Henry III authorized him to succeed his father as Duke of Upper Lorraine in 1044, but refused him the ducal title in Lower Lorraine, for he feared the power of a united duchy. Instead, Henry threatened to appoint his younger brother, Gothelo, as Duke in Lower Lorraine. At a much later date, Godfrey became Duke of Lower Lorraine, but he had lost the upper duchy by that point in time.
