Małgorzata Szewczyk (1828 – 5 June 1905), also known by her religious name Łucja, was a Polish nun and the foundress of the Daughters of the Sorrowful Mother of God – or Seraphic Sisters; she was also a member of the Third Order of Saint Francis. Her life was dedicated to the care of ill people and she even spent a long period to that end in Israel and Palestine before returning to her native Poland where she became a close collaborator of Honorat Kozminski. Her initiatives to aid the poor and those in need included tending to elder women in her apartments or in going to hospitals and in the streets to help those that needed her charitable assistance.
