Toonigh, located between Holly Springs and Woodstock, is also (and more commonly) known as Lebanon.
(The community's original, railroad name is Toonigh, but a few years
later the local post office branch opened as Lebanon.) According to Georgia Place-Names by Kenneth Krakow, the name Toonigh is probably derived from the Cherokee Indian
word "Tooantuh," which means "spring frog" and was also the name of a
Cherokee chief. A popular legend has it that the place was given its
name because it was "too nigh" Woodstock and Holly Springs to become a
full-fledged town of itself. Another story tells that the train station
building - assembled elsewhere and delivered via flatbed rail car - was
originally set "too nigh" to the railroad track.
