What drives Oak Hill’s History grade

A−
HistoryA character grade: shown, never part of Oak Hill’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 Oak Hill’s 6.5 sits above most of its state (68% of Ohio towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B+ to A−. The pre-1940 share is a Census survey estimate (±8.1 points). The founding year is the first post office, not a stated founding date.

What stands out about Oak Hill’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The Village of Oak Hill was officially formed on January 12, 1873, from portions of Jefferson and Madison Townships.
Many immigrants from Cardiganshire, Wales, had previously settled in the area, with the first arriving in the Gallia/ Jackson County area in 1818 and many more in the late 1830s and 1840s- an era referred to as "The Great Welsh Tide". Several Welsh churches were constructed in the Oak Hill Area in the 19th Century, with some of them conducting services in the Welsh Language in to the 1920s. The Welsh-American Heritage Museum is located in the former Welsh Congregational Church on East Main St in the village.
