I believe that I have seen this line on ANCESTRY.COM. Seems like the line was from John Sing, Jr. I think, from the best I can remember, that John Sr. was originally listed in Charles Town county. Even if you are not a member of Ancestry.com, you can find some limited info. Try it and let me know if you find what you need. I do remember that John Jr. moved to Tennessee and had a bunch of offspring. I, too have Sings in my family.
