Scope and arrangement
The bulk of Soule's papers consist of her letters to Rev. Henry Williamson, the Universalist pastor of the Dundee Unitarian Christian Church, Dundee, Scotland, dating from 1875, the year of her first trip to Scotland until her death in 1903. The letters mainly concern her missionary work and preaching in Scotland, in the town of Dunfermline, and in Glasgow. They also cover intervals spent in the United States (1876-1877 and 1882-1886) at her home in Fordham [Bronx], New York City, and preaching in New Jersey and in the West and Midwest. Soule mentions delivering a lecture on higher education for women in Missouri (September 24, 1877 letter). News of health, children, and other personal matters is also included. Soule attended several farewell parties in Philadelphia for Susan B. Anthony, who was about to sail for England, and her descriptions of these (February 22, 1883) are noteworthy.
The rest of the papers consists of: clippings of obituaries and other manuscript and printed material about her life; announcements and programs, 1875-1890, for services and other events at which Soule or Williamson led; a printed copy of a sermon "A royal woman" delivered by Soule on November 16, 1890 in Dundee; and letters to Rev. Williamson from correspondents other than Soule, 1878-1916.
