Settled in 1850s by Moses Ball and other pioneers. Tradition says first burial here was an Indian; the second, a small girl who died while her family was migrating through the area. Oldest tombstones are dated 1878. There are many unmarked graves. Community, named for some flat stones that formed a landmark, had a Cumberland Presbyterian Church as early as 1883. Burial ground near church was deeded from his land grant on August 28, 1890, by ex-Texas Ranger George W. Stevens (1831-93) for cemetery. After 1914, population dwindled and the church was closed.
