High hills, a deep valley, a broad river, and rocky falls shaped a place known in 1650 as Nawcatock, an Indian village whose name survives in the river today. In 1678 it was called Amaugsuck, the fishing place where the waters pour down. From 1738 it was known as Chusetown, after Chief Chuse, a scout in the French and Indian War. In 1803 General David Humphreys, friend and aide to General Washington, purchased Rimmon Falls and land with a mill and shop. In 1805 the community became Humphreysville in his honor, and in 1806 General Humphreys built near the falls one of the first large woolen mills to be successfully operated in the United States. In 1850 the town took the name Seymour after the state governor and held its first town meeting. The mills have long since vanished, but the falls remain as a reminder of its proud past.
