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

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