  General Notes:

PIERRE de Poitou (1023-1058, bur Poitiers, Priory of St Nicholas). 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. He adopted the name GUILLAUME, "Willelmus filii mei" being named in the charter of his mother Agnes dated 1031. . He succeeded his half-brother in 1039 as GUILLAUME VII "Acerrimus/l'Aigret" Duke of Aquitaine, GUILLAUME V Comte de Poitou, under the regency of his mother until 1044. Geoffroy II "Martel" Comte d'Anjou (formerly Duke Guillaume's stepfather) invaded Poitou in 1053. "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.

m (1051) ERMESINDE, daughter of --- (-after 1062). The Chronicle of Saint-Maxence names "Ermenseldim" as the wife of "Guillelmus Pictavorum dux et comes". The Chronicon Vindocinense records that "comes…Willelmus Pictavorum" married in 1051 but does not name his wife. "Ermensendis uxoris eius" subscribed the charter of "Willelmus Aquitanorum dux, comes autem Pictavorum" dated [1050]. "W dux Aquitanorum…germano illius Gauzfrido" donated property to Saint-Maixent by charter dated 20 Dec [1045] subscribed by "W ducis sueque coniugis Hermensendis, Agnetis comitisse…". "[Name omitted]…comitis" donated property to Saint-Maixent "pro anime sue salute ac matris sue Agnetis ac venerabilis Ermensedis uxoris suæ" by undated charter subscribed by "Goffridi comitis". Settipani suggests that Ermesinde may have been the daughter of Bernard II Comte de Bigorre & his first wife Clémence, based solely on onomastics. She became a nun at Rome with her sister-in-law Empress Agnes.

Duke Guillaume VII & his wife had one child: Agnes.

Pierre married Ermesinde in 1051.1 (Ermesinde died after 1062 1.)
