Saint Teresa was born in Avila, Spain, March 28, 1515. She died in Alba, October 4, 1582. Her family origins have been traced to Toledo and Olmedo. Her father, Alonso de Cepeda, was a son of a Toledan merchant, Juan Sanchez de Toledo and Ines de Cepeda, originally from Tordesillas. Juan transferred his business to Avila, where he succeeded in having his children marry into families of the nobility. In 1505 Alonso married Catalina del Peso, who bore him two children and died in 1507. Two years later Alonso married the 15-year-old Beatriz de Ahumada of whom Teresa was born.
