Karankawa Indians hunted buffalo on this site as late as the 1820s. Present Fifth Street follows the course of the San Felipe Road, which was opened to Austin's colony in that decade. In 1836 Santa Anna used that road in his march toward San Jacinto. This site was in the 1839 land grant of Republic of Texas citizen James J. Crawford. In 1863 at their camp on San Felipe Road, 35 Confederate soldiers died and were buried in the locality. Cane Island, the original settlement, was known as a stagecoach stop. Developers platted Katy townsite after Missouri, Kansas & Texas Railroad ("The Katy Line") reached this point in 1895. The post office opened Jan. 23, 1896, in the postmaster's mercantile store. In 1897, William Eule grew a rice crop, initiating the locality's major industry. Eule's son Fred dug an irrigation well for the rice fields in 1899.
