What drives Cornwall’s History grade
On its age, its old homes and the National Register, Cornwall is more historic than 93% of U.S. towns. All 3 inputs are above most U.S. towns; its age ranks highest and its National Register listings lowest.
A
HistoryA character grade: shown, never part of Cornwall’s overall grade.
Vermont towns list more on the Register than most of the country (a typical Vermont town has 147 per 10,000 residents, the U.S. 2.4), so Cornwall’s 91.1 sits near the middle of its state (55% of Vermont towns have fewer) while its 11 historic buildings outnumber those of 76% 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 (±10.9 points). Two sources give 1761.

After Daniel Foot discovered the defect in his title under the Weybridge charter, he purchased the right of pitching under the Cornwall charter and laid out one hundred acres, which included the whole of the falls on the Cornwall side and extended some forty rods south of them to " the old Weybridge corner."
