More historic than 48% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Green Township is more historic than 48% of U.S. towns, #677 of 993 in Ohio. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
Ohio towns list about as much on the Register as the country (a typical Ohio town has 2.9 per 10,000 residents, the U.S. 2.4), so Green Township’s 2.8 sits near the middle of its state (55% of Ohio towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

Passages that mention Green Township, cut from the printed page as they were published.
The lands of Green Township were level and swampy and uninvitiug to the early emigrants seeking homes in the North and West, and, in consequence, permanent settlements were not made, comparatively speaking, until a late day. There were probably no residents at all of the country now comprising the territory of Green prior to 1810, or even as late as the war of 1812. If so.
