Joined the Cistercian Abbey of Boulancourt at Longeville, France when still very young. Noted for her deep prayer life, fasts, and austere, sometimes severe self-imposed penances such as wearing a pointed chain under her habit, walking barefooted throughout the year and fasting from food and liquids three days a week. Word of her devotion soon spread, and pilgrims came to consult her about holiness and prayer. She had the gift of prophesy, and sometimes prophesied about visitors before they arrived. She never sought honor or glory for herself from her gifts, but dealt with visitors humbly and patiently, always concerned with their conversion and relationship with God.
