Brunulphe II, Duke or Prince of the Franks, was the successor of Hidulphe, the son of Hidulphe and Aia, VI, 63 Dagobert killed Brunulphe at Blaton p. 473, leaving 4 sons. Continued in Book VII: pref. p. xviii. pp. 421-427

Vol. II, pp. 475-476:

Aubert or Vaubert I, 6th prince of Hainaut, married Oda of Suabia, became father of Vaubert II and Ausbert.

Vaubert II was 7th prince of Hainaut, and was a senator, as was his brother Ausbert. He married Rothilde, daughter of Amalaric, King of Spain, with whom he had Vaubert III, who died before his father. He had married Bertilie, with whom he had Waldtrude, who inherited the principality.

Saint Vincent, husband of Waltrude, was the 8th prince of Hainaut, and was count of Hainault, calling himself Madelgaire or Mauger. He had a brother named Brunulphe who died before him, leaving a daughter named Saint Aia.

Hidulphe was the ninth prince of Hainaut, as husband of Saint Aia, niece of Waltrude. He became Duke of Lower Austrasia or Louvain through his marriage to Aia.

...De même Wausbert fut père d'une postérité à la fois sainte et illustre : car Wausbert engendra le duc Waubert et Brunulphe ; Waubert eut de Bertilie, Waldetrude et Aldegonde ; Waldetrude eut de Vincent, Landric, évêque de Metz, et Denthelin. Ceux - ci renonçant à leur duché et à tout leur temporel, le duché, par droit héréditaire, fut dévolu à Aia, qui avait épousé Hisdulphe.

La même légende, après plusieurs autres détails, poursuit ainsi : Brunulphe, neveu de sainte Aia par la sœur de celle-ci, et fils du comte de Templatum, succéda, en qualité de plus proche héritier, au duché ci - dessus nommé, et fut tué dans la suite à Blaton par le roi Dagobert. Brunulphe laissa orphelins trois fils et une fille unique; mais son duché fut en majeure partie saisi par Dagobert. Après la mort de Brunulphe son duché fut partagé, et le comté que l'on appelle de Mons échut à Albérie, le plus jeune de ses fils. ...
