B+
HistoryA character grade: shown, never part of Cowan’s overall grade.
Tennessee towns list more on the Register than most of the country (a typical Tennessee town has 6.1 per 10,000 residents, the U.S. 2.4), so Cowan’s 5.2 sits near the middle of its state (49% of Tennessee towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
NoteThe founding year comes from Wikidata alone; no second source gives 1808.
How sure. Graded on any two of the three inputs instead, the letter would range from B to B+. The pre-1940 share is a Census survey estimate (±5.3 points).

Timeline
Cowan, 1808 to 1997
Woven from the archive, old maps, post office records, the National Register and the people born here.
The earliest settlers arrived in the Cowan area in the late 18th and early 19th centuries. The home of one such settler, William Russell, served as the Franklin County Courthouse until the establishment of Winchester in 1810.
The town of Cowan dates from the mid-19th century and developed mostly as a railroad town. It was the site where several branch lines met the main Nashville to Chattanooga trunk of the Nashville, Chattanooga and St. Louis Railway which ran through the important Cowan Tunnel. As the last stop before the uphill climb onto the nearby Cumberland Plateau, pusher engines to assist trains in making the steep ascent were based there, and are still in use today.
In 1808, according to Wikidata. Cowan’s post office opened in 1854, and the census of 1880 counted 222 people here.
