I am looking for photo of Linus Shepard Ludington who served in the Civil War under the 1st Connecticut Heavy Artillary. Linus befriended my gr-gr-gr uncle Gilbert L. Mixter who served in the 1st Massachusetts Cavalry and died in the Andersonville Prison. What I believe was a means to commemorate their friendship, Linus kept a note in his wallet stating Gilbert's passing at the prison. I am trying to learn more on how these two men met and would like to associate faces with the men. Thanks.
