Guillaume of Jumièges records that "comes Gislebertus filius Godefridus comitis" inherited his father´s county before he was killed. Named as son of "Godfrey" by Orderic Vitalis.
Comte d'Eu. "Gislebertus filius Godefridi comitis…" witnessed the charter dated to [1030] under which Robert II Duke of Normandy confirmed rights of Mont Saint-Michel. Orderic Vitalis records that "tempore Rodberti ducis Gislebertus comes Brionniæ" invaded "in pagum Vimmacensem" [Vimeu] but was repulsed by "Ingelrannus Pontivi comes", adding that "miles...Herluinus" fled the battle and afterwards founded "in patrimonio suo in loco...Beccus...cœnobium sanctæ Dei genitricis Mariæ". Le Prévost dates this event to "antérieure à 1034, époque présumée de la fondation du Bec". He was appointed guardian of Guillaume II Duke of Normandy after the death in 1040 of Alain III Duke of Brittany.

He was murdered by his cousin Raoul de Waco, after which Brionne was kept by Guillaume II Duke of Normandy. On the other hand, another passage in Orderic Vitalis records that "Rodbertus de Witot" had been exiled "propter occisionem Gisleberti comitis". Robert of Torigny names "Radulfo de Waceio filio Roberti archiepiscopi Rothomagensis" as murderer of "Gislebertus filius…Godefridi". Guillaume of Jumièges records that "Gislebertus comes Ocensis filius Godefridi comitis...tutor Willelmi pueri sed domini...cum Fulcoio filio Geroii" were killed while riding with "Wascelino de Ponte Erchenfredi", adding that the crime was committed by "Odonis Grossi et audacis Roberti filii Geroii" at the instigation of "Rodulfus de Waceio filii Roberti archiepiscopi". The necrology of Saint-Nicaise de Meulan records the death of "Gislebertus comes Briognensis", undated but listed among other deaths recorded in Mar.

The name of Gilbert's wife is not known. 2
