Elkhart takes its name from Elkhart (or "Elk Heart") Grove, which along with Buffalo Hart was an area of woodland along the Edwards Trace. The grove's name has been attributed to its shape, resembling the heart of a elk. Prior to the forced expulsion of indigenous peoples from Illinois, a Kickapoo village was located at the grove. The history of non-indigenous settlement at Elkhart dates from the arrival of James Latham and his family at Elkhart Grove in the spring of 1819. James Latham's house, and later his son Richard Latham's place on the brow of the hill further south, were stops on the early stage routes from Springfield to Bloomington. Around 1822, James and Richard Latham built a horse mill at the foot of Elkhart Hill. Before this, the early settlers had been compelled to go to Edwardsville to mill. During the mill's existence, settlers came a great distance to get their grinding done and frequently camped overnight waiting their turn.
