HistoryA character grade: shown, never part of Jefferson Township’s overall grade.
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 Jefferson Township’s 12.2 sits above most of its state (77% of Ohio towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±8.6 points).

Jefferson was officially founded by Gideon Granger, U.S. Postmaster General during Thomas Jefferson's administration, in 1803. He envisioned the new settlement as a "Philadelphia of the West," and early plans for the village were based upon the layout of that city. A cabin was erected by Granger's agent in 1804, but the settlement's first permanent residents arrived only in 1805: the Samuel Wilson family. Wilson, misled by land agents, moved to Ohio in late autumn expecting to find a thriving city on Granger's land. Instead, he found a wilderness, broken only by trees emblazoned with Philadelphian street names, marking where future streets would be built. Wilson himself died after two weeks of herculean effort to prepare for the winter, but his family stayed on as the first citizens of Jefferson. In 1811, Jefferson was made the county seat of Ashtabula County.
