I'm sure you have found the cemetary by now. Just in case, if you're coming out of Columbus on Hwy. 80 towards Geneva, Georgia- you'll see an old white church on the left just outside of town. Turn right onto Ga. Hwy.240. The church will be on the right I'm guessing around ten miles. There is a Nancy Hamilton. Her stone is to itself. Don't know if your Will was buried there unmarked. I am the gggrandaughter of Barney and Rebecca Hamilton Powell who are buried near Nancy and Mattie Lou. If you have any info on a connection with Rebecca, pleas share. I hope I have helped.
