Perhaps you should try some spelling variations:
"hugh griffiths, _ griffiths" » "g griffiths, _ griffiths", "nach griffiths, _ griffiths", "hannah griffiths, _ griffiths"
"hughes griffith, mrs griffiths" » "hughes griffith, mrs griffith", "hughes griffith, mark griffiths", "hughes griffith, mary 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: (("hughes griffith, mrs griffiths") OR ("hugh griffiths, _ griffiths"))*.
• Removing quotes may allow a broader search: (( hughes griffith, mrs griffiths ) or ( hugh griffiths, _ griffiths ))*.
