Helena, mother of Constantine the Great (died 330CE)
Helena, mother of Constantine I (died 18 August 330CE). Flavia Iulia Helena Augusta, wife of Constantius I, is also known as Saint Helena and Helena of Constantinople. She is credited with finding the relics of the True Cross and is the patron saint of new discoveries. Although it was at her behest that Constantine executed his wife, Fausta, Helena's piety and saintliness has never been questioned.
