In 1953 Fr. William Wasson was ordained a priest and worked in a small parish in Cuernavaca, Mexico. In August 1954, a boy was arrested for stealing from the poor box of his church. He was arrested and went to jail where Fr. Wasson visited him. He found out that Gustavo had taken the money because he was hungry.
Fr. Wasson was unwilling to press charges against the boy and instead asked for custody of him. Little later, the judge sent him more children. That was when Nuestros Pequeños Hermanos was born.
