In 1836, six Sisters of St. Joseph left the motherhouse in France, bound for St. Louis via New Orleans. Based in Carondelet, the congregation soon spread throughout the United States, where they labored in schools, hospitals, and other apostolates. In 1860, a plan was formed to reorganize the widely dispersed sisters into a new congregation headquartered in the United States. Pope Pius IX gave final approbation on July 31, 1877.
