===Early communities===
Blackhawk village was a small community on the South Beaver Township line. Its first post office was established sometime after 1837. Even earlier, the New Salem United Presbyterian Church was established circa 1798, around the same time as Big Beaver's Mount Pleasant Church.<ref name="Ohioville"/>

In 1811, Four Mile United Presbyterian Church was founded. Located on Tuscarawas Road (whose name derives from the old [[Tuscarora people|Tuscarora]] hunting trail), the church was originally named Four Mile Square Church.

In 1816, Ohio Township lost some of its territory to Brighton Township. With the establishment of Glasgow borough (1854), Industry Township (1856), and Midland borough (1906), even more land was lost.<ref name="Ohioville"/>
