Hi and thank you for the findagrave link! I am still trying to locate pictures of the other Arbuckle's that this may be, because there is still a question as to whether it is Abner (from TN), Archibald (from PA), or Alexander (from OH).
see below from Rod Coddington owner of the original
"This image was originally identified as Tennessee-born Abner Arbuckle (1821-1895), who served in Company H of the Fifty-third Illinois Infantry. In October 1862, he suffered a gunshot or shell wound in his left leg and an injury to his breast in action at the Battle of Hatchie's Bridge, fought against Confederate forces retreating after the Battle of Corinth.
On March 25, 2011, I received an email from a descendant of Abner Arbuckle who raised concerns about the identity of the sitter, citing a period description that notes Abner Arbuckle had gray hair and a face scarred by smallpox.
As a result, I've changed the status of this image from identified to unidentified.
There are only two other men with the first initial A and the last name Arbuckle that served during the war: Alexander Arbuckle of the Ninety-seventh Ohio Infantry and Archibald Arbuckle of the Twenty-ninth Pennsylvania Infantry. It may be one of them. If you have any information that might lead to a positive identification, please email me or a leave a comment"
I will update this as soon as we can make a definite ID on this photo. Thanks again!! Barb
