Harriet S. (Harriet Sophia) Caswell

Harriet Sophia Caswell (1834–1910) was an American author and missionary. Public-domain library records and book catalogs connect her with several books, including Stories and Sketches (1872), Walter Harland; or, Memories of the Past (1874), The Path of Duty, and Other Stories, and Our Life Among the Iroquois Indians (1892).

Her writing seems to move between fiction and religious history. The novels and story collections suggest a strong interest in duty, family, and moral choice, while Our Life Among the Iroquois Indians focuses on missionary work among the Seneca and Cayuga and on the lives of Asher and Laura Wright. That mix gives her work both a storytelling voice and a documentary value.

Some biographical details are harder to confirm cleanly from widely available sources, but authority records and memorial listings indicate that she was also known as Harriet Sophia Clark Caswell and later Harriet Sophia Caswell Broad. I couldn't confirm a reliable portrait image from the sources I found, so no profile image is included.
