  General Notes:

GUILLAUME de Poitou, son of GUILLAUME IV "Fier-à-Bras" Duke of Aquitaine [GUILLAUME II Comte de Poitou] & his wife Emma de Blois ([969]-Maillezais 31 Jan 1030, bur Maillezais, Abbaye de Saint-Pierre). The Chronicle of Adémar de Chabannes names "Willelmum" as son of "Willelmum" (son of "Willelmo Capite stupæ") and his wife "filiam Tetbaldi Campenensis…Emmam". "Vuillelmus dux Aquitanorum" donated property to Saint-Jean d'Angély for the soul of "…filios meo Vuilelmo…" by charter dated [971]. "Willelmus Aquitanorum comes et dux et uxor mea Hemma et filius noster equivocus Willelmus" donated property to Saint-Maixent by charter dated Dec 992. His mother retained custody of Guillaume during her separation from his father, but returned him to Poitiers in May 988. "Guilelmus Aquitaniencum dux" founded a hospital near Saint-Hilaire de Poitiers by charter dated Jan 989, subscribed by "Emma comitissa, Guillelmi filium eius, Guilelmi comitis Engolismæ…". He succeeded his father in 993 as GUILLAUME V "le Grand"Duke of Aquitaine, GUILLAUME III Comte de Poitou. He summoned a council at Poitiers in 1000 which decided that future disputes should be settled by justice not recourse to arms. Duke Guillaume enjoyed close relations with Emperor Heinrich II, with whom he exchanged gifts. Rebels in Italy, opposed to the election of Konrad II King of Germany in 1024, offered the throne of Italy to Duke Guillaume, who refused the offer. Duke Guillaume maintained an active correspondence with leading churchmen, men of science and political leaders and established a library for which he commissioned the transcription of manuscripts. He abdicated in favour of his eldest son in 1029 and became a monk at the Abbey of Maillezais.

m firstly ([997]) as her second husband, ADALMODE de Limoges, widow of AUDEBERT I Comte de La Marche et du Périgord, daughter of GERAUD Vicomte de Limoges & his wife Rothilde de Brosse (-after 1005). The Chronicle of Adémar de Chabannes records that "Aldebertus frater [Helias Petragoricensi comite]" married "sorore Widonis vicecomitis". Ademar records the second marriage of "Adalmode coniuge…Aldeberti" to Duke William. The Chronicle of Petrus Malleacensis records that Adalmodis was wife of Boson Comte du Périgord and daughter of "Candida", for whom Duke Guillaume promised to expand "fluvium Rhodanum Regni" in return for marrying her daughter, but this is not consistent with the other sources. According to the Chronicle of Maillezais, Adalmode was the daughter of Adelaide d'Anjou (presumably by her first husband Etienne de Brioude/Gévaudan), and also widow of Boson Comte du Périgord (brother of Comte Audebert I, whom he survived by several years). Thierry Stasser has shown that this is incorrect. After her first husband was killed, Adalmode sought refuge in the château de Rochemeaux but was forced to surrender by Poitevin forces.

m secondly (1011 before 10 Mar) SANCHA [Brisca] de Gascogne, daughter of GUILLAUME SANCHE Duke of Gascony & his wife Urraca de Navarra (-before 1018). The Chronicle of Adémar de Chabannes names "Briscam" as sister of "dux Santii", when recording her marriage to "Willelmi ducis" after the death of the latter's first wife. The Chronicle of Saint-Maixent names "sororem Sancii Ducis Gasconiæ, nomine Briscam" as second wife of Duke Guillaume, in a later paragraph recording the death of "Sancia conjuge Guillermi ducis". "Willelmi ducis Aquitanorum, Willelmi filii eius, Odoni filii eius, Prisca comitisse" subscribed the charter dated to [1012/18] under which "Ugo Liziniacensis domnus" donated property to St Cyprien, Poitiers. An agreement between the abbots of Jumièges and Bougeuil concerning an exchange of land in Poitou, by charter dated [13 Apr/4 Apr] 1012, is subscribed by "Richardus…filius Ricardi principi magni…Vuillelmus Pictavorum comes et uxor Prisca…".

