Perhaps you should try some spelling variations:
colin griffiths » col griffiths, john griffiths, alan griffiths
roger griffiths » roger griffin
owen griffiths » green griffiths, de griffiths, e griffiths
dot griffiths » d griffiths, de griffiths, col griffiths
bob griffiths » col griffiths, tom griffiths, john 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: ((((colin griffiths) OR (((owen griffiths) OR (roger griffiths))))) OR (((dot griffiths) OR (bob griffiths)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((colin griffiths) or (((owen griffiths) or (roger griffiths))))) or (((dot griffiths) OR (bob griffiths))))".
• Adding a wildcard symbol may retrieve word variants: ((((colin griffiths) or (((owen griffiths) or (roger griffiths))))) or (((dot griffiths) OR (bob griffiths))))*.
