duncan sir » duncan i, duncan sarah
jon duncan » john duncan, j duncan, colin duncan
a duncan » ra duncan, _ duncan, j duncan

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