NIVELON [III] de Fréteval, son of FOUCHER Seigneur de Fréteval & his wife Hildeburge Goët (-7 Jan [1129 or after]). "Filii eius Nevelo et Hamelinus…" consented to the donation by "Fulcherius Nevelonis filius" by charter dated to [1072/84][1547]. A charter dated 29 Jun 1087 records the settlement of a dispute between La Trinité de Vendôme and "Nivelo Fracte Vallis, filius Fulcherii, majoris Nivelonis filii" concerning "terras de Buissello", with the consent of "fratre eius Hamelino, Comitissa uxore eius Eustachia, item alia comitissa sorore eius, atque altera sorore eius…Hildeburgis, tertia Pagana et filia Guanilonis…Agnes"[1548]. Seigneur de Fréteval. "Miles...Niuelon" granted privileges to the monks of Saint-Martin, with the consent of "filii sui Ursionis et Comitisse...sororis sue", by undated charter[1549]. "Niuellus filius Fulcherri" withdrew claims "in terra de Stuno et in molendinis de Fonte Merlandi" in favour of Marmoutier, with the consent of "uxore sua Comitissa...et filio suo Ursione...et Haimelino fratre suo", by charter dated to [1069/80][1550]. "Nivelo filius Fulcherius dominus castri…Fractavallis" donated property with the consent of "Hamelinus de Montiniaco frater domini Nivelonis" by charter dated 1096 which names "comes Stephanus et Adela uxor eius"[1551]. "Nivelo generis nobilitate" donated "terram sancti Petri...Amprainvillam" to Chartres Saint-Père by charter dated to [1097] which also lists minor donations made by "sorori mee Hugonis Dunensis vicecomitis uxori nomine Comitisse pro assensu...Hamelino fratri meo...annuente filio meo Urseo", witnessed by "...Comitisse, Pagane, sororis eius, Hugonis vicecomitis..."[1552]. The necrology of the abbey of Châteaudun Saint-Avit records the death "VII Id Jan" of "Nivelo filius Fulcherii"[1553].
mCOMTESSE, daughter of ---. "Niuellus filius Fulcherri" withdrew claims "in terra de Stuno et in molendinis de Fonte Merlandi" in favour of Marmoutier, with the consent of "uxore sua Comitissa...et filio suo Ursione...et Haimelino fratre suo", by charter dated to [1069/80][1554]. According to Salies, the wife of Nivelon [III] was named "Milesende", citing a charter of Marmoutier dated 1096[1555]. However, this suggestion appears based on a misreading of the charter in question. The document records the donation of land "a castro...Fracta Vallis usque ad Vernolletum" to Marmoutier by "Rotbertus Michael et Almarus frater eius", with the consent of ("concesserunt") "Rainaldus Rufus, de cujus feodo memoratæ res erant...et uxor eius nomine Milesendis", specifies that "ipse" (signifying "Rainaldus Rufus") had "a nobis [i.e. from the monks] quadraginta solidoset uxor eius decem". The words omitted in this quote between "erant...et" are "et fevum ipsum eo tempore de Nivelone filio Fulcherii, tunc domino Fractæ Vallis, tenebat". Salies has therefore incorrectly linked "et uxor eius nomine Milesendis" to "de Nivelone filio Fulcherii", despite the different cases of the two names and despite use of the plural form "concesserunt" which indicates consent by more than one person, who from the context could only be "Rainaldus Rufus...et uxor eius nomine Milesendis".
Nivelon [III] & his wife had one child:
