There’s only one Victorian sculpture in Laurel Grove South Cemetery, the historic Black cemetery in Savannah. It happens to be a John Walz, of Gracie fame. I am unable to confirm much about John and Clara Davis. At one point, I read they were shopkeepers, but I cannot recall the source.
John Walz was a German-American sculptor who moved to Savannah after visiting to help install monuments his company made for the Telfair Museum. My understanding is that no one is certain how many monuments he made for cemeteries, but it’s well-above 80.
