She was the daughter of the rich noble Louis d'Amboise, prince of Talmont and Viscount of Thouars, and Louise-Marie de Rieux.

[2] To escape from the violence of the times, she fled with her mother to the court of Brittany, which resided in Vannes and, later on, in Nantes.

At the age of three she had been engaged to Peter, the second son of John V, Duke of Brittany, for political reasons.

She then entered into a conflict with King Louis XI who wanted to marry her.

A widow without children, she founded in 1463, together with Jean Soreth, the first convent of the Carmelites in France, of which she later became prioress.
