In the mid-1800s Katy was known as Cane Island, named for the creek that still runs through the area (now a branch of Buffalo Bayou).In 1845 James J. Crawford received a land grant that included this area. The hot summers, cold winters, thick mud and voracious mosquitoes made it difficult to attract settlers to the area. Thirty years later Crawford, John Sills, and freedmen Thomas and Mary Robinson were the only recorded residents of Cane Island. In 1893 theMissouri–Kansas–Texas Railroad (now a part of Union Pacific) started laying rails through Cane Island. The railroad began operation in 1895.That same year James Oliver Thomas laid out a town and in January 1896 the town of Katy was named through Thomas’s post office application. The name was based on the MKT Railroad (which was called ‘the Katy’ by railroad officials) and anticipations of prosperity its arrival would bring to the new town. The town developed around the original train stop and railroad tracks.In 1945 the City of Katy was incorporated as a municipality.
