  Research Notes:

Agnes is named as daughter of "Ermentrudis" in the Continuator of Flodoard, which specifies that she was mother of "Wido". Her birth date range is estimated on the basis of the estimated birth date range of her mother. 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].

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 installed 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 restored 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". 1
