ROBERT [IV] ["le Gros"] de Béthune ([1050/65]-after 14 Apr 1127). The attribution of different nicknames to Robert [III] and Robert [IV] suggests that they were different people, although the chronology could support co-identity. If that is correct, no primary source has been identified which confirms that Robert [IV] was the son of Robert [III], but that affiliation is probably correct. His nickname is indicated by the undated charter which records that "Robertus Faisceuls" founded the church of Saint-Barthélemy, that after his death "Robertus filius suus" confirmed his father´s foundation, that "Robertus…Grossus pater Guillelmi" built three chapels in one of which "filium suum Robertum fratrem Guillelmi" was buried, that "Robertus Rufus nepos ipsius…et mater eius Clementia" donated property[275]. "Robertus Atrebatensis advocatus...ac filius meus Balduinus" donated "terram...Fauerils et Istels cum sylva" to Mont Saint-Eloi by undated charter, dated to [1093/1108], witnessed by "Simone castellano, Manasse filio Elberti, Balduino fratre eius"[276]. An undated charter records that "Odo...frater ipsius...Fulbertus" donated "de villa...Camblinium...apud Ableuium", held from "Elberto de Bethunia milite", to Mont Saint-Eloi, that after the death of Elbert "Sicherus filius eius" wished to annul the acts of his father but that a settlement was agreed with the consent of "domino Roberto advocato filioque eius Balduino", by undated charter witnessed by "...Hugo filius Wagonis de Bethunia, Manasses, clerici..."[277]. "…Robertus, Bituniensis, Baldus filius eius…" signed the charter dated 15 Feb 1113 under which Baudouin VII Count of Flanders attested that "Walterio Hisdinensi" had committed to defend the abbey of Saint-Silvin d´Auchy[278]. "…Robertus de Betunia…" signed a charter dated 29 Nov 1121 under which Charles Count of Flanders donated property to the monastery of Bourbourg[279]. "…Robertus advocatus de Betune…" witnessed the charter dated 7 Jul 1123 under which "Hugo de Sancto Paulo cognomen habens Campdaveine" donated property to the monastery of Bourbourg, in the presence of Charles Count of Flanders[280]. An undated charter records that "Dominus Robertus Bituniensis et idem advocatus Attrebatensis", after donating "terræ...Fauerils" to Saint-Eloi, wished to retain part of the land himself, witnessed by "Guillelmus filius ipsius Roberti, Sicherus de Carenci, Hugo de Carenci, Robertus frater eius, Elbodo de Carenci"[281]. "…Hosto castellanus et Guillelmus frater eius, Robertus de Bethuna et Guilelmus filius eius, Anselmus de Hesdinio…Rogerus castellanus Insulensis et Robertus filius eius, Razo de Gavera, Daniel de Tenremont…Henricus de Brocborc, Eustachius advocatus et Arnulphus filius Rius castellanus Gandavensis…" signed the charter dated 14 Apr 1127 under which Guillaume Count of Flanders granted privileges to the town of Saint-Omer[282]. mADELISE, daughter of ---. "Robertus...Betuniæ advocatus" settled a dispute with Corbie Saint-Pierre, for the souls of "...meæ...et uxoris meæ Adelisæ et filiorum", by undated charter witnessed by "...De militibus: Ilbertus de Carenci et Robertus frater eius, Ioannes de Beuri, Hugo de Ballolio, Balduinus de Atrebato eiusdem advocati cognatus"[283]. Du Chesne indicates that she was Adelise de Péronne, daughter of Robert Seigneur de Péronne & his wife Emma ---[284]. Several sources confirm that Robert Seigneur de Péronne had a daughter named Adélise (see the document NORTHERN FRANCE NOBILITY). In addition, her husband was named Robert as shown by the charter dated 1095 under which "Robert Sire de Péronne et Aelis sa compagne" donated property to Mont Saint-Quentin abbey[285]. However, Du Chesne cites no source which confirms that Adelise´s husband was the same person as Robert [IV]. In particular, no source has been found in which Robert de Béthune is named as seigneur de Péronne, although Du Chesne does quote other sources in which the Béthune family refers to Warneston (one of the Péronne properties as noted above) and one source dated Jan 1199 at Péronne[286]. Until more information comes to light, it is suggested that this possible co-identity should be viewed with caution. Robert [IV] & his wife had two children:
