Perhaps you should try some spelling variations:
"a duncan scott" » "a duncan scotus", "a duncan stone", "ra duncan scott", "_ duncan scott", "j duncan scott"
"ian duncan sarah" » "ian duncan adam", "ian duncan gray", "ian duncan sir", "brian duncan sarah", "ra duncan sarah", "jon duncan sarah"
"ian duncan shaw" » "brian duncan shaw", "ra duncan shaw", "jon duncan shaw"

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: (("a duncan scott") OR ((("ian duncan sarah") OR ("ian duncan shaw")))).
• Removing quotes may allow a broader search: (( a duncan scott ) or ((( ian duncan sarah ) or ( ian duncan shaw )))).
• Adding a wildcard symbol may retrieve word variants: (("a duncan scott") or ((("ian duncan sarah") or ("ian duncan shaw"))))*.
