What stands out about Erwin’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The town of Erwin received its name by a mail mishap. On December 5, 1879, the name of the town was Ervin, in honor of D.J.N. Ervin, who had donated 15 acres (61,000 m2) of land for the county seat. A typo made by post office officials caused the name to be recorded as Erwin. The mistake was never corrected.
From 1890 to 2015 railroad operations contributed greatly to Erwin's economic and cultural identity.
The Charleston, Cincinnati and Chicago Railroad (the Triple C) was chartered in 1886 with its headquarters in Johnson City, Tennessee. Trains ran through Erwin in 1890, but by the end of the year, the company disbanded and all construction and operation ceased.
The Erwin post office opened in 1879, the earliest record of the town by name (U.S. post office records).
