Mennonites

Background
The Mennonite religion currently has about 1.5 million followers (2006). This anabaptist religion is named after Frisian Menno Simons, who was responsible for formalizing the teachings of other earlier Swiss founders. The Mennonites emigrated from Switzerland in several distinct groups, including those who went to Russia before coming to America and those who traveled down the Rhine to Holland, England, and then the United States.

Record Keeping
The Mennonites are deeply involved in keeping records of their ancestors and descendants. An extensive collection of genealogical materials is maintained by the Lancaster Mennonite Historical Society at its facility in Lancaster, Pennsylvania. They also issue a monthly publication, Pennsylvania Mennonite Heritage, which contains extensive articles about the early Mennonite ancestors and their religion.The maintains a complete collection as well as the indexes. The indexes also available as online PDF downloads.

Ancestry
The Mennonite ancestry is Celt, but these earlier peoples did not maintain a written language. The only records of them are those pieced together from the writings of their Roman conqueror, Julius Caesar and archeological findings. The earliest remains of any Celtic people are of those trapped in a salt mine near Zurich, Switzerland.
