I have been helping my stepfather with researching his family history and recently came across a tragic coincidence involving two Civil War ancestors. My stepfather's 3 x Great Grandfather Andrew Campbell (38th Indiana Infantry) and 2 x Great Grandfather Samuel Birdwell (Confederate 44th Tennessee Infantry) with both killed in action at the Battle of Perryville on October 8, 1862. Has anybody else come across a situation like this when researching Civil War ancestors?
