On May 6, 1992, Mayor Rudy Kelley received a letter from Mr. John Stockbridge of South Carolina requesting a letter of "Greeting" from the City of Stockbridge to the attendees of the first reunion of the Stockbridge family. In his letter, he mentioned that he grew up in Georgia and had been told as a child that the City of Stockbridge was named after his great-great-grandfather Levi Stockbridge who traveled back and forth from the north to his property in Florida and stopped here on his journey.
Levi Stockbridge was born on March 13, 1820, and fits the time frame just prior to the Civil War. Levi would have been 27 years of age when Stockbridge was assigned a post office in 1847.
Until May 6, 1992, there had never been a name other than Professor Stockbridge. At that time, Levi Stockbridge was mentioned as the person for whom the city may have been named.
It is not certain that Levi Stockbridge was the individual for whom the citizens of the community named their post office and village. However, through John Stockbridge’s letters and many conversations with him, it is believed that this is the rightful Professor Stockbridge who had been unknown for 146 years.
