Ben Here is some information on Robert Armstrong and Alice Calhoun _http://www.tennessee.gov/tsla/history/manuscripts/findingaids/ths889.pdf#sear ch=%22Robert%20Armstrong%20Alice%20Calhoun%22_ (http://www.tennessee.gov/tsla/history/manuscripts/findingaids/ths889.pdf#search="Robert%20Armstrong%20Alice% 20Calhoun") I descend from John Armstrong and Elizabeth Parrott. Elizabeth's Parrott's sister married a William Armstrong. They can both be found in Fayette County, Ohio. There is strong evidence that William Armstrong is the son of John Armstrong and Nancy Agnes Erwin. I believe that John and William are most likely brothers but I don't have strong proof of that. I believe that John Armstrong is a son of John Armstrong b. 1759 and Nancy Agnes Erwin of Highland County, Virginia. Now some researchers indicate that John Armstrong b. 1759 is the son of Robert Armstrong and Alice Calhoun. I've looked into this a bit but I can't straighten it all out in my head. Have you looked into it at all. It seems that you have done a great deal of research on this line. Thanks Ronda
