You can contact the County directly or contact the LDS church for an interlibrary loan of the book, Revolutionary War Records of Mecklenburg County, Virginia compiled by Katherine B. Elliott. I have also purchased a few of the counties Revolutionary Public Claims books (usually $5.00 to $7.50 a piece)from New Papyrus Publishing Company. DAR books are a good source also. Are you trying to find out whether he was a Patriot or Loyalist? Good luck!
