In 1854, three families loaded a wagon train pulled by large oxen destined for the coastal prairies of South Galveston County. The land they were heading to was rich coastal land in the upper reaches of Clear Creek. The popular mode of travel was by schooner, but these families would be bringing all their worldly possessions. These families were the Butlers, Cowarts and the Perkins.
The Cowarts built on a creek that carries their name, Cowart Bayou. The Perkins built on a creek they named Magnolia Bayou, because of the beautiful magnolia trees that lined its banks. The G.W. Butler family settled in the area where City Pharmacy is today. Around the 1890s, John League started acquiring property that was available in the Muldoon two-league grant. League purchased this land and became one of the largest landowners in Galveston County. J.C. League's land holdings were quickly building a thriving community. In 1893, League had the area known as Butler Ranch changed to League City. In 1896, while G.W. Butler was postmaster, the city was officially named League City. Soon a local post office "feud" began as the residents of Clear Creek, and the new League City competed for the town's name, as is was controlled by the local post office. The building would be moved back and forth across the railroad tracks as the feud went on, but the name of League City would win out. In 1897, J.C. League donated land for League Park. In 1907, he had two flat cars full of live oak trees left on the siding near the railroad station. They were for the residents of League City to take and plant on their property. G.W. Butler and his son Milby supervised the planting of these trees, which have become the symbol of the city and are known as the Butler Oaks.
