Appalachian Community Histories – Treadway, Hancock County: The Post Office, the Mountain Roads, and the Flat Gap Zinc Mine
Treadway sits in Hancock County, Tennessee, in the country between Sneedville and the Hawkins County line. It is not the kind of place that left behind city council minutes, incorporation papers, or a thick municipal archive. It was a rural community, known through maps, post office records, family histories, cemeteries, court records, newspapers, and the memory of people who lived around the roads and ridges.
The federal place-name trail puts Treadway on the Lee Valley USGS topographic map at about 36.4187013 north latitude and 83.2243395 west longitude, with an elevation near 1,594 feet. The same mapping trail places it among the named communities of Hancock County rather than among incorporated towns. That matters because Treadway’s history has to be reconstructed from the records that touched it from the outside. The map named it. The post office served it. The roads crossed it. The mine changed it. Families carried its name in birth records, veteran schedules, obituaries, and cemetery stones.
Hancock County and the Road to Treadway
Hancock County itself was formed in 1844 from parts of Hawkins and Claiborne counties, with Sneedville as the county seat. That origin matters for Treadway because older families, land claims, church ties, and postal references may appear under Hawkins, Claiborne, or Hancock depending on the date and the record set being searched. TNGenWeb also notes that Hancock is a burned county, meaning early county records are thin and surviving court, deed, and census materials become especially important for reconstructing local history.
Treadway’s road identity is clearer in modern transportation records. The Tennessee Department of Transportation describes State Route 31 as a rural minor arterial highway between Mooresburg in Hawkins County and Treadway in Hancock County, connecting at its southern end to State Route 1, also known as U.S. 11W or Lee Highway. That official description makes Treadway more than a dot on a map. It marks the community as a mountain road connection between the Mooresburg side of Hawkins County and the Hancock County communities north toward Sneedville.
The Post Office Trail
For many Appalachian communities, the post office was the public sign that a settlement had become a recognized place. Treadway fits that pattern. One post office list records Treadway in Hawkins County from 1880 to 1897 and Treadway in Hancock County in 1897, a clue that should be checked against the original National Archives postmaster appointment records. The entry does not tell the whole story by itself, but it points researchers toward the federal postal books that can show dates, names, and administrative changes.
A stronger local clue appears in Goodspeed’s biographical history of Hancock County. In its sketch of W. T. Wolfe, Goodspeed says that Wolfe became a merchant in 1882 and was made postmaster at Treadway. That one sentence places Treadway inside the working world of country stores, mail service, and local exchange. In a rural community, the merchant and the postmaster often stood at the center of daily communication. Letters, newspapers, accounts, and news moved through the same small place.
The Tennessee Encyclopedia notes that Hancock County once had at least fifty-seven post offices, though most mail is now delivered through Sneedville. That broader county pattern helps explain Treadway. It was part of a postal landscape built for scattered ridges, valleys, farms, and small settlements, before modern roads and centralized delivery pulled many of those names out of daily use.
Families, Farms, and the Local Record
Treadway’s nineteenth and early twentieth century history is best read through family records rather than town records. The names tied to the community appear in census schedules, deeds, court cases, probate files, cemetery inscriptions, post office records, and newspaper notices. Because Hancock County has gaps in early courthouse records, those scattered sources matter even more.
The TNGenWeb Hancock County page points researchers toward deed indexes beginning in 1879, chancery court minutes beginning in 1870, surviving scattered chancery cases, census material from 1850 to 1930, old court case indexes, cemetery listings, obituaries, and the 1890 Union veterans schedule. These are not just genealogy tools. For a place like Treadway, they are the community archive. They show who owned land, who went to court, who served in war, who died, who married, who moved, and which post office connected them to the wider world.
The Civil War record is especially important in Hancock County. The 1890 special census of Union veterans and widows survives as a major substitute record for many families, since most of the regular 1890 federal census was lost. Hancock County indexes and transcriptions point to veterans and widows whose post office addresses help identify the neighborhoods where they lived after the war. Treadway appears in that kind of record trail, not as a battlefield, but as a place where Civil War memory settled into household life.
