The Duchess of Brittany was Margaret de Foix-Grailly, a cousin of Jean de Foix. She financed part of Henry’s eventual invasion of England. As noted above, in 1462 Henry VI’s wife Marguerite d’Anjou sought help from the French King to recover the throne for her husband. If she succeeded, then she undertook that either Jasper Tudor or Jean de Foix would be appointed governor to effect the handover of Calais to King Louis. One has to assume that these two were known to each other, and possibly friends.
All of the foregoing produced a strong set of relationships between the de Foix family and the Kings of England.
Also dying at Bosworth Field was Richard III’s Secretary of State, John Kendall. First mention of John Kendall seems to be a reference to him in a letter patent in 1474 as the Secretary to Richard, Duke of Gloucester.
Then in 1478 he was the signatory on a letter from Richard to Sir William Stonor of Oxfordshire. Kendall was in 1480 granted £80 during the life of the attainted Sir William Stonor’s mother. She was Jane de la Pole, the illegitimate daughter of William de la Pole, Duke of Suffolk (See Tree 2). De la Pole’s wife was Alice Chaucer, and her father was Thomas Chaucer, and it was he that had the wardship of the young Thomas Stoner, father to William and who married Jane as above. The Stonors and Chaucers were Oxfordshire neighbours and had maintained strong family relations.
