I have been looking for a book on any georgia units that my relatives were in.No luck so far. 3 brothers and a father all were in the civil war in some respect. From the Militia at Richmond County to the battle at the end. Found where one was paroled, which was the Militia man. The other three served in the 62nd, 20th 9th and the 8th Georgia calvary. Are there any one researching any of these units that can Help?
