Background
She was the second daughter of Madame Acarie, the Blessed Marie of the Incarnation, who introduced the Reform of the Carmelite Order into France. Born Margaret Acarie, her father, Pierre Acarie, was one of the staunchest members of the Catholic League, which, after the death of King Henry III of France, opposed the succession of the Huguenot prince, Henry of Navarre, to the French throne.
Career
He was one of the 16 who organized resistance to this in Paris. Directed by Pierre de Bérulle, she took the religious habit at the first Discalced Carmelite convent in France, on the Rue Saint 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.
Sister Margaret was then sent in 1621 to restore harmony in the monastery at Bordeaux.
Shortly after this she was ordered to the monastery of Saintes, where she remained for 18 months. In 1624 she was recalled to Paris, to replace as prioress Mother Madeleine de Saint-Joseph in the monastery situated on the Rue Chapon.
After having been several times prioress of that monastery, where she showed a zeal for bodily mortification that her superiors had sometimes to moderate, she developed dropsy, of which she died. Margaret"s heart was taken to the monastery at Pontoise, where her mother had been buried, and her body remained in the monastery on Rue Chapon, where it was kept until 1792.
