Returning home in 1380 after a successful campaign, Carrouges married Marguerite de Thibouville, only daughter of the highly controversial Robert de Thibouville. Thibouville was a Norman lord who had twice sided against the French king in territorial conflicts, betrayals he was lucky to survive, albeit in reduced circumstances. By the union of Marguerite and Carrouges, Thibouville hoped to restore his family's status and wealth while Carrouges was hoping for an heir from the young Marguerite, whom contemporaries described as "young, beautiful, good, sensible and modest".
