there are four records for Klingenberg in telephon-directory of Uelzen /Lueneburger Heide, where Holdenstedt belongs to. I think that you know this, if not I can copy adresses. I've read that you are in South Africa and I have a question: Researching for Klingenberg-name in internet I've found a geographical object KLINGENBERG, may be a mountain, 1519 m. Coordinates 28°28'S/30°28'E. This is north from Pietermaritzburg, east from Ladysmith, mountains "Drakensberge". Do you know this? Why it is named Klingenberg?
