Teresa Margaret of the Sacred Heart, OCD (15 July 1747 – 7 March 1770) was an Italian Discalced Carmelite nun. During her brief life of quiet service in the monastery, she came to be revered for her mystical gifts. She has been declared a saint by the Catholic Church. Life She was born Anna Maria Redi to a large noble family in Arezzo, the second child of Count Ignazio Maria Redi and Camilla Billeti. At the age of 9, she was enrolled in the boarding school of the Benedictine monks of the Monastery of St. Apollonia in Florence. When she was older, Redi began to ponder her future.

In keeping with the custom of the time, she then left the monastery for two months and stayed with a friend of the family in the city, while awaiting a formal reply to her petition.
