As best I can tell, Thomasville Country Club is now Glen Arven Country Club. It came about as a result of the efforts of a New York lawyer and developer named Jay Wyman, who summered in Thomasville and bought an estate there which was made into the club. The course appears to date from 1895. A Thomasville website claims that the club is the oldest in Georgia and the sixth oldest in the U.S. What I have read credits the design to Wayne Stiles and John Van Kleek, but that would seem to be a later iteration. I suspect there are others here who would know better whether the course is one of Stiles' or no.
An article I have by John Duncan Dunn from 1899, titled "Winter Golf in Southern Sunshine," says of Thomasville:
"The borderland wayside links may fitly end at Thomasville, in the extreme southwest of Georgia, where one can almost imagine that he feels the tang of the Mexican Gulf. Everything about the Country Club of Thomasville betokens taste and judgment, and from the moment you pass through the rustic woodwork arch of its grounds till you leave, there is a sense of luxury and comfort. The home of the club is in Glen Arvern Park, three hundred acres of high ground surrounded by as well-wooded and diversified a country as ever delighted the eye of sportsman and golfer. I found its well-sodded greens and well-turfed course throughout a continuous delight. It did not seem possible that there could be such climatic conditions as those which, in the summerlike parlors of the Piny Woods Hotel, I read of in the North. Fortunate are the golfers of a land where they can so dodge the seasons."
I guess Dunn didn't spend much time there in the summer . . .
