Seymour was originally the site of Newell's Station, a frontier station established by early Sevier County pioneer Samuel Newell (1754–1841) in 1783. The first court of Sevier County,
State of Franklin, was held at Newell's Station in March 1785. During the 19th century, the community was known as Trundles Crossroads where the main road from
Sevierville forked, with one branch continuing northward to
Knoxville and one branch westward to
Maryville (now the intersection of Boyds Creek Highway and Old Sevierville Pike). After the completion of the
Knoxville, Sevierville and Eastern Railway on December 18, 1909, the community's station was named Seymour in honor of the line's chief engineer, Charles Seymour. The Trundles Crossroads Post Office changed its name soon afterwards to reflect the community's designation.
Unsuccessful attempts to incorporate On multiple occasions, residents have met to discuss the possibility of incorporating as a town or city. The majority of residents have opposed incorporation, arguing it would bring higher taxes and expanded government, while others say that the community would benefit from having a community center, along with sidewalks that might be constructed with the added revenue. Some Blount County residents want their portion of the 37865
zip code to be included within the proposed city limits; however the incorporation meeting was geared primarily toward the Sevier County portion of the community. In the end, the voters overwhelmingly voted to keep Seymour unincorporated. ==Geography==
