REGINAR [II], son of REGINAR [I] "Langhals/Longneck" Graf im Maasgau & his wife Alberade --- ([885/900]-932 or after). The Annales Hanoniæ name "Raginerus" as son of "Raginerus dictus Longi-colli"[26]. Flodoard names "Ragenarii, fratris ipsius Gisleberti"[27]. Charles III "le Simple" King of the West Franks restored Kloster Süsteren to the abbey of Prüm by charter dated 19 Jan 916 which names "fidelium nostrorum…Widricus comes palatii, Richuuinus comes, Gislebertus, Matfridus, Beringerius comites, Theodericus comes, Reinherus comes, Erleboldus"[28]. A document dated 7 Nov 921 recording a meeting between King Charles III "le Simple" and Heinrich I King of Germany names "Matfredus, Erkengerus, Hagano, Boso, Waltkerus, Isaac, Ragenberus, Theodricus, Adalardus, Adelelmus" as representatives of the former[29]. It is not certain that "Ragenberus" refers to Reginar [II] Comte de Hainaut. Flodoard's Annals record that "Berengarius" captured "Giselbertum" and only freed him after receiving "filiis Ragenarii fratris ipsius Gisleberti" as hostages, after which Giselbert ravaged the lands of "Berengarii, Ragenariique fratris sui et Isaac comitis"[30]. The primary source which confirms that Reginar [II] was Comte de Hainaut has not yet been identified. "Otto…imperator augustus" confirmed the donations to the convent of Nivelles by "Regenarius comes" of property "in pago Ardenna super fluvia Aisna in comitatu Waudricia in villa Villaro" and by "predicti Regenarii filius nomine Liechardus in pago Hasbanensi in villa Gingolonham", by "Rodolphus comes villa Lentlo", by "Hillinus…in villa…Gislebrertruoz…pro anima Gisloberti genitoris sui", and by "Robertus uxorque eius…Geua cum filio suo Regennario…in pago Hainau in villa…Hayna" by charter dated 24 Jan 966[31]. This document presumably refers to Comte Reginar [II], as his son Reginar [III] was living in exile at the date of the charter.
m ---. No reference has been found to the name or origin of the wife of Comte Reginar [II]. However, the introduction of the name Lietard into the Hainaut family after this marriage suggests that she may have been related to the family of the comtes de Huy (see LOWER LOTHARINGIAN NOBILITY). If this is correct, she was --- [de Huy], daughter of ---. This would also explain why her grandson became comte de Louvain, which formed part of the territories relinquished by Ansfrid [II] Comte de Huy when he was appointed bishop of Utrecht in 995. Dhondt suggests that the wife of Reginar [III] was the sister of Comte Ansfrid [II], whose father was named Lambert, the name given by Reginar [III] to his younger son. In addition to the onomastic arguments, Dhondt comments that the voogdij of Gembloux abbey passed from Ansfrid [II] to Lambert [I] de Hainaut[32]. This provides an additional argument for a family relationship between the comtes de Huy and the comtes de Hainaut. However, Dhondt´s suggestion does not explain the introduction of the name Lietard into the Hainaut family. On balance, it appears more likely that such a family connection was through the wife of Reginar [II] rather than the wife of Reginar [III]. If this is correct, it is possible that the wife of Reginar [II] was the paternal aunt of Ansfrid [II]. Comte Reginar [II] & his wife had four children
