ALVARADO, TEXAS. Alvarado, the oldest town in Johnson County, is at the junction of U.S. highways 67 and 81 and Interstate Highway 35W, fifteen miles east of Cleburne in eastern Johnson County. In the winter of 1849 William Balch staked out a claim near an old Indian trail. His family did not last until spring but returned in 1851. Two years later Balch and a fellow settler, G. H. Sigler, laid out half-acre town lots. The community's first sheriff, A. H. Onstoott, is credited with naming Alvarado for Alvaredo, Vera Cruz, Mexico, where he fought in a battle during the Mexican War. By the summer of 1854 Alvarado had an estimated 100 families and postal service. The focus of the town was a two-story building, where the Masonic lodge held its meetings and an elementary school conducted classes.
