McMullen County, Texas: A Genealogical Overview

McMullen County is the heart of the rugged South Texas brush country, a region historically known as the “Wild Horse Desert.” It’s a land forged by a fierce frontier history, deep-rooted ranching traditions, and a legacy of independence. With one of the smallest populations of any Texas county, its story is not one of booming cities but of sprawling ranches, notorious family feuds, and, more recently, the transformative power of the oil and gas industry. For genealogists, tracing roots here means delving into the records of a true Texas frontier.


I. County Formation and Evolution

Like many Texas counties, McMullen existed as an unorganized territory for years before its government was formally established, a critical fact for locating early records.

  • 1858: County Formed: McMullen County was officially created by the Texas Legislature on February 1, 1858.
  • Parent Counties: It was formed from portions of Atascosa, Bexar, and Live Oak counties. Any research for individuals living in the area prior to 1858 must be conducted in the records of these parent counties.
  • 1877: County Organized: Due to its very sparse population and the dangers of the frontier, McMullen County remained unorganized for nearly two decades. During this time, it was attached to Live Oak County for all judicial and administrative functions. The county’s own government was not formally organized until February 14, 1877. This is the most important date for research, as all county-level record-keeping begins then. Any records between 1858 and 1877 will be found in Live Oak County.
  • Name Origin: The county is named for John McMullen, an influential Irish-born empresario who, along with his partner James McGloin, received a grant from Mexico to establish a colony in the region in the 1820s.
  • County Seat History: The first settlement was colloquially known as “Dog Town.” Upon the county’s organization in 1877, the name was officially changed to Tilden in honor of Samuel J. Tilden, who had been the Democratic nominee for president in 1876. Tilden has been the county seat ever since.

II. Settlement and Early History

  • Early Inhabitants: The area was the traditional territory of various Coahuiltecan tribes. During the Spanish and Mexican eras, it was a remote and wild region, famed for the vast herds of mustangs that roamed the brush.
  • Empresario Grants and Frontier Dangers: While part of the McMullen-McGloin colony, the area saw very little permanent settlement due to its remoteness and frequent raids by Comanche and Lipan Apache warriors. Anglo-American settlers began to trickle in during the 1850s, drawn to the vast, unfenced rangeland perfect for raising cattle and sheep.
  • The “Nueces Strip”: McMullen County was part of the lawless “Nueces Strip,” the territory between the Nueces River and the Rio Grande. It was a haven for outlaws and cattle rustlers, and violence was common. The county was a key location in the infamous Sutton-Taylor Feud, one of the longest and deadliest blood feuds in American history.
  • A Ranching Kingdom: The county’s identity is inseparable from ranching. The arid, brushy landscape was not suited for farming, so its economy and culture were built entirely around raising cattle, sheep, and goats on enormous ranches that often spanned thousands of acres.
  • The Oil and Gas Boom: While ranching remains culturally significant, the county’s economy was completely transformed by the discovery of oil and gas. In the 21st century, the development of the Eagle Ford Shale formation made the sparsely populated county one of the leading energy producers in the state.

III. Genealogical Records and Resources

Given its small population, all of McMullen County’s records are highly centralized in the county seat of Tilden.

  • County Courthouse: The McMullen County Courthouse, 202 N. Nueces St., Tilden, TX 78072, is the primary repository for all historical records.
    • County Clerk: This office is the most vital stop for genealogists. It holds land records (deeds), probate records (wills, estates), vital statistics (births, deaths), and marriage licenses dating from 1877.
    • District Clerk: The District Clerk’s office maintains the records of the district court, which include divorce decrees and records of major civil and criminal cases.
  • Vital Records:
    • Birth and Death Records: Statewide registration began in Texas in 1903. The County Clerk serves as the local registrar and holds these records.
    • Marriage Records: Marriage licenses from 1877 to the present are held by the County Clerk. Records for the 1858-1877 period would be found in Live Oak County.
  • Land Records: Records of original land grants from the governments of Spain, Mexico, and the Republic of Texas are archived at the Texas General Land Office in Austin. County-level deeds and property records from 1877 forward are with the County Clerk.
  • Libraries and Museums:
    • The McMullen County Museum in Tilden offers exhibits on the county’s pioneer families, ranching heritage, and frontier history.
    • The McMullen County Library can also be a source for local histories and family files.
  • Bordering Jurisdictions:
