  Research Notes:

The Chronicle of Saint-Maxence records the birth "1071 XI Kal Nov" of "Goffredo duci…Guillelmus filius". "Willelmi filius eius" subscribed the donation by "Willelmus dux Aquitanorum" of property to St Cyprien, Poitiers by charter dated [1073/87]. "Goffredus…dux Aquitanorum et Guillelmus filius eius" set entry conditions for monks at Saint-Hilaire de Poitiers by charter dated 1078 or 1079.

He succeeded his father in 1086 as GUILLAUME IX Duke of Aquitaine, GUILLAUME VII Comte de Poitou. Albert of Aix records that "Willelmus comes et princeps Pictaviensium, de sanguine et origine Henrici tertii imperatoris Romanorum" crossed Hungary peacefully with "duce Bawariorum Welfone et…comitssa…Ida de marchia Osterrich", entered the territory of the Bulgars in which "duce Bulgarorum Guz" refused their passage into Adrianople (when "Rodulfus…de Scegonges ortus, cognatus ipsius Willelmi principis" was killed and "Hardewinus…de Sancto Medardo" captured), but that Guillaume captured "ducem Bulgarorum" who was forced to allow the pilgrims to continue, undated but in a passage adjacent to text which records events in 1101. According to Albert of Aix, after the army was dispersed in Asia Minor by the Turks, Duke Guillaume fled to "Longinath juxta Tursolt civitatem", from where he was rescued and brought to Antioch by Tancred's forces. "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".

He was a troubadour and composer of lyric poetry.

The Chronicle of Saint-Maxence records the death "1126 IV Id Feb" of "Willelmus dux Aquitanorum" and his burial "Pictavis civitate apud Novum Monasterium". The necrology of the Prieuré de Fontaines records the death "10 Feb" of "Guillermus dux Aquitanorum". 1
