Perhaps you should try some spelling variations:
johannes bechteln » johannes becker, johannes buchmann, johannes fechner
johannes fischer » johanna fischer, johan fischer, johannes fechner
johannes berchem » johannes becker, johannes berger, johannes brahms
johanna kissler » johanna fischer, johannes kindler

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 fischer) OR (johannes fuchs))) OR (johanna kissler))) OR (((johannes berchem) OR (johannes bechteln))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((johannes fischer) or (johannes fuchs))) or (johanna kissler))) or (((johannes berchem) OR (johannes bechteln))))*".
