In 1825 several Swiss, who had joined Lord Selkirk's Red River colony in Canada in 1821, settled at Gratiot's Grove northeast of Galena, Illinois. In 1845 New Glarus was founded in southern Wisconsin's Green County, today the best known settlement of Swiss origin. Numerous Swiss also settled in the towns of Monroe, Washington, and Mount Pleasant. In 1848 Bernese Swiss established Alma on the Mississippi, which counted some 900 Swiss in 1870. A French Swiss group connected with the Protestant Plymouth Brethren established a community in Knoxville, Tennessee, in the same year.
June 15, 1904 marks a dark day: 1,300 tourists boarded the General Slocum steamboat for a daytrip along the East River. Many of them were women and children from the German-American community in Kleindeutschland (Little Germany) in New York City's Lower East Side. The ship sank after a fire broke out, and more than 1,000 people drowned. Residents of "Little Germany" were devastated. The Lower East Side of Manhattan had been a haven for German immigrants since the 1840's, but many couldn't bear the pain. So they relocated to Yorkville on the Upper East Side.
