About Guillaume d'Auvergne

FMG: http://fmg.ac/Projects/MedLands/AQUITAINE NOBILITY.htm

son of Guy Comte d'Auvergne and Ausenda:

[GUILLAUME [IV] (-[1016]). The primary source which confirms the parentage of Comte Guillaume has not so far been identified. Comte d'Auvergne. 1010/1013.]

m HUMBERGE, daughter of ---. "Umberga" donated property to Sauxillanges for the souls of "senioris mei Vuillelmi et…filiorum meorum tam vivis quam etiam defunctis" by charter dated to [1000/10][116]. "Domni Stephani episcopi, domni Rotberti, domni Vuillelmi, Umbergane comitisse matris eorum" signed a charter dated to [1013/21] under which property was donated to Sauxillanges[117]. There is doubt about Humberge's parentage, but she may have been HUMBERGE, daughter of ETIENNE de Brioude & his second wife Adelais [Blanche] d’Anjou, a hypothesis which appears to provide a good solution to various chronological difficulties posed by references in different primary sources. The Flandria Generosa names "Ermengardis comitissa Arvenensis" as sister of "Constantia regina Francorum", when outlining the basis for the consanguinity between their great-great-grandchildren, Baudouin VII Count of Flanders and [Hawise] de Bretagne, which provided the grounds for the couple's separation[118]. It has been assumed in many secondary sources[119] that this passage means that "Ermengarde" was the full sister of Queen Constance (who was the third wife of Robert II King of France) and therefore that she was the daughter of Guillaume [II] Comte de Provence by his second marriage to Adelais d'Anjou. However, this is chronologically impossible. The marriage of "Ermengarde's" daughter, also named Ermengarde, to Eudes II Comte de Blois, is dated to 1005 according to the Chronicle of Alberic de Trois Fontaines[120]. Even if this date is inaccurate, the estimated birth date of Ermengarde junior's eldest son is [1010], and the marriage of her daughter is dated to 1018 (although the chronology suggests that this may have been an infant betrothal or marriage). Assuming that there is a degree of accuracy in these three dates, the daughter of "Ermengarde" Ctss d'Auvergne could not have been born later than [995] at the latest. This places the birth of "Ermengarde" senior to [980] at the very latest, about five years before Adelais's marriage to Guillaume Comte de Provence. Given that Adelais's third marriage to Louis V King of the West Franks was childless, and her second marriage to Raymond IV Comte de Toulouse was brief, it is therefore most likely that "Ermengarde" was Adelais's daughter by her first marriage to Etienne de Brioude. Some corroboration for this hypothesis is found in the charter dated 1011 under which "Poncius comes Gabalitanensis" (who was the son of Adelais d'Anjou by her marriage to Etienne de Brioude) donated property to Saint-Julien de Brioude for the souls of "uxoris eius Theotbergæ et filiorum eius Stephani et Poncii…nepotum eius Stephani, Rotberti et Vuillelmi" by charter dated 1011, subscribed by "Stephanus vicecomes, Rotberti vicecomitis, Vuillelmi fratris eius"[121]. In this scenario, Etienne, Robert and Guillaume would be the sons of Pons's full sister "Ermengarde" Ctss d'Auvergne. However, this raises yet more difficulties. The secondary sources also assume that "Ermengarde's" husband was Robert [I] Comte d'Auvergne. However, the only known son of Comte Robert [I] was Guillaume [V] Comte d'Auvergne. Assuming that the "nepotes" of Comte Pons are named in order of seniority in the 1011 charter, "Vuillelmi" would have been the youngest brother. No other reference has been to found to his assumed older brothers Etienne and Robert. In any case, it is unlikely that Guillaume [V] Comte d'Auvergne would have been born much before [995/1000] for consistency with the dates of his marriage and his death. If this is correct, it would raise doubts about the use of the title "vicecomes" in the 1011 charter, as their father would still have been at the height of his power. All these difficulties would be solved if the "nepotes" of Comte Pons were in fact the three known sons of Guillaume [IV] Comte d'Auvergne, not of Robert [I] Comte d'Auvergne. If this is correct, "Ermengarde" would in fact have been "Humberge", who, as shown above, is named in other primary sources as the wife of Comte Guillaume.

Comte Guillaume [IV] & his wife had four children:

a) ROBERT [I] d'Auvergne (-before 1032). "Poncius…comes…Gabalitanensis" donated property to Saint-Julien de Brioude for the souls of "genitorum meorum Stephani et Alaiz et uxoris meæ Theotberganæ et filiis meis Stephani et Poncii, vel fratribus meis Bertrando et Villelmo et nepotibus meis [Stephanum], Robertum atque Villelmum" by charter dated Feb 1011, subscribed by "Stephanus vicecomes…Rotberti vicecomitis, W. fratris sui…"[122]. "Domni Stephani episcopi, domni Rotberti, domni Vuillelmi, Umbergane comitisse matris eorum" signed a charter dated to [1013/21] under which property was donated to Sauxillanges[123]. Comte d'Auvergne. m ---. The name of Comte Robert [I]'s wife is not known. As explained above under his mother Humberge, it is unlikely that she was Ermengarde, daughter of Adelais d'Anjou, either by her first husband Etienne de Brioude or by her fourth husband Guillaume [II] Comte de Provence. Comte Robert [I] & his wife had one child: i) GUILLAUME [V] (-after 23 May 1059).

b) ETIENNE (-killed in battle 1013). "Poncius…comes…Gabalitanensis" donated property to Saint-Julien de Brioude for the souls of "genitorum meorum Stephani et Alaiz et uxoris meæ Theotberganæ et filiis meis Stephani et Poncii, vel fratribus meis Bertrando et Villelmo et nepotibus meis [Stephanum], Robertum atque Villelmum" by charter dated Feb 1011, subscribed by "Stephanus vicecomes…Rotberti vicecomitis, W. fratris sui…"[140]. "Domni Stephani episcopi, domni Rotberti, domni Vuillelmi, Umbergane comitisse matris eorum" signed a charter dated to [1013/21] under which property was donated to Sauxillanges[141]. Bishop of Clermont 1010.

c) GUILLAUME . "Poncius…comes…Gabalitanensis" donated property to Saint-Julien de Brioude for the souls of "genitorum meorum Stephani et Alaiz et uxoris meæ Theotberganæ et filiis meis Stephani et Poncii, vel fratribus meis Bertrando et Villelmo et nepotibus meis [Stephanum], Robertum atque Villelmum" by charter dated Feb 1011, subscribed by "Stephanus vicecomes…Rotberti vicecomitis, W. fratris sui…"[142]. "Domni Stephani episcopi, domni Rotberti, domni Vuillelmi, Umbergane comitisse matris eorum" signed a charter dated to [1013/21] under which property was donated to Sauxillanges[143]. Comte d'Auvergne. 1010/1015.

d) 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).
