The roster of the 122nd Pennsylvania Volunteers has been posted on Rootsweb at ftp://ftp.rootsweb.com/pub/usgenweb/pa/lancaster/military/122pavol.txt This regiment was organized August 12, 1862 and mustered out May 16, 1863. Most if not all were from Lancaster County. It is listed with officers first then privates in alphabedical order, for each company. Hope this helps someone. Marge Green
