van de Pas: "In 1087 Godefroid married Sibil de Porcean, daughter of Roger, comte de Château-Porcean, and his wife Ermengarde. In that year he became count of Château-Porcean, succeeding his father-in-law. He and Sibil had two daughters, Elisabeth and Flandrine, who would both have progeny.

In 1102 Godefroid became count of Namur and divorced his wife. She was married twice more, to Enguerrand I de Coucy, seigneur de Boves de Coucy, and Guitier, comte de Réthel, but did not have further progeny.

In 1109 Godefroid married Ermesinde, comtesse de Luxembourg, widow of Gottfried, Graf von Dagsburg, and daughter of Konrad I, Graf von Luxemburg, and Clémence de Poitou, heiress of Gleiberg. They had five children of whom Henri, Clémence, Adele and Beatrice would have progeny.

Godefroid remained a faithful supporter of the emperor in Lower Lorraine. In 1119 he supported his brother Frederic, bishop of Liège against Alexander von Jülich who was seeking to take over from Frederic as bishop. Godfried I 'with the Beard', duke of Lower-Lorraine, comte de Louvain, a supporter of Alexander, was defeated at Huy, but his forces ravaged the county of Namur and the bishopric of Liège in retreating.

In 1121 Godefroid founded the abbey of Floreffe, but he quarrelled with the religious authorities, pillaging the lands in Tourinne of the abbey of Stavelot in the Hesbaye. He also destroyed the abbey of Gembloux, following a dispute over the election of the abbot in 1136, and he massacred the monks. Three years later he renounced the county in favour of his son Henri and retired to the abbey of Floreffe. He died a few months later on 19 August 1139."
