Godfrey was count of the Jülichgau from at least 924 to 936 and probably even until 949. He he was the younger brother of Wigfried, who was archbishop of Cologne from 924 to 953 and arch-chancellor of his cousin King Otto I from 941.

For a time, Godfrey was known as Count Palatine of Lotharingia. The office was filled from 911 to 915 by Reginar and subsequently by Wigeric. Since Wigeric died before 922, and king Charles was deposed 923, there is a short window of time in which Godfrey could have been used as deputy to his father-in-law in Lorraine.

But since Godfrey was also the nephew of Henry I, the cousin of Otto I, and the brother of Otto's close adviser and later chancellor Wigfried, it is also possible that this office was entrusted to him after 923 despite his connection to the deposed Charles. The fact that his son Godfrey was himself Duke of Lower Lorraine in 959, and initially was as deputy to Archbishop Bruno of Cologne, Otto's brother and Wigfried's successor in both offices, suggests that his connections with Saxony were more important than those with West Francia.
