Born: 17 Oct. Also "Marguerite-Marie Alacoque."
From Butler's Lives of the Saints 1894:
MARGARET MARY was born at Terreau in Burgundy, on the 22d July, 1647. During her infancy she showed a wonderfully sensitive horror of the very idea of sin. In 1671 she entered the Order of the Visitation, at Paray-le-Monial, and was professed the following year. After purifying her by many trials, Jesus appeared to her in numerous visions, displaying to her His Sacred Heart, sometimes burning as a furnace, and sometimes torn and bleeding on account of the coldness and sins of men. In. 1675 the great revelation was made to her that she, in union with Father de la Colombière, of the Society of Jesus, was to be the chief instrument for instituting the feast of the Sacred Heart, and for spreading that devotion throughout the world. She died on the 17th October, 1690.
