  Research Notes:

Robert of Torigny records that "frater eius Symon" succeeded in 1140 on the death of "comes Ebroicensis Amalricus".

He succeeded his brother as Comte d'Evreux, Seigneur de Montfort-l'Amaury. During the 1159 war between Henry II King of England and Louis VII King of France, Simon handed his castles of Rochefort, Montfort and Epernon to King Henry, which forced King Louis to make a truce as his communications between Paris, Orléans and Etampes were thereby cut.

Robert of Torigny records the death in 1182 of "Simon comes Ebroicensis" and the succession "in comitatu Ebroicensis in Normannia" of "Amalricus filius eius" and "in comitatu de Rocha et in terra Francie" of "Simon alter filius eius". The necrology of Haute-Bruyère lists members of the Montfort family who are buried in the abbey, starting with "conte Amaury…qui premier fonda l'eglise, dou fil le conte Simon le Chauf qui gist a Evreux". The necrology of the church of Evreux records the death "13 Mar" of "Symon comes Ebroicensis qui dedit c solidos" and the donation of "xl solidos" by "Amaricus filius eiusdem comitis". ¹
