     "GOSSUIN [II] de Mons (-[1125/26]). Gérard Bishop of Cambrai confirmed the foundation of Aymeries priory by "Ermengardis de Mons...cum filiis suis...et filia" by charter dated 1088, subscribed by “...Gosuini de Montibus et Isembardi filiorum Ermengardis”[1565]. "Gossewinus de Monte Castriloco" confirmed donations made by “mater mea...Ermengardis” to Aymeries priory, with the consent of “fratris mei Isembaldi”, by charter dated to [1100][1566]. "Gossuini de Montibus, Gossuini de Avesnis, Widonis de Cervia, Hugonis de Lens" subscribed the charter dated 1117 under which Baudouin III Comte de Hainaut donated property to the monastery of Saint-Denis[1567]. “Gotsuinus de Montibus” donated property to “quemdam bone memorie virum Aybertum nomine Reclusum”, with the consent of “conjuge mea Ida et filiis nostris Ysaac...”, by charter dated 1122[1568]. The wording of the 1125 charter of his wife, quoted below, suggests that Gossuin was alive at that date, but his absence from the 1126 charter suggests that he was deceased at the time.
     "m IDA, daughter of --- (-[1126/35]). “Gotsuinus de Montibus” donated property to “quemdam bone memorie virum Aybertum nomine Reclusum”, with the consent of “conjuge mea Ida et filiis nostris Ysaac...”, by charter dated 1122[1569]. A charter dated 1125 records donations to Liessies, including the donation of land “inter Bovenies et Aath” made by “Rainerus de Mafles” in the presence of “Ida, uxor Gosuini Montensis et Ida uxor Widonis de Cirvia...in earum dominatu eandem terram tenebamus”[1570]. Reiffenberg records that “Ide” returned serfs to Ghislenghien, in the presence of “ses fils Gossuin et Isaac et d’Isembert leur oncle”, by charter dated 1126[1571]. “Isaac” donated serfs to Ghislenghien, for the souls of “mon père Gossuin de Mons et...de ma mère Ide”, with the consent of “mes frères Nicolas et Gossuin et ma sœur Ermengarde avec son mari Gautier”, by charter dated 1135[1572]. She is named in the charter dated 1143 under which Nicolas de Mons Bishop of Cambrai confirmed the property of Ghislenghien abbey founded by “genetricis nostræ Idæ”, including the donation of “tertiam partem...in Gisbecca” donated by “Gascuinus frater noster de Mons” for the soul of “matris nostræ Idæ” and “aliam partem in eadem villa Gisbecca” donated by “Domina Æva quæ cognominatur Domoisuns" for the soul of "viri sui Ægidii"[1573]."

