Comments : Tugdual or Thudual of Kermoysan was the second son of Yvon de Kermoysan. He was born some time between 1390 and 1400 in his father's manor at Goasmap, Goëlo, Brittany, France. He married Marie de Garancières, Lady of Macy, Villiers-the-Count and Croisy. He joined the dolphin' s army in 1421. Entered Orleans on May 4th, 1429 as part of the reinforcements that Dunois brought back to the city. Kermoysan bravely fought with Jeanne all during her Orleans campaign.. At the battle of Patay, Thudual fought valiantly under the command of The Constable, Arthur de Richemont.
Thudual's nickname was "le Bourgeois" (Middle-class man) which was the Francization of the origin Breton, "Bouric'h," but this could be wrong. This courageous Briton captain had in fact showed his bravery in various battles to the end of the One Hundred Years War, and particularly during the siege of several cities so he was called "le Bourgeois" (towns' defender).
As a reward for his gallant services, he was named Captain of Pierrefonds in 1436 and of Saint-Germain-en-Laye in 1438, Governor of Monfort-l'Amaury (this area was part of the Duke of Britain's domain.) On January 21,1450 he was named Bailiff of Troyes but e a few months later he was killed by cannon fire at the siege of Cherbourg.
