On August 28, 1912, the community of Guadalajara agreed to found a new community in Mascota, Jalisco. Sister María Teresa Cruz was chosen as Superior. She was joined by two professed Sisters, two novices and two candidates. Several weeks later, they opened a school. Soon they received postulants.

During the Mexican Revolution, the school was sometimes confiscated by the civil authorities. At times, the Sisters had to hide from the fury of the revolutionaries. According to the direction of Bishop Segura, they moved to Tlapa for three years. There they lived more peacefully.

On October 12, 1920, the community left Mascota, and by way of Veracruz, settled in Teziutlán, Puebla, where they soon opened a school. During the religious persecution of 1926, their school was closed, and they had to live in private homes. Because of this, they were separated for a time. In 1928 they were able to open a school for the poor in Puebla.

In January, 1949, with the help of Mother María del Consuelo, the Sisters in Teziutlán received canonical approval of their foundation.
