Many thanks, Jay, for offering forth your own personal experiences re this matter. Your remarks, indeed, are helpful to me....and I am sure to other researchers! The voice of experience is important and helpful as I begin to plan for this endeavor.
Note: One of the main research librarians in the Birmingham research library gave a copy of information posted by you (from another site) re locating old graves.I found it quite interesting!
In one reading selection, I found that in even in the locations of the very oldest graves, there appears to be, perhaps, a magnetic field which surrounds the physical remains of the deceased (it is a field of some type of force); and this is true even if the old wooden coffin no longer exists. This particular field radiates out about eight feet from the grave. Note: I do not recall if this was info in the posting which you made, or if it belonged to another writer.Anyway, I deemed this information most interesting to ponder.When I have additonal time, I will research this further...
Again, thank you for your remarks re your first-hand experiences....such broadens my vision re the issue of searching for old graves!
