A−
HistoryA character grade: shown, never part of Trion’s overall grade.
Georgia towns list more on the Register than most of the country (a typical Georgia town has 10.0 per 10,000 residents, the U.S. 2.4), so Trion’s 24.6 sits near the middle of its state (62% of Georgia towns have fewer) while its 5 historic buildings outnumber those of 70% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A. The pre-1940 share is a Census survey estimate (±7.7 points).

What stands out about Trion’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Trion had its start in the 1840s when the Trion Mills cotton mill was established there. A post office called Trion Factory opened in 1847, and in 1904 the name was changed to Trion. The name "Trion" was chosen by the mill's three founders (Andrew Allgood, Spencer Marsh, and W.K. Briers) as a way to commemorate their partnership. The Georgia General Assembly incorporated Trion as a town in 1862.
Though the mill burned in 1875, it was eventually rebuilt, and evolved into what is now the Mount Vernon Mill No. 3.
