ERMENGARDE d'Auvergne (-11 or 12 Mar after 1042). The Flandria Generosa names "altera Ermengardis comitissa" as daughter of "Ermengardis comitissa Arvenensis", and mother of "Berta comitissa [=de Blois]", when outlining the basis for the consanguinity between Baudouin VII Count of Flanders and [Hawise] de Bretagne, which provided the grounds for the couple's separation[144]. As discussed above under her assumed mother Humberge, less chronological difficulties result if Ermengarde was in fact the daughter of Guillaume [IV] Comte d'Auvergne. The date of her marriage is fixed by the Chronicle of Alberic de Trois-Fontaines which names "comitissam Turonensem Ermengardem" as wife of "Odonem Campaniensem comitem" when recording in 1005 their joint restoration of "Turonis maioris monasterii"[145]. The necrology of Saint-Père-en-Vallée records the death "IV Id Mar" of "Ermengardis comitissa"[146]. The necrology of Pontlevoy records the death "V Id Mar" of "Ermengardis comitissa"[147]. m (1005) as his second wife, EUDES II Comte de Blois, son of EUDES I Comte de Blois & his wife Berthe de Bourgogne [Welf] ([982/83]-killed in battle Commercy 15 Nov 1037).
