Re: A.G. Pirkle from Hall County, GA
Albert G Pirkle is also listed in the index to Georgia's 1867-1868 returns of Qualified Voters and Registration Oath books. His listing is 129:13, the volume and page of the directory of returns. His listing for the volume and page of the oath book is 241:184. These indexes are located at the Ga Dept of Archives and I believe you can contact them and pay for a copy if you don't want to go to the archives.
This should at least prove that he was still around and where he was in the 1867-1868 period.
