Perhaps you should try some spelling variations:
"a duncan scott" » "a duncan scotus", "a duncan stone", "_ duncan scott", "j duncan scott", "m duncan scott"
"ian duncan sir" » "brian duncan sir", "jon duncan sir", "innes duncan sir", "ian duncan i", "ian duncan sarah"
"ra duncan sir" » "ra duncan i", "ra duncan sarah", "_ duncan sir", "mr duncan sir", "j duncan sir", "r_ duncan sir", "rj duncan sir", "rm duncan sir"

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