     "The existence of two different noblewomen named Ida, one married to Gossuin [II] de Mons, the other to Guy de Chièvres, is confirmed by the 1125 charter quoted below. Roland, in his study of the seigneurs de Florennes/Rumigny, had suggested that they were the same person[557]. The suggestion proved controversial, the debate revolving around two charters dated 1143 and 1161 which name the founder of the abbey of Ghislenghien: Nicolas de Mons Bishop of Cambrai confirmed the property of Ghislenghien founded by “genetricis nostræ Idæ”, including the donation of “tertiam partem...in Gisbecca” donated by “Gascuinus frater noster de Mons” for the soul of “matris nostræ Idæ” and “aliam partem in eadem villa Gisbecca” donated by “Domina Æva quæ cognominatur Domoisuns" for the soul of "viri sui Ægidii", by charter dated 1143[558], and “Domina Eva de Cirvia que dicitur Domisons” [the same person named in the 1143 charter] donated “medietatem ville...Erbisul” to Ghislenghien by charter dated 1161[559]. The 1143 document also clarifies that Gossuin [III] de Mons and Eva de Chièvres jointly owned “villa Gisbecca” which, if Roland’s hypothesis is correct, would have been inherited from their mother. A rather garbled variation of the hypothesis had been indicated in the early 17th century by Gazet who said that Nicolas Bishop of Cambrai was “issu de la noble famille de Widon seigneur de Chieures et de madame Ide”[560]. The chronology would be tight for Nicolas to have been born from his mother’s supposed second marriage. The question is settled by the 1125 charter.
     "The parentage of the two persons named Ida is also controversial. The Marquis de Trazegnies suggests that they were half-sisters, daughters of Ada de Ramerupt, the wife of Gossuin de Mons being her daughter by her first husband while Guy de Chièvres’s wife was her daughter by Gauthier d’Ath[561]. This suggestion appears possible chronologically, although if correct the absence of the other daughters of Gauthier d’Ath/Ada de Ramerupt (see above) and of the son(s) of Geoffroy de Guise/Ada de Ramerupt (see the document NORTHERN FRANCE-VALOIS/VEXIN/VERMANDOIS) as joint suzerains of the 1125 property is difficult to explain. The most likely explanation appears to be that the two ladies named Ida were first cousins, each only children, and that in 1125 they were the only living descendants of their unknown ancestor from whom they had jointly inherited their interest in the property which was the subject of the 1125 charter.
     "No primary source has been identified which links either Ida to the Ath family. Boussu’s mid-18th century history of Ath is the earliest secondary source so far identified which makes the connection. Boussu’s text is confused, stating firstly that “Rase de Gavre” married “Ide d’Ath, seconde fille de Wautier Seigneur d’Ath” and claimed rights to Ath “du chef de sa mère, de même que de sa tante Beatrix”, and secondly that this “Rase de Gavre” was son of “Rase de Gavre, second époux d’Ide dame et héritière de Chièvres”[562]. Van Overstraeten names “Ide d’Ath” (mother of “Ide dite Domison de Chièvres”) and “Ide de Chièvres” (mother of Nicolas Bishop of Cambrai, son of Gossuin [II] de Mons) as joint founders of Ghislenghien[563]. It should also be noted that Bertha de Gavre, grandaughter of Ida wife of Guy de Chièvres, married Eustache [II] Seigneur de Rœulx, grandson of Béatrix d’Ath wife of Arnoul de Hainaut: if Ida and Béatrix had been sisters, the family relationship between husband and wife would have required a Papal dispensation.
     "Pending the emergence of further source material which indicates their family origins, the two ladies are shown below in the Ath chapter for convenience.

; Per Genealogics:
     "Geoffroy was the son of Haymon. According to the cartulary of the abbey of Saint-Vincent, dating between 1067 and 1070, he or more probably his father had his ownership of the château of Mayenne confirmed by Foulques III 'Nerra', comte d'Anjou, between 1014 and Foulques' death in 1040. Haymon subscribed a charter dated 1014 'Signum Haymonis de Medano', so he appears to have been castellan or seigneur already at that time. Geoffroy is first recorded as lord of Mayenne in a charter of Hugues IV, comte de Maine, dated the 20th year of the reign of Henri I, king of France, i.e. approximately 1051.
     "Before 1059 Geoffroy married Mahaut d'Alluye, widow of Guillaume I Gouët, seigneur de Montmirail, and daughter of Gautier d'Alluye. Their son Gautier would have progeny, marrying Adeline (Alix) (de Presles). The marriage of Geoffroy and Mahaut was partly driven by the need to defend against the encroachments of the Normans and of Rotrou I, comte du Perche.
     "Herbert II, comte de Maine, driven from Maine by Geoffrey II Martel, comte d'Anjou, had no sons, and named William the Conqueror, duke of Normandy, as his heir. On Herbert's death in 1062 William pressed his right to succeed in Maine. Most of the lords of Maine revolted against him. Led by Geoffroy they summoned as their new count Gautier III, comte d'Amiens et du Vexin. William of Normandy then embarked on the conquest of Maine, using scorched earth tactics and conquering the castles of his opponents one by one, capturing Gautier who died shortly after in mysterious circumstances. William also laid siege to the castle of Mayenne, to which Geoffroy had fled. When the castle was set on fire it surrendered in 1063.
     "In 1094 Geoffroy allied with Guillaume II de Sillé and the principal lords of Maine to support the house of Giroie in its feud against Robert de Bellême, 3rd earl of Shropshire and of Shrewsbury.
     "Geoffroy died in 1098."⁸

; Per Med Lands: "The parents of the brothers Geoffroy [II] and Hugues de Mayenne have not been satisfactorily identified. It is chronologically improbable that Geoffroy [II] was the same person as Geoffroy [I] Seigneur de Mayenne. It is more likely that the brothers were sons of Geoffroy [I], younger brothers of Gauthier [I], but this is speculation until more primary source documentation emerges."
     "GEOFFROY [II] de Mayenne (-[May/Dec] 1098). Seigneur de Mayenne. The Chronique de Normandie, based on le Roman de Rou, names "Geffroy sire de Maienne" among those who took part in the conquest of England in 1066[348].
