"...Nivelonis..." subscribed the charter dated 987 under which Eudes I Comte de Blois reaffirmed the privileges of Chartres Saint-Père. The chronology suggests that this subscription must refer to an earlier Nivelon. "...Nivelonis..." subscribed the charter dated 1024 under which Eudes II Comte de Blois reached agreement with Chartres Saint-Père about “terram in comitatu Dunensi...Boscus Medius”.
Seigneur de Chaumont: the Gesta Ambaziensium Dominorum records that the father of Eudes II Comte de Blois had constructed a castle on the hill of Chaumont near the place previously called Vacherie-de-la-Comtesse ("prope locum antiquitis Vaccaria Comitissæ...in colle Calvimontem") and that Eudes had installed “Nevolum...militem suum” there in order to oppose Lisoie Seigneur d’Amboise. “...Nevelonis...” subscribed the charter dated to [1032/37] under which "domna Agnete domni Wanilonis tesaurarii uxore" donated revenue from “in terra nostra vineis Dagfridi clerici” to Marmoutier, with the consent of “suo seniore Guanilone”. "...Nivelo de Carnoto..." subscribed the charter dated 1033 under which Geoffroy II “Martel” Comte d’Anjou bought “molendinum...prope ecclesiam Sancti-Martini” from “Erfredo Ruffo...milite Burchardis senioris de Charismot”. It is not known whether this charter refers to the same Nivelon. However, the charter dated 3 Jun 1040, which records the donation by "Hugo Dublellus archidiaconus et Odo Dublellus frater eius" of "ecclesiam Sancti-Beati" to La Trinité de Vendôme, names Nivelon [I]’s son "Nivelongis Pagani, filii Nivelonis de Carnoto".
Seigneur de Fréteval: "...Nivelonis de Fracta-Valle..." subscribed the charter dated 31 May 1040 under which Geoffroy II “Martel” Comte d’Anjou confirmed the foundation of Vendôme La-Trinité and donated property. "Nobilem…Nivelonem" donated property by charter dated to [1041/48] which names "suus filius Fulcherius…fratres Girardus et Nivelo quem cognominant Paganum". A charter dated to [1042/44] records the castle of Fréteval was captured by Geoffroy II "Martel" Comte d'Anjou, but later recaptured by Nivelon’s son. “...Niuelo...” subscribed the charter dated to [1039/60] under which Thibaut III Comte de Blois confirmed the donation to Marmoutier made by “Salomon...apud castrum Lauarzinense”. "Nobilem…Nivelonem" donated property to Marmoutier by charter dated to [1041/48] which names "suus filius Fulcherius…fratres Girardus et Nivelo quem cognominant Paganum".
Married Ermentrude, daughter of ---. A charter dated to [1042/44] records that "matrona quondam Ermentrudis…uxor Nivelonis" donated “ecclesia...in honore sancti Leobini constructa...ex patrimonio suo” to Chartres Saint-Père, the failure of her husband to confirm the donation after her death, his instruction on his deathbed to "filius eius Paganus" to confirm it, the death in battle of Pagan while retaking the castle of Fréteval from Geoffroy "Martel" Comte d'Anjou, and the confirmation of the donation by "frater eius Fulcherius". Indications of Ermentrude’s ancestry are provided by earlier charters of Chartres Saint-Père: a charter dated Feb 981 records that "Fulcherius" had been granted “abbatiam Sancti Leobini...in suburbio Carnotensis” [the same which was later donated by Ermentrude, see above] by Eudes I Comte de Blois, and had granted it to “Sigismundo presbitero”, witnessed by “Odo comes, Fulcherius abbas, Vivianus...”, while a charter dated 988 records that "Vivianus...consensu fratris mei Fulcherii" had donated other property to Chartres Saint-Père for “patris mei Fulcherii seu matris meæ Anstrudis vel fratris mei Rodulfi jam defunctorum”. As Nivelon [I] and Ermentrude gave the name Foucher to their second son, it is probable that she was a descendant of this family.
The necrology of Chartres Cathedral records the death “VII Kal Feb” of “Ermentrudis uxor Nivelonis” adding that “alodum in suburbio Beati Andree” was donated for her soul. 2
