DOYLE, TEXAS. Doyle, five miles northeast of Groesbeck in east central Limestone County, was known as Shady Grove when the Houston and Texas Central Railway established the town in 1871; when the post office opened in 1903, it was renamed Doyle, in honor of William Elliott Doyle, a former mayor of Mexia. In 1914 the community had a grocery store and a general store. The post office was discontinued in 1923, and mail for Doyle residents was sent to Groesbeck. County highway maps in the late 1940s showed a church, a business, and a number of residences at the site. Doyle reported a population of ten in 1990. The population grew to fifty by 2000.
