Bouchard founded the priory of Saint-Sauveur-lès-Bray just north of the castle on the opposite bank of the Seine.
His offspring were Bouchard II, le Barbu (the Bearded); Thibault de Bray, of Montlhéry, and Albéric, Lord of Vihiers.
[3] Boso probably taking advantage of the invasion of the kingdom by Bruno of Cologne in 960, burned down the town of Bray and recaptured the castle.
[4] The first Bouchard died shortly after because his widow Hildegarde[5] eventually asked for the support of Count Renard I of Sens.
Odo I of Blois recovered most of the property and rights of Saint-Sauveur and united this priory to the Chartres abbey of Bonneval.
