The Story
The first-story east wing of this house, built around 1810 by Jack Thomas — Grayson County's first county and circuit court clerk — was the earliest brick residence in the county. Thomas added a two-story Federal-style brick wing to the north, and though alterations in the 1870s and 1880s reshaped the house, its original walls survive along with uniform log joists supporting the first floor.
Why it matters
As the county's first brick home, it marks the moment a raw frontier settlement began building the permanent, refined architecture of a settled community.
The story behind this marker
AI contextThe era
Grayson County lies in the rolling country of central Kentucky, and in the first decade of the 1800s it was still very much a frontier settlement finding its feet. The Early Republic was a time when such places were making a crucial transition — from the temporary, hand-hewn world of the first arrivals to the permanent, ordered life of an established community.
You can read that transition in building materials as clearly as in any document. The earliest frontier homes were log, thrown up quickly from what the forest offered. Brick was something else entirely: it required kilns, skilled labor, and a settled confidence that the community would endure. A brick house on the early frontier announced that a place meant to stay.
At the same time, the machinery of self-government was arriving. New counties needed clerks to keep their records, courts to settle disputes, and officials to give the community legal shape. A house built around 1810 by the county's first court clerk sits precisely at this meeting point — where the raw settlement was becoming an organized county.
People & events
The house was built around 1810 by Jack Thomas, who held the offices of Grayson County's first county and circuit court clerk. As clerk, he was one of the essential figures of a young county — the keeper of its official memory, the man whose ledgers recorded deeds, suits, and the ordinary business by which a frontier community governed itself.
The first-story east wing he built was the earliest brick residence in the entire county — a genuine first, and a statement of both his standing and his optimism about the settlement's future. He later added a two-story brick wing on the north in the Federal style, the restrained, symmetrical architecture fashionable in the young republic, giving the house a dignity to match its owner's civic role.
Time reshaped the house without erasing it. Alterations in the 1870s and 1880s changed its appearance, yet the original walls remained standing beneath the later work. One quiet detail preserves the builder's craft most vividly: the uniform log joists that support the first floor, a striking feature carrying the frontier's own timber right inside the county's first brick home.
Its place in the American story
The Jack Thomas House captures a moment repeated across the whole settling frontier: the instant a community stopped merely surviving and began building for permanence. The first brick house in a county is a milestone that meant something to the people who watched it go up — visible proof that theirs was no passing camp but a place with a future. That threshold, crossed county by county, is how the American interior became settled ground.
It matters, too, that this particular house belonged to the first court clerk. The spread of American settlement was not only a story of land and cabins but of institutions — courts, records, and law reaching into each new county. A house that joins the county's first brick construction to its first official recordkeeper ties together, under one roof, the physical and the civic sides of that founding.
And the survival of the original walls, and those uniform log joists, gives the building a rare documentary honesty. Later generations altered the house, as families always do, but they did not obliterate its beginnings. It remains a legible record of the exact years when a Kentucky frontier settlement was turning itself into a permanent community.
If you visit
Look at this house as an archaeologist would, in layers. The oldest part is the first-story east wing — the earliest brick residence in Grayson County — and around and above it are the later additions and the alterations of the 1870s and 1880s. Try to pick out where the earliest work ends and the later work begins; the house rewards a slow, attentive eye.
If you can learn anything about the structure, the detail to look for is the framing: uniform log joists supporting the first floor, the frontier's own timber tucked inside a brick house. It is a small thing, but it perfectly embodies the moment the marker commemorates — log-building craft carried straight into the county's first permanent home.
Leitchfield and Grayson County offer the pleasures of small-town Kentucky, and this house fits well into a road trip through the state's early settlement history. Stand before it and remember what the first brick in a frontier county once meant: a family, and a community, declaring plainly that they had come to stay.

Morgantown & Daniel Morgan
Morgantown, KY
Founded as Funkhouser Hill, this Butler County seat was renamed Morgan Town in December 1810 to honor Daniel Morgan, one of the American Revolution's most gifted battlefield tacticians. The settlement grew from a nucleus of Revolutionary War veterans granted land for their service, mingling with pioneers streaming westward across early Kentucky. Morgan himself, born around 1735, rose from a French and Indian War teamster to the general whose double-envelopment of Banastre Tarleton at Cowpens in 1781 earned him a gold medal from Congress.
Last Recorded Indian Raid
Hart County, KY
In October 1792 — the very year Kentucky entered the Union — a party of travelers was ambushed at Oven Spring, leaving several settlers dead or carried off and their pack horses seized. Such raids were the grim punctuation of a decades-long struggle over the Ohio Valley, where Native nations fought to hold ground against the flood of settlers pouring through the Cumberland Gap. This marker records what local memory held to be the last such attack in the county, closing the violent frontier chapter of the region's early history.
Barren County
Glasgow, KY
Formed in 1798 from Green and Warren counties, Barren County took its name from the open 'barrens,' or prairies, that drew early explorers and settlers. During the Civil War the area saw hard use: the first two of Morgan's Raids passed through in 1862, the same year General Braxton Bragg's Confederate army entered Kentucky here.
First Presbyterian Church of Glasgow
Glasgow, KY
This Barren County congregation formed around 1802, when member Isaac Robertson donated a lot for a log meeting house and the Reverend John Howe served as first minister. The present Gothic Revival sanctuary, built about 1853, features Tudor-arched windows and doors and brick pilasters, and the town's oldest cemetery lies behind it. The church has anchored the same site for more than two centuries.
