Several Methodist ministers were active in missionary work in the "Soo" area in the 1830s. John Sunday, an Indian preacher from Canada, began missionary work in the Indian settlement at the Sault Ste. Marie Rapids around 1831. The Reverend John Clark followed in his steps two years later. Then in 1833, Peter Marksman, son of an Indian medicine man, was converted to Christianity and later became an esteemed minister of the Detroit Annual Conference. By 1834, the school had thirty-five students, and three "Methodist classes" were organized with forty Indians and nineteen whites. The Michigan Conference sent William H. Brockway to the mission as superintendent in 1839. He remained for ten years, serving most of that time as chaplain for Old Fort Brady.
