  ## Background

During this period, the sisters were active in the Dakotas, Nebraska, and Colorado. In 1886 they went to Dakota Territory to begin mission work to the Lakota in what would later become South Dakota. They turned their attention to children, coming to O'Neill in 1900. In 1908 they were invited to teach at St. Agnes Academy in Alliance, Nebraska.
