Perhaps you should try some spelling variations:
johannes liesche » johannes basch, johannes bosscha, johannes kiess
johannes berchem » johannes becker, johannes berger, johannes bechteln
johannes fischer » johanna fischer, johan fischer, johannes fechner

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: ((((johannes liesche) OR (johannes berchem))) OR (johannes fischer)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((johannes liesche) OR (johannes berchem))) or (johannes fischer))".
• Adding a wildcard symbol may retrieve word variants: ((((johannes liesche) OR (johannes berchem))) or (johannes fischer))*.
