Hugh I of Le Puiset
Hugh I of Le Puiset (died 23 December 1096), son of Everard I of Breteuil and his wife Humberge. In 1067, taking advantage of the weakness of Philip I of France, he seized the royal castle of Puiset and settled there. In 1073, Theobald III, Count of Blois, became Count of Chartres and did not hesitate to defy royal order, defeating the royal army in 1079 at Le Puiset. He took as prisoner Ivo, Bishop of Chartres, and kept him confined for two years. Hugh married Alice of Montlhéry, daughter of Guy I, lord of  Montlhéry, and Hodierna de Gometz. The family of Montlhéry was also part of the turbulent nobility that King Louis VI would have to put down a generation later. The alliances of the Montlhéry Clan formed a broad network of nobles who engaged heavily in the Crusades. Hugh and Alice had at least nine children: Hugh established a priory of Marmountier at Le Puiset. See also the Houses of Montlhéry and Le Puiset.
