Founded in 1904 as a private bank by John Walter Knorpp (1867-1952), member of an established banking family of Missouri, New Mexico, and Texas, and Eugene Sherwood Blasdel (1878-1930), oil and grain business developer of this region. In 1905 Blasdel sold his interest to Knorpp. A state charter was obtained in 1908, but surrendered in 1926 for national charter. Patronage from diligent, thrifty early settlers advanced the career of this bank. On its Board of Directors have been members of the pioneer Britten, Fields, Fraser, Harrell, Johnson, Krizan, Slay, and Steele families. I. C. Unsell was cashier from 1908 to 1932. Cecil Culver (born 1903), who came to the bank in 1929 as assistant cashier, purchased the controlling interest from Knorpp and became president in 1951. Adjusting to the crises in the region, State National Bank weathered the panic of 1907, the adversities of the 1930s Dust Bowl, two World Wars, and other national and international experiences. It continues to bolster the cattle, grain, oil, beef feedlot, and other agribusiness interests, and the cultural facilities of Groom and surrounding area

Texas random facts
Carson County, located in the northern region of Texas, has a rich history that dates back to before European settlement. The area was initially inhabited by several Native American groups, including the Comanche, Kiowa, and Apache tribes, who lived off the land and thrived in the surrounding grasslands and rivers.

European settlers began arriving in Carson County in the mid-19th century, drawn by the prospect of vast grazing land and opportunities for ranching. In 1876, the county was officially established and named after Samuel P. Carson, a scout and buffalo hunter. With the arrival of the Fort Worth and Denver City Railroad in the 1880s, the county experienced rapid growth, attracting both ranchers and farmers to the area.

The early 20th century brought economic diversification to Carson County, with the discovery of oil and gas reserves. This newfound wealth fueled further development and population growth in the region. In the 1920s, the construction of Texas State Highway 3 (now known as U.S. Route 60) through the county enhanced transportation, making it easier to access the surrounding cities.

Carson County played a prominent role during World War II, as it became the location of the Pantex Ordnance Plant in 1942. The plant served as a vital component of the Manhattan Project, manufacturing and assembling nuclear weapons. Today, the Pantex Plant continues to operate and plays a significant role in the defense industry, employing many residents of Carson County.

Throughout its history, Carson County has evolved from a land of Native American tribes and open prairies to a thriving community with a diverse economy. It boasts a rich heritage of ranching, farming, oil production, and defense industries. Despite the challenges and changes over time, the county continues to preserve its history while embracing progress and growth.
