Perhaps you should try some spelling variations:
owen griffiths » green griffiths, roger griffiths, de griffiths
col griffiths » l griffiths, tom griffiths, john griffiths
dot griffiths » d griffiths, de griffiths, tom griffiths
bob griffiths » tom griffiths, john griffiths, _ griffiths

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: ((((col griffiths) OR (owen griffiths))) OR (((dot griffiths) OR (bob griffiths)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((col griffiths) or (owen griffiths))) or (((dot griffiths) OR (bob griffiths))))".
• Adding a wildcard symbol may retrieve word variants: ((((col griffiths) or (owen griffiths))) or (((dot griffiths) OR (bob griffiths))))*.
