Orderic Vitalis records that "Hugo filius Herberti" and his wife “Bertam ipsius relictam, Tedbaldi Blesensium comitis sororem” had “filium...Herbertum et tres filias”, of whom the third married “Johanni domino castri...Flecchia” (which would be difficult to sustain chronologically and confuses the children of Hugues [IV] Comte du Maine with his sisters) and had three children “Goisbertum, Heliam et Enoch”. Orderic Vitalis names "Helias, Johannis et Paulæ filius, Hugonis Cenomannorum consulis consobrinus". A charter dated 13 Feb 1087 records donations to Angers Saint-Aubin by "Johannes de Fissa", with the consent of "Helias filius eius". Orderic Vitalis records that, after Ugo d´Este arrived in Maine, and was helped by “Gaufridus Madeniensis et Helias aliique cives et oppidoni” to secure his inheritance, dated to 1090, adding that “Helias de Flechia” captured “Hoellus antistes” who opposed them and held him in chains until the newly arrived count was received “in urbe Cenomannica”. Orderic Vitalis records that “Helias consobrinus eius”, noting his legitimate claim to Maine because “filia Herberti comitis” had married “Lancelinum de Balgenceio” by whom she had “Lancelinum Radulfi patrem et Johannem meum genitorem” [an inaccurate description of the descent], suggested to Hugues that he returned “in patriam tuam” and sold him the county, which he did for “x milia solidorum”, dated to .
He succeeded as Comte du Maine. Orderic Vitalis records that “Helias [de Balgenceio]” was “heres...soceri sui Gervasii de Castro Ligeri” whose daughter he had married. "Comes Helyas qui totius patrie dominus est" donated property “quia de patrimonio uxoris sue Mahildis fuit, etenim Elisabeth, matris Gervasii, patris Mahildis, conjugis sue” to Château-du-Loir by charter dated to . A charter dated to  records confirmation of donations to Angers Saint-Aubin by "Elias…filius eius…et frater eius Gaufridus" after the burial of their father. "Gener suus...Cenomanice civitatis Helyas" confirmed a donation made to Saint-Guingalois “in castro...Ledi fondato” by “supradicti castri dominum Gervasium” to Château-du-Loir on the death of “uxor sua Eremburgis” by charter dated to , subscribed by “...Garsendis uxor eiusdem Gervasii...”. He delayed his departure on the First Crusade in 1097 because William II King of England threatened to capture Maine in his absence, and attacked Robert de Bellême in 1098, but was captured and handed to King William at Rouen. The town of Le Mans was captured by Robert, son of Hugues de Montfort, and handed to Guillaume Comte d'Evreux and Gilbert de Laigle. Helias was released, and returned to la Flèche and the castles he owned de iure uxoris. Helias recaptured the city in late 1100 after the death of King William II. "Helias comes Cenomanensis" donated property to the monastery of Saint-Pierre de Couture, for the soul of "monachatu Enoch fratris mei", by undated charter dated to . The Annals of Waverley record that “Philippus de Brausa et Willelmus Malet et Willelmus Barnard et Helias comes Cenomanniæ” were deprived of their lands in 1110.
The necrology of Le Mans Cathedral records the death "V Id Jul" of "Cenomannorum comes Helias". The Chronicæ Sancti Albini records the death "1110 V Id Jul" of "Helias comes". The Annales Sancti Albini Andegavensis record the death "V Id Jul" in 1110 of "Helias comes". 2
