Thad,
Glad to share what I have. I'm guessing that the NC vet that you are referring to is Billy Mitchell. If you will send me your e-mail address, I'll send you a picture of his stone or better yet, look him up on Find A Grave, there is a picture of his stone. Here is the information I have on the members of the Stonewall Brigade with Montgomery County, IN connections after the war:
