Born in Gramat, France, department of Lot, diocese of Cahors, on 27 October 1824. From a Christian family, middle class.

There, he met Francisco Palau when he was in exile. From the time they met in France in 1845, their lives ran parallel and Jeanne's spiritual path was linked to that of François.

She was part of the small women's group, guided by him. She was the person Father Palau trusted, whom he directed spiritually and gave him the guidelines to gradually form the first Carmelite Missionary Carmelite communities.

Juana remained faithful to Father Palau and always lived in communion with the sisters.

Dies on 24 December 1903.
