Alma Slagel Eigsti "adopted" a Russian Mennonite refugee named Margareta Unruh through her Sunday school class at Waldo Mennonite Church in Illinois. Unruh and her family were forced to flee Russia in 1943, first staying in Holland and later immigrating to Paraguay. Eigsti and Unruh corresponded with each other from 1946-1981. In this collection are the letters that Eigsti received from Unruh. The letters describe Unruh's domestic life and her personal needs. There is also a small amount of correspondence from Tina Boschmann.

Most of the papers document his conscientious objector status at Camp Funston during World War I.

Also included is an 1874 Russian passport of his grandfather Daniel Krehbiel, and his own passport from a 1968 service trip to Paraguay.

The papers of Vernon and Evangeline Matthies Neuschwander primarily document relief and service work to Russian Mennonite refugees after World War II.  Materials include correspondence, poems, testimonies, and songs by Russian Mennonite refugees, reports and correspondence pertaining to Mennonite Central Committee relief work in the Netherlands and Paraguay, a diary kept by Evangeline Matthies Neuschwander during her Europen relief work, correspondence between Vernon and Evangeline Matthies Neuschwander, and a well-labeled photograph album documenting Evangeline Matthies Neuschwander's relief and service work.  Other materials include records of Vernon Neuschwander's Civilian Public Service work, family and genealogical materials, Evangeline's writing and reminiscences, and miscellaneous materials.
