There are several religious groups named Brethren that are not related to the Schwarzenau Brethren movement. The Moravian Brethren and Swiss Brethren are not related to the Schwarzenau Brethren. The Plymouth Brethren arose in England and Ireland early in the 19th century. The United Brethren originated in 18th-century Pennsylvania with William Otterbein and Martin Boehm. The River Brethren movement adopted the view of trine immersion and most other Anabaptist beliefs and practices from the Schwarzenau Brethren. Today, the Old Order River Brethren are very similar to the Old Brethren—both being part of the Anabaptist tradition. The Apostolic United Brethren is a group within the Latter Day Saint movement and is not related to the Schwarzenau Brethren.
