So, I called out to Mt. Olivet and… they do have one Susan Allen in the cemetery and it’s definitely an old grave, but they don’t have any information on who that Susan Allen might be. They gave me a section and a lot, so I’m going to check it out later. If that Susan Allen is buried in with Perkinses and Edmonsons (or Edminstons), then we’ll know it’s her.
If not… then the mysterious mystery of where Susan Allen, Nashville medium and, also, professional rich person is buried remains.
