John de la Pole born in 1442 was the only son of William de la Pole, earl and then duke of Norfolk and Alice Chaucer, granddaughter of the poet Geoffrey Chaucer. William de la Pole was Henry VI’s key adviser during the 1440s. It was he who arranged the marriage between Henry VI and Margaret of Anjou in a bid to bring the Hundred Years War to an end, on Henry’s orders it should be added – it didn’t end the war with the French and it didn’t make William popular with the English who blamed him for a French bride who had no dowry but who had cost England large areas of France: Maine and Anjou. It probably didn’t help that he was descended from a Hull wool merchant rather than being tied by blood to the ruling families.

John de la Pole is technically Margaret Beaufort’s first husband…
