The Liberty Hill neighborhood was started in 1871, six years after the Civil War. Ismael Grant, Aaron Middleton, William Lecque, and Plenty Lecque bought 111 high acres for $900 and began farming the land. St. Peter's AME Church congregation, first founded by slaves in 1861, came to its present site, in what became Liberty Hill, as early as 1864. Successive generations added numerous homes so that by 1933 while most of the land remained under cultivation there were already about 100 homes in Liberty Hill. Many residents today are proud descendants of the original founders.

Farming gradually gave way to housing that resulted in denser development. World War II brought a dramatic increase in home construction in the adjoining areas of Palmetto Gardens, and John C. Calhoun Homes.

The current Felix Pinckney Community Center honors the grandson of Founder Ismael Grant. Felix Pinckney owned a grocery store where he extended credit and sold vegetables from his garden. He was considered by many the unofficial mayor of Liberty Hill because he was always willing to lend a helping hand to anyone.

Today, there are about 600 homes and a number of small businesses in Liberty Hill.
