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 Henrietta’s 1.9 sits below most of its state (24% of New York towns have fewer) while its 9 historic buildings outnumber those of 75% of U.S. towns.

The first residents of present-day were Native Americans. Although no evidence of Native American villages has been found in Henrietta, numerous artifacts and skeletons have been unearthed by farmers and archeologists over the past 200 years. With the end of the American Revolution, several Iroquois tribes that had sided with the British were forced to leave Upstate New York. As a result, land became available for European settlers in the Finger Lakes and Genesee Valley regions.
