The lordship of Bouillon was in the 10th and 11th century one of the core holdings of the
Ardennes–Bouillon dynasty, and appears to have been their original patrimonial possession.[1]
It is difficult to draw an exact list of the lords of Bouillon, as the lordship did not automatically follow the better documented ducal and comital titles held by the dynasty.
Since Bouillon is believed to be the patrimonial possession of the dynasty, one would believe the lordship was inherited by the oldest son.[2] Based on this assumption, one can set up a tentative list of the Lords of Bouillon:
^In the case of Godfrey the Crusader, he was the second son of Godfrey the Hunchback's sister. He inherited from his childless uncle, while the older brother Eustace inherited from their father.
