Gozelon succeeded his brother Godefroid I as Duke of Lower-Lorraine in 1023, and in 1033 he was made Duke of Upper-Lorraine as well, which made him one of the most important rulers within the German Empire and a powerful ally of King Conrad II of Germany. After Gozelon's death, King Conrad's successor Heinrich III decided to curb Lorraine's power and split it up again. He divided it between Gozelon's sons Godefroid II and Gozelon II.

Stirnet show Gozelo as brother of Godefroid I, Count of Verdun, Duke of Lower-Lorraine (d 26 Sept 1023).
Godefroid, who succeeded his nephew Otto (the son of his sister Bonne and her husband Charles "the Fat") as Duke of Lower-Lorraine in 1005 (or 1012) was a loyal supporter of Emperor Heinrich II of Germany, and he fought against unruly vassals like our ancestors Lambert I "The Bearded", Count of Leuven, who was killed in the battle of Florennes in 1015, and Dirk III, Count of Holland, who won the battle of Vlaardingen on 29-7-1018 and even managed to capture Duke Godefroid and his ally Bishop Adalbold II of Utrecht. Duke Godefroid and the Bishop were released unharmed not long afterwards, having been taught a lesson, but certainly not feeling any friendlier towards the Count of Holland.
