SENIOR, TEXAS. Senior is a rural community twenty-five miles southwest of San Antonio in extreme southern Bexar County. It was settled in 1875 with a general store, a church, a gristmill, a cotton gin, and a school; later there was also a post office in the general store. The story has it that the town name was derived from children addressing the storekeeper as "Señor." By 1880 the town had a population of 100, by 1890, 200, and by 1910, when the last census of the community was taken, 79. During the 1980s the Senior community was still shown on county maps. At its site were several ruins, including the steps of the general store, and one house that was more than 100 years old.
