Research Notes:

The Chronicon Mauriniacensi records that "Stephanus Cancellarius" arranged the marriage of "nepti sua" and "Amalrico de Monteforti", adding that her dowry was "honore de Rupe-forti" [Rochefort].

Du Chesne suggests that the widow of Amaury [III] de Montfort Comte d’Evreux married, as her second husband and his first wife, Robert de France Seigneur de Dreux. He bases this on a charter dated to [1 Nov 1183/31 Mar 1184] in which Philippe II King of France confirmed the property of Notre-Dame de Colombs, including property "in loco Campus à la Drouë" donated by "Robertus comes de Drocis et de Montfort" and "domum de là Nouë" donated by "Simon de Drocis in sua ultima voluntate". Du Chesne’s argument is that Robert Seigneur de Dreux could only have been entitled to "le titre de comte de Montfort, don’t le roy le rehausse" from "un mariage fait avec la douairiere de la mesme comté". He also suggests that "Simon de Drocis", also named in the same charter, was the son of this marriage. There are three difficulties with Du Chesne’s argument. Firstly, Amaury [III] de Montfort was comte d’Evreux not "comte de Montfort", a title which does not appear ever to have been borne by members of his family. Secondly, the chronology is unfavourable for the widow of Amaury [III], who was probably born in [1110/15] at the latest, to have married Robert de Dreux whose birth is estimated to [1124/26]. Thirdly, it is unlikely that Agnes would have given the name Simon to a son born from this supposed second marriage, given that she already had a son of that name by her marriage to Amaury. In conclusion, the evidence of the [1183/84] charter alone is insufficient to corroborate this marriage. ¹
