A deed of 1078, purportedly made at Saint-Dié, records the return to St. Denis' Abbey by Gerhard's successor, Theodoric II, Duke of Lorraine, of the possessions usurped by his father, and is signed by several high dignitaries of the time both lay and ecclesiastical, including Pibon, bishop of Toul, Theodoric, bishop of Verdun, and Rembald, provost of Saint-Dié, as well as three counts and several other lords. This deed is however also considered a St. Denis forgery by many historians, including Richer of Senones, himself a monk of the Vosges.
