Hello, Charles.

I'll give you the highlights from the service records of each.

Alexander C. Dennard - Co. B, 14th GA Inf. Died of dysentery, 10/26/1864, at Jackson Hospital, Richmond, VA

Charles Dennard - Co. B, 14th GA Inf. Captured 5/23/1834 @ North Anna River, Va.; Paroled @ Pt. Lookout, MD;
and exchanged 3/14/1865.

George Dennard - Co. B, 14th GA Inf. was killed in battle, 5/31/1862 (Seven Pines , VA ?)

I found all this online via subscription on Fold3. If you are in the Atlanta area you can also see their
compiled service records on microfilm @ the Georgia Dept. of Archives & History in Morrow, just
south of town off I-75.

Hope this helps.

Sincerely,

Greg
