The settlement grew rapidly and soon the residents requested the intervention of the Bishop of Guadalajara so that a church could be built and dedicated to St Matthew. De León distributed the estate to his children and one of them, Alonso de León González ("The younger"), established his property in the northern banks of the Pilón River, organized an outpost and dedicated it to Our Lady of Regla, a black Madonna venerated by Catholics in Chipiona, Cádiz. In 1637, Governor Martín de Zavala promised a large tract of land in central Nuevo León to Captain Alonso de León on condition that, in less than a year, a colonial settlement is built and populated inside its borders.
