Artist's Rendering of Forest Home Plantation The Trinity area began to be settled as early as the 1810s as plantation owners built homes on the elevated site to escape the plague of mosquitos in the lowlands, where their plantation houses stood. A Methodist church had been established by 1820. Trinity's first post office was established in 1848 but closed in 1853. The area was known for its rock quarries in its early years and also served as a stagecoach stop. The post office was reopened in 1866, and the town took on the name Trinity Station. Public education lagged in the town, as most of the large landowners had private tutors for their children. The first public school in Trinity evolved out of the plantation school started by John A. Lile and in 1874 opened as the private Mountain Springs School. Lile's son Henry expanded it and renamed it Lile College in 1900. He would go on to serve as superintendent of Morgan County schools in the late 1890s. Trinity Station incorporated in 1901, and residents changed its name back to Trinity in 1903.
