The southern branch of the Oldenburg house, founded by Henry I (died 1167), who made Wildeshausen on the Hunte his seat and built its castle.
Henry II ruled until 1198; his sons Henry (III), later styled of Bruchhausen, and Burchard now hold Wildeshausen with the advocacy of the old Alexander collegiate church, and the Bruchhausen lands to the east toward the Weser. A separate Bruchhausen line comes later; on 1 January 1200 Bruchhausen is part of the brothers' inheritance.

Where the sources disagree
- Henry II's death year (1198) comes from de.wikipedia ('ruled until 1198'); FMG's entries for this generation were not reached. Whether he died on crusade is not pinned.
Evidence: Only de.wikipedia's short account; no dated charter checked for 1199-1200.
On the map: Rough blocks; the line's lands were scattered.
