William Ransom Slaughter was born on January 28, 1823, in Lawrence County, Mississippi, the fifth child of William Webb Slaughter and Nancy Anne Moore. He grew up in a large family alongside siblings George Webb, Mary, Samuel Moore Sr., Rachel, and Nancy J. His family lineage was deeply tied to the early settlement of Texas, and their contributions would become part of the state’s enduring history.
Migration to Texas and Land Grant
In the mid-19th century, William moved westward to Texas, settling first in Nacogdoches before arriving in what would later become Burnet County around 1850. His father, William Webb Slaughter, had received a land grant from Anson Jones, the last President of the Republic of Texas, on August 6, 1845, for services rendered to the Republic. This grant—issued seven years before Burnet County was established—consisted of 26 labors of land on the west side of the Colorado River in Travis County, later part of Burnet County. The tract, estimated at 4,000–5,000 acres, included the present-day site of Granite Mountain, a geological marvel that would later play a pivotal role in Texas history.
Granite Mountain and Texas State Capitol
Granite Mountain, an 866-foot dome of solid pink granite covering 180 acres, became famous when Governor John Ireland insisted on using native Texas granite for the construction of the Texas State Capitol in Austin, rejecting imported limestone. This decision linked the Slaughter family’s land to one of the most iconic buildings in Texas. The granite, formed from molten rock that cooled into large crystals of quartz and feldspar, symbolized Texas strength and resilience. The Slaughter legacy thus became intertwined with the architectural heritage of the Lone Star State.
Family Life and Personal Tragedy
At age 27, William married Sadie May Smith in 1851. Sadie tragically died in childbirth, along with their infant son, Walter, who was buried in the family cemetery. In 1856, William married Sarah Ann Smith, Sadie’s cousin, beginning a new chapter in his life. Together, they raised a large family in a log cabin William built on the homeplace northwest of Marble Falls. Sarah Ann was born on April 1, 1839, and died on May 5, 1909; both she and William were buried in the Slaughter Cemetery on their ranch.
Role in Texas HISTORY
William Ransom Slaughter was more than a rancher—he was a builder of communities and a defender of the frontier. He aided in organizing Burnet County in 1852 and contributed to the development of the livestock industry. He served as an Indian scout under Captain Jeff Maltby, often encountering Native Americans near his homestead, and worked as a freighter for Sam Houston, transporting goods across rugged Texas terrain.
His brother, George Webb Slaughter, played a dramatic role in the Texas Revolution, serving as General Sam Houston’s personal courier. George carried Houston’s order to the besieged garrison at the Alamo, instructing them to retreat—an order tragically ignored, leading to the massacre that became a turning point in Texas independence. George later became a Baptist minister, and his portrait hangs in the Alamo in honor of his service.
Civil War Service
During the Civil War, William served as a 3rd Sergeant in the Texas State Troops, enlisting on January 24, 1864, in Burnet County. His company, organized under the Act of December 15, 1863, was part of the 3rd Frontier District under BG J.D. McAdoo. William served 32 days, earning $80 (minus $0.50 for a powder horn). His unit consisted of 57 men, armed with rifles and pistols, tasked with protecting the Texas frontier during a turbulent era.
Legacy and Impact
William Ransom Slaughter died on March 7, 1908, at age 85, leaving behind a legacy deeply rooted in Texas history. His life spanned the era of the Texas Republic, the Civil War, and the transformation of the frontier into thriving communities. The Slaughter family’s land grant and Granite Mountain became symbols of Texas pride, contributing to the construction of the Texas State Capitol, a monument to the state’s independence and resilience.
Today, the story of William Ransom Slaughter is inseparable from the history of Marble Falls, Granite Mountain, and the broader Texas narrative—a tale of courage, endurance, and vision that helped shape the Lone Star State.
