Perhaps you should try some spelling variations:
"d griffiths, mrs griffiths" » "d griffiths, mrs griffith", "d griffiths, mark griffiths", "d griffiths, mary griffiths", "_ griffiths, mrs griffiths"
"g griffiths, a griffiths" » "_ griffiths, a griffiths", "e griffiths, a griffiths", "de griffiths, a griffiths", "g griffiths, a griffith", "g griffiths, _ griffiths", "g griffiths, e 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: (("d griffiths, mrs griffiths") OR ("g griffiths, a griffiths")).
• Removing quotes may allow a broader search: (( d griffiths, mrs griffiths ) or ( g griffiths, a griffiths )).
• Adding a wildcard symbol may retrieve word variants: (("d griffiths, mrs griffiths") or ("g griffiths, a griffiths"))*.
