The Swiss Amish (Pennsylvania German: Schweizer-Amisch) are a subgroup of the Amish that emigrated to the United States mostly in the middle of the 19th century directly from Switzerland and Alsace, after the 18th-century emigration of most Amish via the Palatinate. They do not speak Pennsylvania German, but either a form of Bernese German or a Low Alemannic Alsatian dialect. Their main settlements are in Adams County, Indiana (Bernese Amish) and in Allen County, Indiana (Alsatian Amish). They form two distinct Amish affiliations.
Amish coming directly from Switzerland, neighboring Alsace and the Montbéliard region first came to the Midwest in the 1830s. Amish from Bern and the Jura Mountains settled in Wayne County, Ohio, in 1835. In 1840 they went west and founded the settlement in Adams County, Indiana. In 1850 Amish from the Montbéliard region settled in Stark County, Ohio, and founded the settlement in Allen County, Indiana, in 1852. Not all Swiss Amish migrations can be traced. The Amish settlement in Daviess County, Indiana, founded in 1868, was settled largely by Swiss Amish from Allen County, but later was mostly assimilated into the Pennsylvania German Amish culture. There are still speakers of the Alsatian dialect in Daviess County, however.
The Swiss Amish are more conservative concerning the use of technology than the majority of the Amish. Characteristic for the Swiss Amish is the use of open buggies only and the marking of graves with plain wooden stakes bearing only the initials of the deceased.
Most speakers of the Alsatian dialect also speak or at least understand Pennsylvania German.
The Swiss Amish of Adams County and to a lesser extent the ones of Allen County maintain the practice of yodeling from their Swiss homeland. According to Chad Thompson almost every Amish of Adams County can yodel. Yodeling is an important symbol of their particular Swiss Amish identity. Examples of Swiss Amish yodeling can be heard online.
There are certain last names which are very common among the Swiss Amish and which are not found often elsewhere. These names include: Schwartz, Hilty, Lengacher, Graber, Wittmer, Shetler, Christner, Eicher, Girod, Wengerd and Wickey.
The estimated population of the Swiss Amish was 1,900 in 1960 and 21,195 in 2015.
As of 2011 the two affiliations of the Swiss Amish had together 152 of the 1,913 Amish church districts, accounting for about seven to eight percent of all Amish. Most Swiss Amish are located in Indiana, but there are Swiss Amish settlements in other states, most notably in Michigan, New York, Missouri and Ohio.
The largest Swiss Amish settlement is located in Adams County, Indiana, near Berne with a total Amish population of 8,595 people in 2017. The second largest Swiss Amish settlement is located in Daviess County, Indiana with a total Amish population of 4,855 people in 2017.
