Perhaps you should try some spelling variations:
johannes fischer » johanna fischer, johannes pfister, johannes piscator
johannes liesche » johannes basch, johannes berchem, johannes bosscha
johan fischer » johanna fischer, johann fischart, johan richter

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