From 1609 to 1627, Mary Poyntz lived and worked alongside Mary Ward. She accompanied her on several journeys between England and Rome during this period. In 1627 Mary Poyntz was appointed the first superior of the community in Munich, and in the late 1630's she once again accompanied Mary Ward on her return to England. When Mary Ward died in 1645, Mary Poyntz and Winifred Wigmore moved to Paris and worked on the first biography of Mary Ward. Mary Poyntz was appointed as successor to Barbara Babthorpe as chief superior in Rome. In 1667, she died and is buried in Munich in an unmarked grave.
