Another name for Guy was Geoffroy d'Aquitaine.
GUY d'Aquitaine, son of GUILLAUME V "le Grand" Duke of Aquitaine [GUILLAUME III Comte de Poitou] & his third wife Agnès de Mâcon [Bourgogne-Comté] (1023-Chizé near Niort, Poitou 25 Sep 1086, bur Poitiers, église abbatiale de Saint-Jean l'Evangéliste de Montierneuf). The Chronicle of Saint-Maixent names "Petrum cognomina Acerrimum et Gaufredum qui Wido vocatus est" as the twin sons of Duke Guillaume and his third wife Agnes. "Wido" is named as son of Agnes (daughter of "Ermentrudis") in the Continuator of Flodoard. He adopted the first name GEOFFROY, "Gausfredus filii mei" being named in the charter of his mother Agnes dated 1031. Comte de Gascogne 1039. Comte de Bordeaux et d'Agen 1044. "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". He adopted the first name GUILLAUME when he succeeded his brother in 1058 as GUILLAUME VIII Duke of Aquitaine, GUILLAUME VI Comte de Poitou. He extended his territories, confirming his authority in Gascony and pushing as far as Toulouse. He took part in the capture of Barbastro from the Moors in 1064, although the town was lost soon after. "Goffredus…dux Aquitanorum et Guillelmus filius eius" set entry conditions for monks at Saint-Hilaire de Poitiers by charter dated 1078 or 1079. The Chronicon sancti Florentii Salmurensis records the death in Sep 1086 of "Guido Pictavorum comes". The Chronicle of Saint-Maxence records the death in 1086 of "Guido qui et Goffredus comes Pictavorum".
m firstly (Jan 1044, repudiated 1058) as her second husband, AINA de Périgord, widow of EUDES de Bordeaux, daughter of [BOSON [III] Comte de Périgord & his wife Aina de Montignac] (-after 1058). The Chronicle of Saint-Maxence names "Audeberti comitis Petragoricæ filiam" as the wife of "Gaufredus", specifying that they later separated on the grounds of consanguinity. This is impossible from a chronological point of view if it is assumed the charters dated 1122 naming "Ascelina comitissa" refer to the wife of Audebert [III] Comte de Périgord. It is therefore posited that Aina was the daughter of Boson [III] which, assuming the latter's birth in , is chronologically consistent with her first marriage before 1039. The primary source which confirms her first marriage has not so far been identified, although the charter dated 1043 under which "Ama comitissa Burdagelensis seu Petragorice patrie" donated property in the Dordogne to the monastery of Sainte-Marie-de-la-fin-des-terres suggests that it may be correct. After her repudiation by her second husband, she became a nun at Notre Dame de Saintes where she died.
m secondly (after Nov 1058, repudiated after May 1068) MATHILDE, daughter of ---. The Chronicle of Saint-Maxence names "Mateodam" as the second wife of "Goffredus". Kerrebrouck says that the family origin of Mathilde is unknown but that she may have belonged to the family of the Vicomtes de Thouars, although the basis for this speculation is not known. "Goffridi ducis Aquitanorum, Mathildæ comitissæ…" subscribed the charter dated May 1068 under which "Goscelinus beati Hilarii…thesaurarius" donated the monastery of Saint-Porchaire de Potiers to the abbey of Bourgueil.
m thirdly (Mar 1069, separated 1076) AUDEARDE [Hildegarde] de Bourgogne, daughter of ROBERT I "le Vieux" Duke of Burgundy & his second wife Ermengarde [Blanche] d'Anjou (-after 1120, bur Poitiers, [église abbatiale de Saint-Jean l'Evangéliste de Montierneuf]). The Chronicle of Saint-Maxence records the marriage of "Guido comes" and "Aldeardim filiam Roberti ducis Burgundiæ" after he repudiated his previous wife. Her precise parentage is deduced from a genealogy of the Comtes d'Anjou which names "Fulco (pater) Gosfridus et Ermengardis (mater) Gosfridus (et) Fulco (et) Hildegardis, de altero patre, filia Roberti ducis fratris Henrici regis". "Aimericus de Ranconia vocatus filius Aimeri qui fuit male peremptus et filius Burgoniæ" donated "mariscum et verniatam quæ sunt sub molendino de Ternant" to the abbey of Ternant Ste-Marie by charter dated 1105, witnessed by "Willelmi ducis, Aldiardis comitissa".
Duke Guillaume VIII & his second wife had one child: Agnes.
Duke Guillaume VIII & his third wife had [four] children: Guillaume, Hugues, Agnes and [Beatrix].
Guy married Aina de Périgord in Jan 1044. (Aina de Périgord died after 1058 in Abbaye aux Dames de Saintes, Saintes, Charente-Maritime, Poitou-Charentes, 17100, FR and was buried in Abbaye aux Dames de Saintes, Saintes, Charente-Maritime, Poitou-Charentes, 17100, FR.)
Guy next married Mathilde after Nov 1058.
Guy next married Audéarde de Bourgogne, daughter of Robert de France Duc de Bourgogne and Ermengarde d'Anjou, in Mar 1069. (Audéarde de Bourgogne was born about 1050, died after 1120 and was buried in Église Abbatiale de Saint-Jean l'Evangéliste de Montierneuf, Poitiers, Vienne, Poitou-Charentes, 86000, FR.)
