This fonds consists of letters written to Cornelius L. Plett by friends and family. They provide a valuable insight into the daily life in Mennonite village settlements in Canada, U.S., and Mexico in the first two decades of the twentieth century, as they discuss village and church dynamics, as well as personal issues and challenges of the writers. Most of these letters are written in the German Ghotic Script.
