Famous cattle baron Christopher C. Slaughter died in 1919, and in 1921, his heirs dissolved his cattle company. Slaughter's eldest daughter, Minnie Slaughter Veal, hired an agent to sell her share of the property, and this agent - named Morton Smith - founded the town of Morton. In 1923, the townsite was platted, and Smith's land office was on the east side of the square. In 1924, Morton became the county seat over a town called Ligon. The Slaughters had founded Ligon and were hoping that it would become county seat. Cochran County's western boundary is along the Texas - New Mexico border.
