What drives Owasco’s History grade
On its age, its old homes and the National Register, Owasco is more historic than 86% of U.S. towns, #336 of 758 in New York. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its National Register listings lowest.

HistoryA character grade: shown, never part of Owasco’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 Owasco’s 17.1 sits near the middle of its state (54% of New York towns have fewer) while its 6 historic buildings outnumber those of 72% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to A. The pre-1940 share is a Census survey estimate (±6.2 points). The founding year is the first post office, not a stated founding date.

What stands out about Owasco’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In early times, Owasco was home to the Cayuga, who lived primarily between Owasco and Cayuga lakes, which lay between the territory of the Onondaga and Seneca. Jesuits founded missions among the Cayuga in the mid-17th century. In 1660, there were approximately 1,500 Cayuga.
The land was first settled by Europeans around 1792, by a man named Herman Mesgow.
After the American Revolution, most Cayuga relocated to Canada after the Treaty of Canandaigua in 1794, although some bands were allowed small reservations in New York. New York made separate purchases and leases of land from the Indians, which were not ratified by the US Congress.
The town of Owasco was formed in 1802 from the town of Aurelius.
