Is there anyone else working on the line of my g-g-g grandfather, Thomas JOHNSON (b. abt 1790-1795, d. abt 1860), mar. Mary UNKNOWN. Their children: Richard M., James, Charles, Adrian, Sarah, Sisson, William, Thomas, maybe Nancy. They moved around, were in Preston Co., VA in 1850, Greene Co.by 1860. I have extensive information on this line, but a few brick walls. Thanks!
