There are 4 groups of Old Order Mennonites or Horse and Buggy Mennonites that live in Lancaster County, Pennsylvania. They are the Groffdale, Stauffer, Reidnebach, and Noah Hoover Groups. (Since this video was created the members of the Noah Hoover group have started to move away to another settlement. They weren't able to establish a settlement in the area) They are nicknamed the Wenger, Pike, and the 35ers respectively. The Noah Hoover group hasn't a nickname. Among these major groups there are split off groups that would be classified as the main group. They live an Old Order life much as the Amish in Lancaster County do. The video will further explain the differences and similarities.
