By 1850, the area had largely changed its ethnic composition, as many German farmers from Saxony had arrived during the 1840s. John Klehm might serve as an example; he was at first a potato farmer, supplying the Chicago market, and in 1856 began a nursery for cherry, apple, and pear trees, later moving into spruce, maple, and elm, and then flowers. By the late 1850s the area had become noted for its truck farms, sending dairy products as well as vegetables to Chicago on the railroad.
