A comital house on the Leine below Hildesheim, holding the castle of Poppenburg by the river crossing at Burgstemmen and acting under the bishop of Hildesheim.
Count Bernhard appears in a charter of Bishop Hartbert dated between 1199 and 1206, giving up his family's administration of the saltworks near Hemmendorf; whether that act falls before 1 January 1200 is not pinned.
