Smith Family in Lewis & Hardy Co, WV

I have only recently started looking at this site and find that some of you also have Smith connections in WV/VA.  I have traced my line to the Lewis & Hardy Co. area of WV but my 5X great-grandfather's name was John Smith, both very common names and I haven't been able to ID just which John Smith he was, let alone move farther back in time.  His wife was listed as Unis on their son's death certificate (Nimrod C. Smith d.1866 in Lewis Co, WV).  His son was also named Nimrod middle name Bourke and I know his family moved to Ritchie Co, WV and actually know where his grave is.  If any of these names ring a bell with you, please reply to this post.  I'd love to hear from.  Thanks.
