Family[edit]

Blanche was born in about the year 1252 in France. She was the only child and 
heiress of Jean de Brienne, Grand Butler of France, and his first wife, Jeanne, Dame

Montfort-l'Amaury from her mother's first marriage to Jean I de Montfort (died 1249 in 
Cyprus). In 1260, Beatrice married Robert IV of Dreux, Count of Dreux, by whom she 
had six children.
