I am trying to find my Union ancestor who fought in the Civil War. From my GrandFather, he is not with us anymore, he told me that my ancestor was from Philadelphia, Pa. He was captured at Gettysburg, Pa, and was at Libby Prison. His last name was Myers. Is there a list of Pa soldiers captured at Gettysburg? Or a list of prisoners that were at Libby prison or in Richmond.
Thank you, Ken
