Eustachie de France

7. [EUSTACHIE de France ([1095/1100]-[1143]). She and her husband are named by Kerrebrouck who cites no primary source on which the information is based[359]. Presumably this is based on Sainte-Marthe who states that “Eustache comtesse d’Estampes et de Corbeil, femme de Jean d’Estampes” is named “sœur du Roy Louys le Gros” by “Jacques du Breuil religieux de sainct Germain des Prez les Paris”, adding that the latter records that she founded the abbey of “Hierre” [Kerrebrouck says “Yerres”[360]] where she was buried[361]. Sainte-Marthe also says that “c’est d’elle que semble parler Nangis disant que le Roy Philippe I eut de Bertrade de Montfort deux fils et une fille qu’il nomme Comtesse d’Etampes”. “Nangis” has not been identified: the Chronicle of Guillaume de Nangis starts in 1113 during the reign of Louis VI King of France. Eustachie is not named by Père Anselme among the children of King Philippe I[362]. Could there be confusion with Eustachie, daughter of Ferry, whose second husband was Jean d’Etampes (see the document PARIS REGION NOBILITY - CORBEIL & ROCHEFORT)?.

Un'altra presunta figlia di Filippo e Bertrada, Eustachia, è spesso menzionata, ma la sua esistenza non è certa.
