Decatur County library genealogy room preserves local history records
The Decatur County Library’s genealogy room puts courthouse-era records, microfilm, and family files within reach at 20 W. Market St. in Decaturville.
At 20 W. Market St. in Decaturville, the Decatur County Library’s Tennessee and Genealogy room gives residents a place to chase family lines, check old property questions, and pull together school or community history projects without leaving town. The room is one of the county’s most useful public records tools, tucked inside a building that has been part of local civic life for generations.
A county archive in plain sight
The library’s own history makes clear that this is more than a book-lending stop. Decatur County’s first library service began in October 1942 as a TVA-sponsored effort, and the original county library was first housed in the superintendent of education’s office in the courthouse. In 1993, the collection moved into a permanent 5,000-square-foot library on Court Square, giving the county a fixed home for research, reading, and public access.
The same place that now supports internet use, copying, faxing, and public research also preserves the paper trail of Decatur County’s towns, families, and courthouse era.
What the genealogy room holds
The biggest draw is the genealogy room itself. It has newspapers on microfilm from 1893 through 1996, along with marriage and birth records, census records, cemetery records, county history records, Civil War and Revolutionary War book records, county deeds and court minutes, and older courthouse records that include wills and birth certificates.
That mix makes the room useful for far more than tracing a surname. A family trying to confirm a burial site can start with cemetery records and death notices. A student working on a local history project can use the newspaper files and county history materials. Someone sorting out a land question can use deeds, court minutes, and courthouse records to trace how a parcel changed hands over time.
Researchers can also turn to the Decatur County Clerk’s Office for marriage and wills records, the Decatur County Registrar of Deeds for land records, the Decatur County Health Department for vital records, and National Archives resources for federal materials. Obituary and death-notice indexes add another path when a family name disappears from living memory but still appears in print.
How to begin a search
The simplest way to use the genealogy room is to start with one known detail and work outward. A full name, a rough date, a town, or a cemetery can be enough to break open a search.
1. Begin with the most recent clue you already have, such as a birth, marriage, or death date.
2. Check the newspaper microfilm, especially if the person lived between 1893 and 1996, when the library’s run is strongest.
3. Use marriage and birth records, then compare them with census records and cemetery records.
4. If land is part of the question, move to county deeds and court minutes, then cross-check with the registrar of deeds.
5. For older family lines, add courthouse records, wills, and birth certificates, then widen the search to county history records and obituary indexes.
Newspapers can confirm dates and place names. Census records can anchor families to a household and a community. Deeds and court minutes can show where a family lived and how land moved through generations.
Why the records are so valuable
The Tennessee State Library and Archives lists courthouse fires in 1869 and 1927.
The county was formed in 1845 from Perry County by dividing Perry County along the Tennessee River and adding a parcel from Henderson County, with the change taking effect March 1, 1846. The county was named for Commodore Stephen Decatur, the War of 1812 naval hero.
The county’s creation traces back to a petition led by Samuel Brasher. In 1845, 200 citizens from the west side of the river asked for a new county.
A guide to Decatur County’s wider local history
The library’s records make more sense when paired with the county’s geography and town history. Decatur County borders the Tennessee River in West Tennessee and sits within the larger Jackson Purchase region. Decaturville was established in 1847 and serves as the county seat. Parsons grew around railroad development, while Perryville’s history was reshaped by the Kentucky Lake and Gilbertsville Dam project.
A family history search often becomes a geography search, a courthouse search, and a migration search at the same time. One branch may have followed railroad work to Parsons, another may have stayed near river land, and another may have moved after the lake project changed Perryville’s footprint.
Residents of smaller communities such as Scotts Hill and Bath Springs also appear in the county’s records, even when the town names change or the physical landscape does. A deed, a birth record, or a newspaper notice can connect a modern Decatur County resident to a place that no longer looks the way it once did.
A resource for schoolwork, family work, and land questions
A student can use it for a local history assignment with real names, dates, and places instead of generic background. A family can build a reunion booklet from marriage records, cemetery records, and newspaper references. A property owner can use deeds and court minutes to understand why a tract of land carries an older boundary or a long chain of title.
The library also offers internet access, copying, faxing, and public research support, making it a one-stop starting point rather than a dead-end archive.
