I also received today (30 Aug, 2002) a notice for the Clabuesch family book. We also are a very small family, likely less that 100 Clabuesch's in the world. I have traveled to over 50 countries with the State Department in almost all continents and never seen a Clabuesch listed in a phone book or directory.
We know when gr-grandpa come to the US from Germany and he was the last male Clabuesch in Germany. Tough to have "hundreds" and go back 200 years.
