Perhaps you should try some spelling variations:
johannes fischer » johan fischer, johannes fechner, johannes liesche
johannes berchem » johannes becker, johannes berger, johannes bechteln
johanna fischer » johan fischer, johanna kissler, johanna borchert
johannes picht » johannes wicht, johannes richter, johannes fuchs

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