 Edward Marsden, defected to Presbyterianism, the dominant faith of the surrounding Tlingit communities.Marsden even assisted in the establishment of a rival, Presbyterian Tsimshian community at nearby Port Gravina (1892–1904) and, later, campaigned tirelessly and with some success for the Bureau of Indian Affairs to oust Duncan from his position, partly on grounds that Duncan had too much authority in the community and opposed any Native self-betterment through education and individual economic self-sufficiency if it put parishioners out of his personal control.In 1914–1915, the Interior Department seized many of the Mission buildings and built a modern school at Metlakatla.
