Saint Margaret Mary Alacoque is invoked as patron of devotees of the Sacred Heart of Jesus. Marguerite Alacoque was born at Verosvres in Burgundy on 22 July 1647. After a childhood of illness and the early death of her father, she entered the Visitation monastery of Paray-le-Monial in 1671, taking the name Margaret Mary at her religious profession in 1672.
