HistoryA character grade: shown, never part of Greenville’s overall grade.
Maine towns list more on the Register than most of the country (a typical Maine town has 15.9 per 10,000 residents, the U.S. 2.4), so Greenville’s 14.8 sits near the middle of its state (51% of Maine towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±5.3 points).

What stands out about Greenville’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
First called T9 R10 NWP (or Township 9, Range 10, North of the Waldo Patent), the land was granted about 1812 by the Massachusetts General Court to Thornton Academy in Saco. In 1824, Nathaniel Haskell of Westbrook bought the Thornton Academy Grant. With Oliver Young and John Smith, he began clearing trees that summer for farming near Wilson Pond, where the Wilson Stream would provide water power for mills.
