I'll have to research it for you, but I believe the Shawnee Country Club was formed in 1909. The Shawnee course, always thought of as the resort course for the Buckwood Inn, which it was, was also the home site for the Shawnee Country Club.
These has always been some question, inmy mind, whether or not the course was built for the Club with the Inn benefiting from it as Worthington was behind both, or that it was built for the Inn and the Club was just a lesser partner in it.
There is some support for both sides...
