I know that Kjelleberg is a farm name in Valle (Aust Agder province) in Norway. People living on this farm were named Kjelleberg. In fact, two of my ggrandfathers were from this farm. If you have more specific info., i.e., date of birth,etc., I might be able to help you as I have a set of reference books from Valle. Also, I am originally from that great state of Minnesota!!
