Hello ENail2593 -

I don't have information, personally in my line regarding Elizabeth Nail, but I do see a lot of info out there.
I also remember just having seen this obit.

And, maybe you've already seent this, but if not:

I don't know about any of the documented facts (it's not my research), but it is the James and Elizabeth you are inquiring about.

My James GARRETT was also married to an Elizabeth (REYNOLDS), and is buried at Springtown Cemetery, Springtown, ARK.

** I also ran across some books last night, that mentioned Elizabeth NAIL and James GARRETT. I'll see if I can get it again and send over.
