Mary T. (Mary Theresa) Longley

Mary Theresa Shelhamer Longley was an American Spiritualist author associated with the National Spiritualist Association. Available sources identify her as an officer in that organization, and her books show her writing under the name Mary T. Longley or Mary Theresa Shelhamer Longley.

She is linked to works such as Teachings and Illustrations as They Emanate from the Spirit World, Life and Labor in the Spirit World, and Outside the Gates, and Other Tales and Sketches. These titles suggest the range of her writing: part religious or philosophical discussion, part imaginative literature shaped by Spiritualist ideas about death, the soul, and communication with the spirit world.

The biographical details available online are somewhat inconsistent, especially around her birth year. One source gives May 6, 1863, while another text connected with her published work gives May 6, 1853. What does come through clearly is that she was active in American Spiritualist circles for many years and died in 1928.
