Thanks for the reply.
Is your 3rd great Uncle's grave site registered? Everywhere we look contains no records about this cemetery.
As far as the unmarked graves, we maybe able to help. I have students working on gathering as much info about this cemetery as they can. Once they have enough info, we maybe able to have a group called 'CAST' from the University of Arkansas come and do a scan of the area to find unmarked graves.
If you'd like to share whatever info you have, please email me at firstname.lastname@example.org
In regard to the Boltman Wells cemetery, my 3rd great uncle is buried there. It is David's military headstone that was probably the one that they noticed. Many of my ancestors are there in unmarked graves. I've actually contacted a company that does GPR surveys of burial grounds to find unmarked graves. Do any of you know who the current owner of the property is?
