Of his maternal grandfather, Estienne Bellanger, "Financial Controller of the Parisian general revenue" ("« contrôleur des finances en la recette générale de Paris »"), and of his background, we know almost nothing. We know more about his wife, Catherine Millet, whose father, Guillaume II Millet, Lord of Caves, was secretary of the King's finances, and whose grandfather, Guillaume I Millet (149?-1563), qualified in medicine in 1518, was doctor to three kings in succession (Francis I, Henry II and Francis II). He married Catherine Valeton, daughter of a property tax collector from Nantes, Audebert Valeton, who, accused of involvement in the Affair of the Placards, was "burned alive on wood taken from his house" on 21 January 1535 at the crossroads of "la Croix du Trahoir" (the intersection of the Rue de l'Arbre-Sec and the Rue Saint-Honoré), in front of the "Pavillon des singes", where Molière lived almost a century later.
