Everstein

The Eversteins rose on the Upper Weser as Barbarossa's kinsmen and partisans against Henry the Lion, and after 1180 took fiefs from Cologne.

Albert III, a Staufen cousin through his mother and married into the Wittelsbachs, holds the castle of Everstein on the hills east of Holzminden, the Weser crossings at Polle (a castle built about 1200) and Ohsen, and rights reaching south to the Diemel. They are the Staufen family of the Weser hills, the Welfs' natural enemies; their side in 1199-1200 is not directly attested.
