Research Notes:

"Rodolphus Cameracensis comes" is named as third of the three sons of Baudouin and his wife Judith in the list of counts of Flanders recorded in the Cartulaire de Saint-Bertin. The Annales Blandinienses records "Rodulfus comes et abba factus est" in 882.

The date when he was installed as Comte de Cambrai is not known. However, his brother Baudouin II Count of Flanders supported the election of Eudes as king of France in 888, and it is suggested that Raoul's appointment must have taken place around that time. Baudouin quarrelled with King Eudes over the succession to the lay abbacy of Saint-Bertin in 892, so it is unlikely that the king would have favoured members of the count's family with a comital appointment after this episode. Raoul supported his brother's attack on the county of Vermandois and captured Arras, Saint-Quentin and Péronne after 5 Jan 892, but was captured by Héribert I Comte de Vermandois and killed. The Annales Vedastini name "Balduinus…comes et Rodulfus frater eius necnon et Ragnerus" when recording that they joined Zwentibold Duke of Lotharingia in 895. The History of Waulsort monastery records that "Cameracensis comes Rodulfus…regalis consanguinitatis" invaded the territory of "quatuor Heriberti filios" with the consent of "rege Francorum…avunculo suo" but was expelled, but this source confuses Raoul, son of Baudouin I, with Comte Raoul [II] de Gouy...

The Annales Vedastini record that "Rodulfus comes" disrupted the peace in 896 and took the property of "Heribertus et Erkingerus", that "Odo rex" besieged "castrum sancti Quintini et Peronam" and expelled Raoul's supporters, and that Héribert killed Raoul. The Annales Blandinienses record that "Rodulfus comes" was killed "IV Kal Iul 896". ³
