If you head south on Hwy. 56 from McMinnville, heading toward Beersheba Springs...you will find the cemetery. The area is known as Mount Olive and there's a school there in front of the cemetery called Cedars of Lebanon Academy. It's just across the Warren/Grundy County line in Grundy County. If you cross the Collins River bridge, you've gone too far.
If you're heading South, you'll need to turn left into the road leading to the cemetery.
I have a book that lists some of the people buried in the cemetery (my grandparents and others buried there). Please e-mail me if you'd like me to look up the names for you.
