I am unfamiliar with any of the names you are researching. However, there is an old cemetery just 1 1/2 mile above the Hurley, VA Post Office located on the side of a hill. It is a very old cemetery, with many unmarked gravesites. I am very sorry that I don't know the name of it but anyone who lives in Hurley, VA should be able to give you directions. You might try googling Hurley, VA Post Office and you might find other sources with phone numbers where you may be able to pose questions. (The cemetery is on Lester's Fork of Knox Creek as I recall.)
You might try writing to the Buchanan County Historical Society, Grundy VA zip code I don't know. Also, try writing to the Buchanan County Courthouse library located in Grundy, VA. They might be able to help you. Good luck.
