I visited Johnathan and Eliza's grave this weekend! I tooks some pictures too. It is located on what is now the "Madison at Ridgelake Apartments" in West Nashville. It is right beside the office to the apartments. There are at least 20 small markers with nothing on them too. I also saw Joseph Minor Hulan's grave, Alfred and E.J. O'brien and his wife, and one for Levi and Martha Maynard. There is another grave near the apartment amerigas tank. It was for a little girl that only lived 9 days; Dec 19-Dec 28, 1929. The footstone said "HMS". I do not recall her name and I don't have my notes right now. I didn't see any marked graves with the name "Hobbs" on it.
Directions to Hobbs Cemetery from Downtown Nashville: Take I-40 west to exit 199 turn left onto Old Hickory Blvd. turn right into the apartments. The small cemetery will be on the left. You will need to turn in as you are going to the apartment office.
