The story
How Eaton Rapids Township came to be
From Wikipedia’s history of Eaton Rapids Township.
The Potawatomi people established a village in the area of what is now Eaton Rapids in about 1774. This was part of their wide territory in historic times.
The area constituting Eaton Rapids was first settled by Euro-Americans around the year 1835, who were drawn there because of the timber and water power in the area. It became a center of industry. The following year, a sawmill was constructed near Spring Brook in Spicerville; it provided the lumber settlers used to build Eaton Rapids. In 1837, the Old Red Mill was constructed by the mill company; it used waterpower from the stream to grind corn. The mill company later used wood from Spicerville to construct their own sawmill along the Grand River, as well as a wool carding mill.
In 1835, according to Wikidata. Eaton Rapids Township’s post office opened in 1882, and the census of 1860 counted 581 people here.