m thirdly (1019) as her first husband, AGNES de Mâcon, daughter of OTHON GUILLAUME Comte de Mâcon [Bourgogne-Comté]& his first wife Ermentrude de Roucy ([990/95]-Saintes 10 Nov 1068, bur Poitiers, Priory of Saint-Nicolas). Agnes is named as daughter of "Ermentrudis" in the Continuator of Flodoard, which specifies that she was mother of "Wido". Rodulfus Glaber states that "Willemus…Pictauensis" married one of the daughters of "Willemus, Henrici ducis priuignus, Adalberti Longobardorum ducis filius" & his wife. "Agnes comitissa filia Ottonis cognomento Willelmi comitis Matiscensis, uxor…Wilelmi ducis Aquitanorum" donated property to Cluny by charter dated [1020]. She married secondly (1 Jan 1032, repudiated [1049/52]) Geoffroy "Martel" d'Anjou (-9 Nov 1067), who later succeeded as Geoffroy II Comte d'Anjou. The Chronico Sancti Michaelis records that "Gaufredus Martellus Andegavensis comes" married "Agnetem comitissam Pictavensem" incestuously in 1032. The Chronicæ Sancti Albini records the marriage "1032 Kal Jan" of "Gaufridus comes, Agnetem comitissam incesto", indirectly indicating her origin in a later passage which records the marriage "1043 XII Nov" of "Hainricus imperator [et] filiam Agnetis comitissæ". Her origin is clarified by the Chronicæ Sancti Albini which records the marriage "1043 XII Kal Nov…apud Vesbrianim" of "Henricus imperator…filiam Willelmi comitis Pictavorum et Agnetis". Geoffroy Comte d'Anjou & his wife founded the abbey of La Trinité de Vendôme by charter dated 31 May 1040, signed by "Goffridi comitis Andegavorum, Agnetis conjugis suæ…". A powerful personality, she succeeded in defeating her stepson Duke Eudes and installing her own son as Duke of Aquitaine, Comte de Poitou. Regent of Aquitaine for her son 1039-1044. She arranged her daughter's marriage with Emperor Heinrich III in 1043 and lived at the imperial court after this time. "Goffredus…comes atque Agnes…uxor" donated property to the monks of La Trinité, Vendôme by charter dated 6 Jan 1049 subscribed by "Willelmi ducis Aquitanorum, Goffredi pueri fratris illius". "Gaufredus Andegavorum comes…uxor mea Agnes" made a donation to the priory of Saint-Nicholas de Poitiers by undated charter which also names "eius [Agnetis] filii comites…Pictavenses". A charter dated to [1060/67] recites a prior donation to Saint-Aubin d'Angers by "Hildegardis comitissa", who retained a life interest in the property which, after the death of the donor, was sold in turn to "Agneti comitissa" (recording her divorce from "comitum Gaufridum"), "comitem Gaufridum…Gaufridi nepotem" and finally "fratre eius Fulconi" who restituted it to the abbey. After her separation from her second husband, in 1047 she founded the abbey of Notre-Dame de Saintes, where she became a nun in 1068. "Agnes" founded the abbey of Saint-Nicolas at Poitou with the consent of "ambobus filiis Guillelmi et Gauffrido" by charter dated [1050]. "Aquitanorum…dux Gaufridus" confirms in his charter dated [1058/68] that "mea mater Agnes…frater meus Guillelmus" were both buried in the priory of Saint-Nicolas de Poitiers. The necrology of Vendôme La Trinité records the death "IV Id Nov" of "Agnes comitissa".

Duke Guillaume V & his first wife had [two children]: Guillaume and [Alix].

Duke Guillaume V & his second wife had two children: Eudes and Thibaut.

Duke Guillaume V & his third wife had [three] children: Pierre, Guy, and Agnes. Possibly also [Beatrix] and [Adelais].

Beatrix is named as one of the children of Duke Guillaume V & his third wife in Europäische Stammtafeln but the primary source on which this is based has not yet been found. She is not named among the children of Duke Guillaume V by Richard. If she was the daughter of Duke Guillaume, it seems surprising that she was married to a relatively obscure local nobleman, especially in light of the high profile marriage of her supposed sister Agnes.

According to Europäische Stammtafeln, a fifth child Adelais married firstly Géraud [I] "Trencaléon" Comte d'Armagnac and secondly Arnaud [II] Vicomte de Lomagne, but this is clearly impossible chronologically given the death of Comte Géraud in [1014].


Guillaume married Adalmode de Limoges about 997. (Adalmode de Limoges died after 1005.)


Guillaume next married Sancha de Gascogne before 10 Mar 1011. (Sancha de Gascogne died before 1018.)


Guillaume next married Agnès de Mâcon, daughter of Guglielmo di Ivrea Comte de Mâcon et de Nevers and Ermentrude de Roucy, in 1019. (Agnès de Mâcon was born between 990 and 995, died on 10 Nov 1068 in Saintes, Charente-Maritime, Poitou-Charentes, 17100, FR and was buried in Abbaye de Saint Nicolas de Poitiers, Poitiers, Vienne, Poitou-Charentes, 86000, FR.)
