Gui Comte de Thouars Duc de Bretagne

  Information about this person:

• Background Information. ¹⁴¹
Guy de Thouars, brother of Almery, Vicomté de Thouars, married Constance de Bretagne who died 4 or 5 September 1201, at Nantes, and was buried at Villeneuve. In 1201, after her death, Guy de Thouars was administering the honor of Richmond. The King ratified leases granted by him, and in 1202 he had license to sell his wood of Richmond, half the proceeds to go to the King and half to himself. On 2 Apr 1203 the King ratified the yearly farm to be paid by him for the honor. Later in that year he joined Philip Augustus, and his English lands were confiscated, grants being made from them in September 1203. This terminated his connection with Richmond. In 1204, he invaded Normandy at the head of the Bretons. In Brittany, after Constance's death, he occupied the position of regent until 1213, when Piers de Braine married his daughter Alice and was made Duke. He then disappears from history, and the date of his death is not certainly known. He was ultimately buried at Villeneuve at the same time as his wife and daughter.
