Perhaps you should try some spelling variations:
rusch » rasch, risch, rosch
resch » reach, reich, rasch
busch » buch
leuschel » leuschner, herschel, peschel
puschel » poschel, poeschel
kroschel » koschel, grotschel, poschel

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((rusch OR resch) OR busch) OR ((leuschel OR puschel) OR kroschel)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((rusch OR resch) or busch) or ((leuschel or puschel) or kroschel))".
• Adding a wildcard symbol may retrieve word variants: (((rusch OR resch) or busch) or ((leuschel or puschel) or kroschel))*.
