Butler County, Ohio, a county in the extreme southwestern corner of the state, with Hamilton as the county seat. In this county was founded in 1819 the first of the Alsatian and South German Amish settlements in North America, of the Amish migration to America following the European Napoleonic wars. Butler County became a brief stopping place for many of the Amish immigrants later moving on to Illinois and Iowa. Among later Amish leaders who tarried here for a while were Christian Ropp, Peter Naffziger, Joseph Stuckey, all later of Illinois; and Joseph Goldschmidt of Iowa. The present congregation, with a meetinghouse in the village of Trenton, is now called the Trenton Mennonite Church and is a member of Mennonite Church USA.
