My ancestor Hartwell F. Barham was supposedly in "Capt. Mason's Co. 15th Virginia Regiment." I'm having a hard time finding info on that unit, let alone Hartwell Barham. Hartwell would have been over 50yrs. old. I've found Hartwell F. Barham in Tennessee, which was a son of the earlier mentioned Hartwell. Anyway if anyone can help find info on unit, or roster listing Hartwell Barham in the 15th Virginia it would be appreciated.
