In an attempt to verify that my ggg grand uncle, Henry Raley, 9th infantry, Co. D was indeed present at the Wheatfield (Gettysburg). I've been to the National Archives and unfortunately his service record is incomplete for that period. Would appreciate it if anyone knows if I can get a roster of the soldiers present in the battle. My concern is that he may have been on furlough and I would like to verify that. Thanks much!
