Éléonore de Montfort

Éléonore de Montfort was the daughter of Philippe II de Montfort, lord of Castres, and Jeanne de Lévis-Mirepoix. Around 1285 she married Jean V, Count of Vendôme, bringing him the lordship of Castres in Albigeois; Jean preferred to reside there, and the counts of Vendôme thereafter held Castres.

Her children included Bouchard VI, who succeeded his father in Vendôme and Castres in 1315, and Jeanne, who married Henri IV de Sully. She was still living after 1338.
