Alfonso Sanchez de Cepeda, father of the Saint, married first Catalina del Peso y Henao, and had three children--one daughter, Maria de Cepeda, and two sons. After the death of Catalina, he married Beatriz Davila y Ahumada, by whom he had nine children--seven boys and two girls. The third of these, and the eldest of the daughters, was the Saint, Doña Teresa Sanchez Cepeda Davila y Ahumada. In the Monastery of the Incarnation, where she was a professed nun for twenty-eight years, she was known as Doña Teresa; but in the year 1563, when she left her monastery for the new foundation of St. Joseph, of the Reform of the Carmelites, she took for the first time the name of Teresa of Jesus (De la Fuente). The Saint was born March 28, 1515, and baptized on the 4th of April, in the church of St. John; on which day Mass was said for the first time in the Monastery of the Incarnation, where the Saint made her profession. Her godfather was Vela Nuñez, and her godmother Doña Maria del Aguila. The Bollandists and Father Bouix say that she was baptized on the very day of her birth. But the testimony of Doña Maria de Pinel, a nun in the Monastery of the Incarnation, is clear: and Don Vicente de La Fuente, quoting it, vol. i. p. 549, says that this delay of baptism was nothing singular in those days, provided there was no danger of death.
