Directed by Pierre de Bérulle, she took the religious habit at the first Carmelite convent, Rue St. Jacques, Paris, 15 September, 1605. On 21 November, 1606, she made her vows privately, and on 18 March, 1607, she made them solemnly, under the care of Mother Anne de Saint-Barthélemi.
In 1615 she was made sub-prioress, and in 1618, prioress of the convent of Tours. She was sent in 1620 to restore harmony in the convent at Bordeaux. Shortly after this she was ordered to the convent of Saintes, where she remained eighteen months, and in 1624 was recalled to Paris, to replace as prioress Mother Madeleine de Saint-Joseph in the convent situated in the Rue Chapon. After having been several times prioress of the convent of the Rue Chapon, where she showed a zeal for bodily mortification that her superiors had sometimes to moderate, she was attacked by dropsy, of which sh died. Her heart was taken to the monastery of Pontoise, where her mother had been buried, and her body remained in the convent of the Rue Chapon, where it was kept until 1792.
