Also, if you added text like "This category was set up as part of the Pittsylvania One Place Study to group ______" to the new category page, then the intent would be clear. People in categorization (me) can't read minds (even though I'm a mom!) and understand the use of the category. It looked like a wrongly named place name to me and I renamed it.
Deb's right though, OPS has specific instructions.
