The
Swartzendruber Amish are the result of a division that occurred in Holmes County in the middle of the 20th century. The Swartzendruber Amish are noted for their use of reflective tape in place of bright triangular slow moving signs for road travel, as well as their avoidance of indoor plumbing. Swartzendruber Amish speak
Pennsylvania German, and are considered a subgroup of the Old Order
Amish, although they do not fellowship nor intermarry with more liberal Old Order Amish.
