To collect, preserve, and make available for educational and historical purposes artifacts, documents, personal items, and any works or items directly relating to the history and life of Rose O'Neill. In addition BHS accumulates research materials that documents, authenticate, explain and provide detailed information about the character, personality and accomplishments of the talented and generous Rose O'Neill who with her family lived at the Bonniebrook Homestead from 1893-1947. In order to achieve that mission, BHS has built a replica of O'Neill's home for visitor tours. In addition, a BHS Visitor Center is constructed on the site. It includes a Fine Art Gallery, Research Library, Museum, Gift Shop, and Multi-purpose room. These faciilities require much repair and maintenance.
