All members descended from Cunigunda of France, a granddaughter of the West Frankish king Louis the Stammerer.
He married Matilda, a daughter of the Saxon margrave Hermann Billung and widow of Count Baldwin III of Flanders.
With Godfrey's uncle Duke Theodoric, both Lower and Upper Lorraine then were held by the House of Ardennes.
He openly rebelled, campaigned the Lower Lorraine lands and was finally declared deposed by the emperor.
He reconciled with the emperor and in 1065 regained the Duchy of Lower Lorraine from the hands of King Henry IV.
Both duchies were in the control of the dynasty until 1046, when the rebellions of Godfrey ΙΙΙ the Bearded led to the loss of both titles.
The Castle of Bouillon is first mentioned in 988 in a letter to Godfrey Ι the Captive from his brother Adalberon, Archbishop of Reims.
