At the invitation of Carl Kuemin, of St. John's Church in
Joliet, Illinois, the small group of four
sisters moved to that town the following November to begin teaching the local children. Lightning struck the Church of St. John the Baptist there on July 31, 1864, killing one parishioner, a young woman who left behind a family. The distraught widower asked the sisters to care for his children. This unexpected work soon expanded, and the sisters began to take in orphans, as well as boarding school students, and candidates to the community. The sisters soon bought a larger house and established
St. Francis Academy. During the summer of 1865, the
Guardian of the Franciscan friars in the United States,
Pamfilo da Magliano, summoned Moes to St. Bonaventure Friary, in
Allegany County, New York, along with the first
postulant to the community, Mary Ann Rosenberger. There he named Moes as
Superior General of the new congregation of the "Sisters of St. Francis of Mary Immaculate". At that time he bestowed the Franciscan
habit on Rosenberger, who took the name Sister Angela. Until 1880, the order used the constitution drafted for the
Franciscan Sisters of Allegany, a congregation da Magliano had previously established. By 1869, the sisters had built a new St. Francis Academy, teaching girls aged 3–20 and drawing students from across the nation.
Pastors around the whole country sought the Sisters to come to their parishes to teach their children, especially in non-English-speaking populations. By 1874, the sisters were teaching throughout five states, as far away as
Tennessee. ==Minnesota==
