Appears that he and his brother, Jean, did not appear to have inherited property. It is likely that they had an elder brother, Louis du Bois, who was Seigneur de Beaufremez at Linselles near Lille. Under the system of primogeniture, it was the custom for the eldest son to inherit all the property and titles of his father. It is probable that the American Du Bois immigrant, Louis, was named after this uncle. Pierre lived near Herseau, Belgium.
