Buckner Cemetery
McKinney, Collin County, Texas
Marker Inscription
The land surrounding this historic cemetery was part of a grant obtained by John McGarrah, a member of the Peters Colony who arrived in this area in 1843. McGarrah founded a trading post near this site, and soon the Fort Buckner settlement was established. It would later become the first county seat of Collin County. David William O'Brien (1808-1885) came to Collin County with his family in 1857. He eventually acquired the part of the McGarrah land which included this site. The Buckner Cemetery, which was established on the O'Brien land, has also been referred to as O'Brien Cemetery over the years. Although there may be earlier unmarked graves, the oldest documented burial is that of Franklin O'Brien (1851-1870). Many early pioneers of Collin County are interred here, including victims of a smallpox epidemic in the 1870s. According to local tradition, a Kiowa Indian named Spotted Tail also lies here in an unmarked grave. The only physical remnant of the Buckner community, this cemetery serves as a reminder of the early history of Collin County. (1988) [Historic Texas Cemetery medallion added 2001]

The Story
When John McGarrah arrived with the Peters Colony in 1843 and set up a trading post, the Fort Buckner settlement grew around it and briefly served as Collin County's first seat. This burial ground on land later owned by the O'Brien family holds many of the county's earliest pioneers, including victims of a smallpox epidemic that swept through in the 1870s, and by local tradition a Kiowa man remembered as Spotted Tail. It is the last physical trace of a frontier community that has otherwise vanished into the North Texas prairie.
Why it matters
Pioneer cemeteries like this one preserve the human record of frontier settlement long after the towns themselves disappear, anchoring a county's origins to a specific patch of ground.
The story behind this marker
AI contextThe era
When John McGarrah reached this part of North Texas in 1843, Texas was not yet part of the United States. It was an independent republic, short of money and eager for settlers, and it handed out large tracts of frontier land to colonizing companies that promised to fill them with farm families. The Peters Colony was one of these ventures. Its grant covered a broad sweep of the rolling blackland prairie and timbered creek bottoms in what is now the Dallas–Fort Worth region, and it drew settlers mostly from the upper South and Midwest. They came for free land and stayed to build the first communities of the region.
Those early years were raw. Settlements were small clusters of cabins strung along creeks, trading posts were lifelines, and the line between settler country and the hunting grounds of Native nations was still shifting. A trading post like McGarrah's was more than a store. It was where news, supplies, and neighbors came together, and that is why settlements so often grew up around one.
Texas joined the Union in 1845, and new counties were carved out of the frontier soon after. Collin County was one of them. For a short time the Fort Buckner settlement served as its seat of government. But county seats in that era were often moved to a more central or more promising site, and Buckner lost the honor. The community slowly faded, as many early Texas settlements did when the courthouse, and later the railroads, went elsewhere.
By the time David William O'Brien brought his family to the county in 1857, the frontier was filling in quickly. Later decades brought Civil War, Reconstruction, and the outbreaks of disease that could tear through rural communities with frightening speed. All of that history is layered into this small burial ground.
People & events
The story starts with John McGarrah, one of the Peters Colony settlers who took up land here in 1843. He did more than farm it. He opened a trading post, and the little settlement that grew around it took the name Fort Buckner. For a brief, important moment that settlement was the center of a brand-new county, the place where Collin County's public life began.
The next chapter belongs to the O'Brien family. David William O'Brien, born in 1808, arrived with his family in 1857 and in time acquired the part of McGarrah's old land that holds this cemetery. That is why the burial ground has carried two names over the years, Buckner and O'Brien. The double name keeps both the vanished settlement and the family who cared for the ground in view.
The oldest burial we can document is Franklin O'Brien's. He lived from 1851 to 1870, so he died at about nineteen. The marker is honest that there may be older, unmarked graves here, which is common in frontier cemeteries where wooden markers rotted away or graves were never marked at all. Many of the county's early pioneers followed Franklin into this ground, including people who died in a smallpox epidemic in the 1870s. Epidemics like that could take several members of one family within weeks.
One more figure lives here only in local memory. According to tradition, a Kiowa man known as Spotted Tail lies somewhere in the cemetery in an unmarked grave. Nobody can confirm that story, and the marker presents it as tradition rather than fact. Still, it hints that the people who shaped this place were not all newcomers from the East, and that this land had a history long before the Peters Colony arrived.
