Perhaps you should try some spelling variations:
reuter martin » sauter martin
peter morris » peter murray, peter moore
peter martin » meister martin, sauter martin, eppler martin
heger martin » weber martin, aigner martin, werner martin

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: ((((peter morris) OR (((peter martin) OR (heger martin))))) OR (reuter martin)) (swimmer).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((peter morris) or (((peter martin) OR (heger martin))))) or (reuter martin)) (swimmer)".
• Adding a wildcard symbol may retrieve word variants: ((((peter morris) or (((peter martin) OR (heger martin))))) or (reuter martin)) (swimmer)*.
