By the will of her father she married at 17 M. Martin, a silk manufacturer. Having been left a widow at 19, she superintended a factory till her son was 12 years of age. and then, on Jan. 25, 1631, entered an Ursuline convent. She went to Canada in 1639, and founded the Ursuline convent in Quebec. She acquired tin-Huron and Algonquin languages, taught French and Indian pupils, and evinced great judgment and ability in directing her community and in aiding the rising colony. She was one of the first to call the attention of the French government to the vital importance of securing the mouth of the Hudson from the Dutch, if France desired to hold Canada. Her letters, which form a valuable body of contemporaneous information, and are esteemed in a religious point of view, were published in 1681. Her life has been written by her son, the Benedictine Dom Claude Martin (Paris, 1677), by Father Charlevoix (Paris, 1724), and by the abbe Casgrain (Quebec, 1864).
