THEO, TEXAS. Theo, nine miles southwest of Lott in western Falls County, received a post office in 1895. The office was discontinued in 1904. Theo was the focus of a common school district in the 1930s, when it had a total of twenty-two students. In 1949 the district was divided between the Troy and Oenaville independent school districts in Bell County. A few scattered houses and a cemetery marked the community on county highway maps in the late 1940s, but by the 1980s only the cemetery remained. Population estimates for Theo were not available.
