Louis, dauphin de Viennois (future Louis XI) married Princess Margaret of Scots in 1436, when she was twelve and he a year older. She died, nine years later, without having borne him any children. He remarried to Charlotte of Savoy and had three surviving children by her – Anne de Beaujeu, St. Jeanne de Valois, duchesse d’Orléans and Charles VIII. Margaret was the eldest daughter of the King of Scots by Joan Beaufort, a granddaughter of John of Gaunt. Thus, any of her children would’ve had a very distant claim to the English throne. OTL, Anne de Beaujeu as regent supported Henry Tudor’s expedition to reclaim the crown of England, but here, the French kings would have their own distant claim. But, more to the point, Anne de Beaujeu’s regency after Louis’ death was plagued by civil strife with several of France’s dukes. Would an adult male heir (born in the late 1440s; Margaret survives whatever killed her OTL, but her previous children have either been female or stillborn) have made any difference? A marriage to Marie of Burgundy seems likely (especially if she’s still an only child), as a way of assuring that the Burgundian provinces return to French control. Or would Louis’ heir have indulged in the same plotting and scheming against his father that Louis himself had once indulged in?
