My late husband was a great great grandson of Issac Fletcher and Elizabeth.I was unaware of your ancestor Charles as I only show 8 children under Issac and don't have a Charles. However. as with all family historians, I'm sure I have a lot more holes in my data files. Issac was born 7 July 1809 and I have two conflicting places of birth, one NC, one TN. still tracking that.Elizabeth Langford b. 18 Aug 1816, Scott Co, VA.Marriage for these two is 2 Oct 1831 from the Scott Co.VA Marriages 1815-1839. If you can give me any information on your Charles, son of Issac, I will add it to my data for future reference.My husband's DNA is part of the Fletcher DNA project and we have found one other descendent of Issac from that effort.That branch is in KY.Don't know how much this helps, but I believe if we all share, that sooner or later we can solve these mysteries.
