Thanks Chuck.
I honestly do not know which A. J. Dunn may be buried in
McGavock Cemetery. I have used every source I know to try and separate the two men. Perhaps Mr. Howell made a mistake and got Regt. and Batt. confused, I just do not know.
If it is your desire we can write him and ask for his assistance or we can contact Mr. Eric Jackobson who has reserached and wroteabout the burials at the cemetery. Here is a link to his book.

If you are satisfied that the A. J. Dunn listed is your ancestor, that is fine also. Regardless of your decision, I wish you luck in locating the truth.
