John Wesley (1703-1791), founder of what we now call Methodism (the term was originally used as an insult but was eventually adopted by Wesley), and his brother Charles spent some time in Savannah, GA. I lost a bet about that at a dinner party last year, which cost me a bottle of good Montrachet.
Methodism was the ultimate source of our 12-step programs: the Wesleyans liked to have methods for spiritual discipline. John Wesley was an evangelist, and liked to preach outdoors. He tried to convert the Georgia Indians.
He was a "by faith alone" preacher.
He got in a bit of a problem with a Georgia lady, and eventually returned to England. Here's a piece on Wesley in Georgia, and here's a Wesley bio.
The hymns written by John and Charles Welsey are among my favorites. Charles wrote 6000 hymns. John even produced a hymnal but, as this site notes,
Today people are much more familiar with some of Charles Wesley's hymns than with John Wesley's sermons.
