  Research Notes:

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".

He succeeded his father in 1181 as Seigneur de Montfort-l'Amaury. A charter dated Feb 1199 recalls a donation to the leprosery of Grand-Beaulieu near Chartres by "Amauricus de Monteforti", with the consent of "Amauricus parvus filius eiusdem Amaurici, qui erat sub custodia Amaurici de Mestenon", confirmed after his death by "Simon frater eius et successor", and a later donation by "Simon iste comes Ebroicensis et Mahaudis [presumably an error for Amicia] uxor eius".

The necrology of Haute-Bruyère lists members of the Montfort family who are buried in the abbey, including "…comte Simon…et de sa femme la contesse Amicie…". 1
