Sharon--in searching my Gumz family (they went to Aurora, IL) in Pommern, Prussia (town of Zarnekow, in Kreis Belgard), I found a number of families named Klabunde (on an LDS film). The names from this film have been extracted and appear on the IGI. Have you checked there? I noticed the name because it's so unusual (sometimes in the records it's spelled with a C).
