Who is this person?

I think one of Grant's daughters is buried there.
Usually I will double check Google to see if I'm right, but in this case …..

Well done, my friend! You are correct.

The All-Knowing Google will tell you that Ellen Wrenshall "Nellie" Grant Sartoris Jones, the third child, and only daughter, of Ulysses S. and Julia Dent Grant ("Wrenshall" was Julia's mother's maiden name -- no extra charge for that tidbit) is buried with her second husband, Frank Hatch Jones, in Oak Ridge Cemetery.

Your prize is something you already had: my very best wishes to you and your family for a Happy and Healthy 2019!!!
