Maisnisias, which genitor meus Gauzlinus et mater mea Adeltrudis habuerunt, to the abbey of Saint-Maur-sur-Loire, confirmed by Dodon Bishop of Anjou by charter dated 1 Mar 839 [Rorgo] [I] (-16 Jun [839/40], bur Abbaye de Saint-Maur de Glanfeuil, Anjou). Considering that Guy was named as comte du Maine in [832/34], one possibility is that this enthronement was incorrectly dated in this source.
The Annales Bertiniani record that in 878 "filii Gozfridi" attacked "castellum et honores filii Odonis" which King Louis le Bgue granted to "isdem Gozfridus...[et] filios suos" who abandoned partem Brittonibus and swore allegiance to the king].
The origin of the wife of Comte Bernard is deduced from the Historia Inventionis Sanctii Baudelli which names "Gothorum princeps Bernardus cum avunculo suo Gauzleno tunc inclito Abbate, futuro autem episcopo", the latter being reported in other sources as the son of Comte Rorico [I] (see below).
Einhard names "Karlomannumet Pippinum atque Grifonem" as the three sons of "Karlus maior domus" when recording the latter's death, specifying that "Grifominor natumatrem habuit Swannhilde neptem Odilonis ducis Baioariorum".
His father bequeathed to Grifo the central part of his territory, but his stepbrothers Carloman and Ppin deprived him of this inheritance and divided the land between themselves.
If that is correct, it is unlikely that in the case of Maine each short-lived period of ducal status was linked to a military governorship normally associated during the earlier Merovingian Frankish period with march frontier areas (see the document FRANKS, MEROVINGIAN NOBILITY).
It is suggested therefore that these two dukes ruled the county of Maine in the same way as earlier and later counts.The dating appears early for him to have been identified with Ragenold Comte de Roucy but he could have been the same person as BERENGER, son of --- (-13 Dec [892 or after]). A notice of Saint-Martin de Tours records that officials of the church went to Le Mans 13 Jun 892 demanding justice from "Beringerium comitem" (-after 13 Nov 912). Domni Gauslini comitis, domni Ervei comitis, domni Gausberti comitis, domni Fulconis signed the charter dated 13 Nov 912 under which domnus Robertus Sancti Martini...comes confirmed the independence of Marmoutier abbey (-after 13 Nov 912). Domni Gauslini comitis, domni Ervei comitis, domni Gausberti comitis, domni Fulconis signed the charter dated 13 Nov 912 under which domnus Robertus Sancti Martini...comes confirmed the independence of Marmoutier abbey Her parentage and marriage are confirmed by Abbo who names "Rotgaire, comte et neveu de Hugues" as one of the supporters of "Huguesprince et gouverneur de Bourges", on the assumption that this passage means that the sister of Hugues was the mother of Rotger, dated to 889 from the context([855/65]-before I Nov 900).His birth date range is estimated from the estimated date of his marriage which, assuming that his wife's origin is correctly shown below, must be reasonably accurate.Einhard records that his mother incited Grifo to rebel against his half-brothers, during the course of which Carloman imprisoned Grifo "in Novo-castello...juxta Arduennam", adding that it was said that Grifo remained imprisoned there until Carloman left for Rome (dated to late 747, see below).He invaded Bavaria where he was recognised as duke in 748 in succession to Duke Odilo, but was deposed by Ppin who installed their nephew Tassilo III as duke. ] du Mans [748/49]: according to the Royal Frankish Annals, in 748 Ppin granted Grifo the duchy of Mans and twelve counties in Neustria, although the source does not identify these counties more precisely.It is unclear from the wording whether this Karivius was the same person as Charivius who was named on 5 Mar 723. Gauziolenum" to Rouen to be invested with the bishopric.
