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