Its place in the American story
Buckner Cemetery is a small window onto one of the great forces in American history: the colonization of the West through land grants and promises of free land. The Republic of Texas used colonizing companies to draw in settlers, and the United States later did much the same through homestead laws and railroad grants. Families like the McGarrahs and O'Briens were the people who turned those policies into fences, farms, and graveyards.
The site also shows how fragile many frontier towns were. Across the country, early settlements rose and fell depending on where the courthouse, the main road, or the railroad ended up. Fort Buckner was briefly a county seat and is now gone. In countless American counties, a cemetery like this is the only physical remnant of the first town.
The smallpox burials connect this quiet ground to the wider history of disease in nineteenth-century America. Before widespread vaccination and modern public health systems, epidemics swept through rural communities and cities alike, and pioneer cemeteries across the country preserve those waves of sudden loss.
Finally, the tradition of a Kiowa man buried here is a reminder that the story of westward expansion was never only a settler story. Native peoples, including the Kiowa, lived on, traveled through, and defended the Southern Plains. Even when their presence survives only as a remembered name, it belongs in the record of how this country took shape.
If you visit
Come expecting quiet rather than spectacle. This is a pioneer cemetery, the last physical trace of a vanished settlement, and its power lies in what you have to imagine. Picture a trading post, a few cabins, and the business of a brand-new county all happening near here, then notice that only the graves remain.
Walk slowly and read the stones. Look for the O'Brien family names and for clusters of burials from the 1870s, which may reflect the smallpox epidemic the marker describes. Keep in mind that some of the most important graves here may have no marker at all, including the unmarked grave that local tradition gives to a Kiowa man named Spotted Tail. Watch where you step, and treat the grounds with the respect owed to any burial place.
The cemetery also carries a Historic Texas Cemetery designation, added in 2001, which recognizes it as a historic burial ground worth protecting. A visit pairs naturally with exploring McKinney, the city that eventually became the seat of Collin County, where you can trace how the county's public life moved on from Buckner.
For a road trip through North Texas history, this is a good place to slow down. Today it sits in one of the fastest-growing regions in the country, and the contrast is the point. All around you is twenty-first-century suburbia, and right here is a patch of ground that still remembers the 1840s.

Site of Buckner
McKinney, TX
John (Jack) McGarrah and his family came from Tennessee in 1842 and opened a trading post here, becoming among the first settlers of present-day Collin County and defending their family fort against raids. When the county was created in 1846, its seat was laid out here as Buckner, where citizens elected their first officials on the Fourth of July and raised a company for the Mexican War. Found to sit outside the county's legal limits, the seat was moved to nearby McKinney by 1848, and Buckner reverted to farmland.
Muncey Massacre
Plano, TX
McBain Jameson and Jeremiah Muncey settled this vicinity in the early 1840s, when North Texas was still a dangerous frontier of scattered cabins. Late in 1844, hunters came upon the slain bodies of Jameson, the Muncey family, and a small child, along with signs of an Indian raid; a nearby settler's son named Rice was killed as well, and two Muncey boys vanished forever. Remembered as the last such raid in Collin County, the marker was moved to this site in 1998, about a mile from the actual home and graves.
First Presbyterian Church of McKinney
McKinney, TX
Organized in 1874 at the home of local physician Dr. E.N. McAuley, this was the first congregation in Collin County tied to the Presbyterian Church in the United States, a Southern denomination born during the Civil War. From eighteen charter members it grew steadily, outgrowing a modest frame chapel and a brick sanctuary before settling into its present home in 1966, still ringing a bell cast for the fellowship in its earliest years.
Scott Cemetery
McKinney, TX
Scott Cemetery began in the 1850s on the land of pioneer James Preston Scott, whose two-year-old granddaughter, Mary C. Taylor, was the first person buried here. Among its more than 200 graves — at least 30 of them unmarked — are two enslaved people, Jake and Rhoda, laid to rest in the northwest corner. Scott himself, who died while serving in the Texas Legislature, was buried here in 1858, and the ground still serves the surrounding rural communities.
