Raymond,
Some of the conversation was also on Genforum 10 years ago. Some of them gave up on the quandary as I have been given to understand from a couple of them I have contacted so far. Exactly how did you determine this particular James' or Nancy's parents? I am assuming your John & Nancy were in Berkeley county where the couple were married? I am just looking at the issue now. I noticed someone erroneously attached Nancy to a James and Rhoda McCloy in Ohio on Findagrave and info in online trees varies according to who the treemaker's expert was. The couple is obviously too young to be her parents and who knows if he is even her brother.
McCloy or McClay, documents are still needed.
