This series contains records concerning the involvement of the Sisters of St. Joseph in the London diocese in the field of education in St. Thomas, Ontario. While the records mention interactions with the Elgin County Roman Catholic Separate School Board and other schools in St. Thomas, the records in this series are all from or about St. Joseph’s High School. Material includes a feasibility study, yearbooks, news clippings, correspondence, photographs, pamphlets, and drama festival programs. The correspondence primarily concerns administration, funding, alumni events, and the Sisters who worked at the school. The major topics of the material are the Sisters’ employment, administrative concerns, the school’s drama department, and coordination of alumni events. There is also an annotated script for the play TUB by James W. Nichol, which the school performed in 1971.
