St Mary's of Rosemount, as the church was called, also had a two-story framed schoolhouse and convent. From 1904-1907 lay teachers from the church taught their students. These lay teachers included: Peter Flax, Mary Mettle, Josephine Brink, Miss Levelholtz, and Julia Post.
From 1908 - 1966 Sisters of the order of St Francis came to teach and inspire the young minds of the school. Listed below are the names of those dedicated Sisters, their former names, occupations at the school, and years at Rosemount. This information was found at the Warren County Historical Society.
