I am trying to find out if my 3rd great grandfather, William Calvin Loven was one of the 350 or so from the 20th Georgia Infantry (company F ) that fought at Gettysburg. I know that the 20th became part of the Army of Northern Virginia and went to Gettysburg with them. His unit was part of Benning's grigade and fought at Devils Den. I don't know how or where to find the rosters of his company during the dates of Gettysburg. Can anyone help me with this , please? Also, if he wasn't in Gettysburg, where was he at that time? If any help could be given, I would be so appreciative. Thanks so much!
