Quem namorou Guilherme IX da Aquitânia?

Guilherme IX da Aquitânia, o Trovador (22 de outubro de 1071 – 10 de fevereiro de 1126) foi Duque da Aquitânia e da Gasconha e Conde de Poitiers (como Guilherme VII) entre 1086 e 1126. Foi também um dos líderes da Primeira Cruzada e um dos primeiros trovadores e poetas vernaculares.

Dangereuse of L'Île-Bouchard (Poitevin: Dangerosa; 1079 – 1151) was the daughter of Bartholomew, Lord of L'Île-Bouchard and his wife Gerberge of Blaison. She was the maternal grandmother of Eleanor of Aquitaine. She was also mistress to her granddaughters' paternal grandfather, William IX, Duke of Aquitaine. As the mistress of William the Troubadour, she was known as La Maubergeonne for the tower he built for her at his castle in Poitiers.

Dangereuse ("Dangerous") was a sobriquet she received for her seductiveness; her baptismal name may have been Amauberge or Amal(a)berge.
