This collection consists of 50 letters written by members of the Peter Schroeder and Johann Fast families from 1930-1988. These are letters which the David and Agatha Fast family of Manitoba received from members of the family who were left behind in the Soviet Union when they emigrated in 1929-1930. Of the 50 letters, 42 were written between 1930-1934, and the remaining 8, scattered widely over the period from 1939-1988. They convey the experiences of the terrifying Stalinist years and convey glimpses into how life unfolded for the family.

This collection contains the correspondence collected by Anna Epp Ens in conjunction with a number of Epp family reunions and the publications associated with this family. In 1975 the descendants of Heinrich Epp (1811-1863) met at the International Peace Gardens and Camp Koinonia south of Boissevain, Manitoba. Out of this gathering grew the request that a book be compiled and published. Anna Epp Ens took up the task supported by a book committee, which led to the publication of the book "The House of Heinrich: The Story of Heinrich Epp..." The collection also includes the photographs that were collected (and published) as well as files related to publishing a newsletter and organizing subsequent reunions, and the update of data distributed on a CD ROM in Brother's Keeper Format in 2010.
