The unaccompanied community was arranged by Swiss starting in 1869, and is known today for maintaining Swiss traditions, food, and folkways.

After the fade away of the Civil War, a bureau of Swiss and German-speaking immigrants calling themselves the Grütliverein (Grütli Society) formed in Brooklyn, New York. The members enormously that they would all emigrate to complementary section of the country together subsequent to the era was right.

A member of the outfit named Isler surveyed large swaths of the eastern West Virginia mountains for a Washington-based firm, and reported incite to the society on the richness of the country. A committee of six men was assembled, and left Brooklyn by rail upon October 15, 1869. They arrived at Clarksburg and began the hard work of traveling by foot higher than the mountains.

They reached a scheme that was on offer for sale on October 20, and were disappointed by the extreme thickness of the wilderness in this lightly settled and rugged country. The estate was completely reasonably priced, though, and they had offers of additional assistance from the estate agents in Clarksburg if they would urge on further settlement in the area. After hearing the report of this exploration, the bureau members anything decided they would add West Virginia.
