Rodrigo de Cepeda, four years older than the Saint, entered the army, and, serving in South America, was drowned in the river Plate, Rio de la Plata. St. Teresa always considered him a martyr, because he died in defence of the Catholic faith (Ribera, lib. i. ch. iii.). Before he sailed for the Indies, he made his will, and left all his property to the Saint, his sister (Reforma de los Descalços, vol. i. lib. i. ch. iii. § 4).
