HistoryA character grade: shown, never part of Hermon’s overall grade.
New York towns list more on the Register than most of the country (a typical New York town has 12.3 per 10,000 residents, the U.S. 2.4), so Hermon’s 0.0 sits below most of its state (10% of New York towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A. The pre-1940 share is a Census survey estimate (±9.6 points). The founding year is the first post office, not a stated founding date.

What stands out about Hermon’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The town was established in 1830 as the "Town of Depeau" from the towns of De Kalb and Edwards. In 1834 the town's name was changed to Hermon, after a post office in the town, due to the presence of another location named after Francis Depeau. In 1852, Hermon reached its current size after a small part from its southeast corner was moved to the town of Edwards.
The community of Hermon was set off from the town in 1887 by being incorporated as a village, which was dissolved in 2016.
The Hermon post office opened in 1828, the earliest record of the town by name (U.S. post office records).
