  • Notes 
    • In 1903 Alfred Richard proposed that the Dangereuse who was wife to Aymeric I of Châtellerault was the Dangerosa who occurs as a daughter of Barthelemy de l'Isle-Bouchard and his wife Gerberge in a charter ascribed by its editor to roughly 1087. In a charter dated 1109, Aimery I of Châtellerault names his wife as Dangerosa but says nothing about her parentage. As Peter Stewart pointed out in a post to SGM on 26 Feb 2021, this doesn't add up to proof, although it (Stewart's words) "does seem reasonably likely."

      The fact that her Wikipedia article is titled "Dangereuse de l'Isle Bouchard", as if this parentage were an established fact, does Wikipedia no credit.

      She was also called La Maubergeonne; Amauberge. The latter may have been her actual baptismal name.

      She was mistress to William IX of Aquitaine, father of her son-in-law, in a spectacularly public affair that encompassed papal condemnation and a great deal of other medieval melodrama. The fact that she was Eleanor of Aquitaine's maternal grandmother, and he was Eleanor's paternal grandfather, has only served to add further sizzle to the tale.
