Evidence suggests that one of Dunstan's biographers was a monk who studied under Bishop Everarcher of Liege, friend and protege of Bruno of Cologne.

, brother of Otto I; Bruno fostered Otto's policy of maintaining a balance of power between the Carolingian rulers and their rivals, and he also persuaded Lothair to give Burgundy to Hugh the Great's son, Otto, instead of annexing it; forced to attend a council of Emperor Otto I at Cologne (June 965); married Otto's daughter Emma later that year; his freedom of action increased greatly after Bruno's death (December?
