Larry, I live in Heard County and have quite a few names of veterans buried there. (also names I believed to have served, which I am trying to match with records) I will be more than happy to try to find anything I can on your
GreatGrandfather. I will go over my records tonight and see if I already have his name listed, if not I will be doing a lot more research and will gladly let you know if I should find his grave and any marking that may help you. Hopefully since your Grandfather was born in Heard county, your GGrandfather was buried there also.
