  Research Notes:

His mother names her son Guillaume de Toulouse and his wife Emma in an act dated 1021.

He succeeded his father in [978] as GUILLAUME III “Taillefer” Comte de Toulouse. "Dominus princeps et marchio istius provinciæ…Willelmus cum coniuge sua…Adelaix et filio suo…Willelmo" restored property to the abbey of Saint-Césaire d´Arles by charter dated 992, subscribed by "Domnus Rotbaldus comes…Willelmus comes filius Rotbaldi et uxor sua Lucia, Wilelmus comes Tolosanus et uxor sua Ema…". The list of subscribers of this document presents dating difficulties as the last two named couples appear from other primary sources to belong to a later period. The probable explanation is that two lists from two different documents were copied and incorrectly combined. The testament of "Ermengaudus archipresul", dated to [1005], bequeathed property to "…Willelmo comiti Tolosano…". A charter dated to [1006] records the council of the archiepiscopal provinces of Narbonne and Auch held by "Raimundus episcopus Tolosanus et Guillelmus comes Albiensium ac Caturcensium et Tolosanorum" at Toulouse. A bull of "Benedictus episcopus", warning against those who usurped the rights of the monastery of Saint-Gilles, names "Guilelmo comiti necnon matri sue Adelati". The compilation consulted assumes that this bull was issued by Pope Benedict IX, and therefore dated to [1033/44]. It is unlikely that this can be correct, considering the estimated birth date of Comte Guillaume's mother... For chronological consistency, it is more probable that the document was issued by Pope Benedict VIII whose papacy ran from 1012 to 1024. Dating the document to the early years of this papacy would explain explain why the count's mother is named in place of his wife (on the assumption that Guillaume's first wife predeceased the bull, and that it was issued before his second marriage), and would also be consistent with his mother's supposed fifth marriage assuming that this is dated to [1014/16]. "Wilelmi comitis Tholosani…" witnessed the charter dated 18 Dec 1029 which records the foundation of the monastery of Sauve by "Garsindis et filius meus Bremundus et frater eius Almeradus". "Willelmo patri suo, Bertramno…" subscribed the charter dated 14 Sep 1037 under which "Poncius" donated property to "sponse mee Maiore" at the time of their marriage.

An epitaph in Toulouse Saint-Sernin records the burial of "Willelmus comes cognomine Taliafer atque Raimundus Bertrandi", undated. ¹
