Oak Knoll was founded in 1924 and is one of nine schools in the Holy Child Network of Schools that provides independent Catholic education across the United States. The Sisters of the Holy Child Jesus have also founded schools in England, Ireland, France, Nigeria, and Ghana. All Holy Child schools operate under the Society of the Holy Child Jesus, based in Drexel Hill, Pennsylvania. Oak Knoll shares the goals of the Schools of the Holy Child Jesus. History Founded in 1924, Oak Knoll's roots go back to 1846, when Cornelia Connelly founded the Society of the Holy Child Jesus and opened her first school in England. The Provincial Council of the Society of the Holy Jesus responded to a need identified by the Bishop of Newark for a Catholic School for girls. In January 1924, the Society received permission from Rome to open a school in Summit, New Jersey. Several properties were considered, and the estate of William Zebdee Larned was acquired in May 1924. The site included the stone manor house, "Stoneover" (now known as "Grace Hall"), built in 1887. A stable, located where Connelly Hall now stands, provided gym and classroom space for the Junior School. Two houses on Prospect Street also contained classrooms and convent space. In 1954, Bonaventura Hall, named after benefactor Bonaventura (Kirby) Devine and her husband Christopher J. Devine a Wall Street banker, was constructed for the elementary grades, and in 1956, construction on the new Upper School, Connelly Hall, was completed.
