Perhaps you should try some spelling variations:
"ian duncan scott" » "ian duncan scotus", "ian duncan stone", "a duncan scott", "innes duncan scott"
"jon duncan smith" » "jon duncan sarah", "john duncan smith", "j duncan smith", "colin duncan smith"
"brian duncan smith" » "brian duncan sarah", "bruce duncan smith", "bra duncan smith", "brinnes duncan smith"
"jon duncan sir" » "john duncan sir", "j duncan sir", "colin duncan sir", "jon duncan i", "jon duncan sarah"

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: (((((("jon duncan smith") OR ("jon duncan sir"))) OR ("ian duncan scott"))) OR ("brian duncan smith")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"jon duncan smith\") OR (\"jon duncan sir\"))) or (\"ian duncan scott\"))) or (\"brian duncan smith\"))".
• Removing quotes may allow a broader search: (((((( jon duncan smith ) OR ( jon duncan sir ))) or ( ian duncan scott ))) or ( brian duncan smith )).
• Adding a wildcard symbol may retrieve word variants: (((((("jon duncan smith") OR ("jon duncan sir"))) or ("ian duncan scott"))) or ("brian duncan smith"))*.
