Searched on Http://www.civilwardata.com and found two references to Peter H. Light. One enlisted on 10/22/62 as a private in COMPANY H. PA 3rd Heavy Artillery Pennsylvania Volunteers, was mustered out on 7/25/65 after the end of the War. \The other Peter H. Light enlisted on 9/12/62 as a Private into Company B. PA 11th Infantry and was mustered out on 9/25/62 in PA Volunteers. From the Dates it is unlikely that these are the same person. I think there was another Peter Light, and Peter H. Light from Illinois. I c an get you other information, such as outfit casualties, and Regiment Battle history if there is a way to identify which John H. Light is correct, or I get both. I have signed up for this service - I think $25 a year to research as much as you want. Earl earl@shay.net
