Handwritten histories of Mennonite congregations in southwestern Pennsylvania, presumably used in the book Seventy-fifth Anniversary Observance of the Southwestern Pennsylvania Mennonite Conference, coauthored with John L. Horst. Other materials include scattered research correspondence and notes.
A transcribed, typewritten copy of a diary kept by Ammon Sala, a Mennonite conscientious objector who was conscripted for military service in World War I. Sala left for Camp Lee on October 4, 1917 and was not released until December 1918. Sala's diary entries are very brief, describing one or two daily activities.
The diary was transcribed by Mark Moyer. The original diary remains in the possession of Helen Lenda.
