Thibaud de Montlhery

     Thibaud de Montlhery was born circa 970 at Montlhery, Essone, Île-de-France, France. He was the son of Bouchard de Montmorency and Elizabeth de Crecy. Thibaud de Montlhery died in 1031 at Montlehery, Essone, Île-de-France, France.
     Thibaud ruled from 970 to 1031 and was succeeded by his son Guy I, who ruled until 1095. Guy I's children married into other local noble families: his daughter Melisende married Hugh, count of Rethel, and another daughter Elizabeth married Joscelin of Courtenay. Through these marriages and subsequent Montlhéry participation on the First Crusade, Guy I was the ancestor of the ruling dynasties of the crusader Kingdom of Jerusalem and the County of Edessa. Another daughter, Alice, married into the Le Puiset family, and a son, Guy, became count of Rochefort. Guy I was succeeded by Milo I, followed by Milo's sons Guy II and Milo II. In 1118, after many disputes with the rebellious lords, Louis VI of France ordered the castle to be dismantled and turned the town into a royal residence. Louis VI had himself been married to a granddaughter of Guy I, Lucienne of Rochefort, from 1104 to 1107.¹
