Marlin, have begun a preliminary search for your ancestor, Richard (or Radford) Norton, who you said was killed in the battle for Fredericksburg in Dec 1862, a member of the 25th NC Infantry.
Sorry I didn't get back to you sooner, but I generally don't check my bio area, and, hence, your comment.
The 25th NC Inf lost 12 KIA in the battle of Fredericksburg on 13 Dec 1862. A search of the Fredericksburg National Cemetery turned up nothing for "Norton", and the only "Richard"s buried there were from much later dates, and usually Union.
Still working on it!