The Zinc Under the Ridge
The best-known industrial chapter in Treadway’s history came in the twentieth century with zinc. The Tennessee Encyclopedia states that zinc was discovered at Treadway in the 1950s, that mining continued until 1971, and that the mine employed more than 220 men at its peak. For a small Hancock County community, that was a major change. Treadway was no longer only a postal and road name. It became tied to one of the most important mineral stories in East Tennessee.
The Flat Gap Mine is the key name in that story. Mindat identifies the Flat Gap Mine in the Flat Gap and Treadway area of the Copper Ridge Mining District in Hancock County, locating it about half a mile northwest of Treadway and identifying it as a zinc mine owned by the New Jersey Zinc Company. The mineral list associated with the locality includes sphalerite, the chief ore mineral of zinc, along with galena, pyrite, calcite, dolomite, gypsum, anhydrite, and baryte.
Geologists treated the Flat Gap Mine as more than a local curiosity. W. T. Hill, R. G. Morris, and C. G. Hagegeorge published “Ore Controls and Related Sedimentary Features at the Flat Gap Mine, Treadway, Tennessee” in Economic Geology in 1971. That article places Treadway in a technical literature about East Tennessee’s Ordovician carbonate rocks, breccia bodies, and zinc deposits. For most local histories, geology is background. At Treadway, geology became employment, newspaper news, company records, federal mineral interest, and family memory.
A Community Changed by Work
The zinc mine gave Treadway a second identity. Earlier records show a rural place of roads, farms, stores, churches, post offices, and family networks. The mine added wage work, industrial traffic, outside corporate ownership, and a connection to national mineral markets. The New Jersey Zinc Company’s presence meant that a small Hancock County community became part of a much larger Appalachian zinc belt.
That change did not erase the older Treadway. It sat on top of it. The same community that appeared in post office records and Goodspeed biographies later appeared in mineral reports and mine references. The road that served farmers and families also served the movement of workers, equipment, and ore. The name Treadway survived because it belonged to more than one kind of record.
How Treadway Can Be Researched Today
The strongest research trail for Treadway begins with maps and post offices. The USGS and GNIS place-name record fixes the name and location. The Lee Valley topographic quadrangle shows the physical setting. TDOT highway maps and project records help explain the road network. The postmaster appointment records at the National Archives can confirm the federal postal timeline.
After that, the search moves into county and family records. Hancock County deeds, court minutes, probate files, tax records, cemeteries, census schedules, and newspapers are where the lives of Treadway residents appear. Local histories such as Hancock County, Tennessee and Its People and the Hancock County pictorial history may add family sketches, photographs, church references, and community memories that do not appear in official records.
For the mining period, the best sources are different. New Jersey Zinc Company annual reports, Tennessee Geological Survey publications, USGS mineral reports, Economic Geology articles, and Hancock County newspaper clippings can help reconstruct the Flat Gap Mine story. Together, those sources show how a rural community became tied to one of Hancock County’s most important industrial episodes.
Treadway in the Appalachian Record
Treadway’s history is not the history of a courthouse town or a boom city. It is the history of a named place that stayed alive through use. People said Treadway when they meant a road crossing, a post office, a store, a family home, a cemetery, a mine, or a place on the way to somewhere else.
That is why communities like Treadway matter. They remind us that Appalachian history is often kept in fragments. A line on a topographic map. A postmaster named in an old biography. A veteran’s post office address. A deed book. A cemetery. A newspaper clipping. A zinc mine reference in a geology journal. Put together, those fragments show a Hancock County community shaped by land, roads, mail, family, and work beneath Copper Ridge.

Author Note: Treadway is one of those Appalachian communities whose story has to be pieced together through maps, post office records, cemeteries, newspapers, and family traces. I like articles like this because they show how a small place can still leave a deep record when you know where to look.
