Guy II the Red of Rochefort

Guy II the Red de Montlhéry (died 1108), son of Guy I, Seigneur de Montlhéry, and Hodierne de Gometz-la-Ferté. He held the titles of Count of Rochefort-en-Yvelines and Châtelain of Châteaufort and of Gometz, and was Seneschal of France under Philip I the Amorous, 1104-1106.

Guy joined with the Lombard contingent in the minor Crusade of 1101, later joining the army of Stephen of Blois. He apparently rebelled against Louis VI, King of France (once his son-in-law), when he was killed.
