While there were reports of a golf club in Savannah dating back to 1795, the Savannah GC that is now in existence was founded in 1899. The first 9 hole course was put in by S. W. Stewart, was extended to 18 holes some time between 1910 and 1916, and around 1912 they reverted back to sand greens after an experiment with grass.
Ross came in around 1927 to remodel the course. I don't have many details on exactly what he did, but I'd guess it included lengthening and rerouting much of the course.
The most interesting aspect of the site is that the course winds around some old Confederate ramparts.
