Émilie d'Oultremont was a Belgian widow who became a religious sister and founded the Sisters of Mary Reparatrix. Born in 1818 at Wégimont Castle, she lived a life of nobility before her husband's death led her toward religious devotion. Following a vision in 1854, she established a community in Paris focused on spiritual retreats and Eucharistic adoration. She expanded her order internationally, sending members to locations such as England and India. She died in Florence in 1878 and was later beatified by Pope John Paul II.
