Capt. Peter F. Tumlinson
Pleasanton, Atascosa County, Texas
Marker Inscription
Peter Tumlinson was 19 years old when his family moved to Texas in 1821. During an 1823 skirmish with Waco Indians, his father, John Jackson Tumlinson, became the first Texas Ranger to die in the line of duty. Peter followed his father into the Texas Rangers. During his forty years of service, Tumlinson clashed with Indian raiders and the infamous Mexican bandit Juan Cortina. He also fought in the Texas Revolution, and family tradition holds that he was present at Sam Houston’s meeting with Santa Anna following the Battle of San Jacinto. For his service, Tumlinson was granted land in Atascosa County, where he served as county commissioner and founded Pleasanton Masonic Lodge No. 283 A.F. & A.M. and served as charter treasurer.

The Story
Peter Tumlinson was nineteen when his family reached Texas in 1821, and he followed his father—John Jackson Tumlinson, remembered as the first Texas Ranger killed in the line of duty—into that frontier service. Over some forty years he clashed with Indian raiders and the border figure Juan Cortina, fought in the Texas Revolution, and by family tradition witnessed the aftermath of San Jacinto. Granted land in Atascosa County, he served as county commissioner and founded the local Masonic lodge.
Why it matters
Tumlinson's long career embodies the violent, formative decades when Anglo, Tejano, and Native peoples contested the Texas frontier.
The story behind this marker
AI contextThe era
The 1820s and 1830s were the raw, formative decades of Anglo-American Texas. When the Tumlinson family arrived in 1821, this was a contested land where new colonists, Tejano residents, and Native peoples met — often violently — along an ever-shifting frontier with little in the way of formal government or protection.
Into that vacuum stepped the earliest ranging companies, the ad hoc mounted bands that would evolve into the Texas Rangers. Their work was hard and dangerous: patrolling vast distances, responding to raids, and enforcing a rough order across country that no regular army covered. Frontier defense was a family affair, and service often passed from father to son.
These were also the years of the Texas Revolution, when the fight for independence overlapped with the ongoing struggles of the frontier. A man of this era might face a Native raiding party one season and a Mexican army the next — the two theaters of danger woven together across a single lifetime.
People & events
Peter F. Tumlinson was nineteen when his family moved to Texas in 1821. Two years later, in an 1823 skirmish with Waco Indians, his father, John Jackson Tumlinson, was killed — remembered as the first Texas Ranger to die in the line of duty. Peter followed his father into that same service, and stayed in it, by the marker's account, for some forty years.
Across those decades he clashed with Native raiders and with the border figure Juan Cortina, and he fought in the Texas Revolution. Family tradition holds that he was present at Sam Houston's meeting with Santa Anna in the aftermath of the Battle of San Jacinto — the decisive encounter that sealed Texas independence. Whether or not every detail can be confirmed, the tradition places him near the hinge of the era's greatest event.
For his long service, Tumlinson was granted land in Atascosa County, and there his life turned from the saddle to civic building. He served as a county commissioner and founded Pleasanton Masonic Lodge No. 283 A.F. & A.M., serving as its charter treasurer — the frontier fighter settling at last into the work of organizing a community.
Its place in the American story
Tumlinson's life traces the whole violent, formative sweep of frontier Texas, and through it, a piece of the larger American story of westward expansion. The struggles he lived through — among Anglo settlers, Tejanos, and Native nations — were the local face of a continental process by which control of the land was fought over, won, and lost.
The Texas Rangers he served in became one of the most storied law-enforcement bodies in American history, and their origins lie exactly in stories like his: informal companies of mounted men, fathers and sons, standing in for a government that had not yet arrived. The death of his father as the first Ranger killed in the line of duty ties this single Atascosa County memorial to the very beginning of that institution.
And the second half of his life matters just as much. The same man who fought across the frontier ended up laying its civic cornerstones — county government, a Masonic lodge, a settled town. That turn, from conflict to community-building, is the arc by which the frontier itself passed into something more permanent.
If you visit
This is a memorial marker in Pleasanton, and it rewards a moment of reflection more than a long walk. Stand with it and consider the span of a single life — from a family's arrival in 1821, through a father's death and a son's forty years of service, to the founding of a local Masonic lodge.
Let the marker do what memorials do best: connect a name to an era. Where the historical record leans on family tradition — as with the claim that Tumlinson witnessed the aftermath of San Jacinto — read it as the community's remembered story of one of its founders, honored here rather than proven in a courtroom.
For a traveler interested in early Texas and the origins of the Texas Rangers, it's a meaningful stop in the Pleasanton area. Pair it with the town's other historic sites and you'll get a fuller picture of how a frontier fought over by many peoples eventually settled into a county with commissioners, lodges, and markers like this one.

Thomas Ransdell Brite
Leming, TX
Born in Missouri in 1824 and raised in Bastrop County, Thomas Ransdell Brite came of age amid the conflicts of early Texas. He volunteered against Mexican incursions in the 1842 Vasquez, Woll, and Somervell campaigns, served in the Mexican War under Captain McCulloch in 1846, and joined the Texas Rangers in 1855 to counter frontier raids. Settling in what became Atascosa County, he was elected its first tax assessor-collector and later county treasurer before his death in 1859.
Mision de las Cabras ("Mission of the Goats")
Floresville, TX
A fortified outpost of San Antonio's Mission Espada, the Mission of the Goats guarded ranchlands along the San Antonio River near a well-known river crossing. Founded in the 1730s era of Spanish missions, it sheltered Indian herdsmen who tended mission cattle, and a chapel was built for their spiritual care. After the missions were secularized in 1794, the land passed to Canary Islander descendants, including the spirited Dona Maria Del Carmen Calvillo, who managed the ranch herself and kept the peace by paying tribute in beef.
Flores Rancho
Floresville, TX
This land began as ranch country for Mission Espada and Rancho de las Cabras, granted by the Spanish crown and once known as Chayopines for the Native people who lived there. By 1756 Juan José Flores kept an adobe house at a river crossing where travelers camped overnight, and that hacienda — encased within a brick house built around it in 1844 — is thought to be the oldest home in Wilson County. Nearby lie the stone foundations of an early-1800s chapel and its campo santo, and the rancho passed through three generations of the Flores family.
Site of Old Town: Lodi
Floresville, TX
By 1720 this land along the river was known as the country of the Cayopines, a Coahuiltecan people, and it became vital to the San Antonio missions, whose herds grazed here tended by herdsmen in adobe huts. Apache raids after 1731 drove those herdsmen to shelter at Mission Cabras, and the ground passed through Spanish ranchos and Canary Islander families before Anglo settler Stephen T. Cook opened a store in 1858 and named the place Lodi. Chosen county seat in 1867, Lodi lost that honor to Floresville in 1872 and reverted to ranching.
