has links similar to the first 31 presidents in the original posting, ascending to Louis VI of France; and Thomas Hendricks, whose lineage produces no royal connections so far found in geni.
