Spray history:

Spray was named for a prominent stockman, John Fremont Spray, who settled at the site of Spray in 1900; his wife filed the town plat that same year, on May 19. The post office was established a few days later with Spray as postmaster. Spray was the latest and last community to incorporate in Wheeler County. Not until February of 1958 did the town officially file incorporation papers with the state.
