Perhaps you should try some spelling variations:
"hughes griffith, mark griffiths" » "hughes griffith, mary griffiths", "hughes griffith, mrs griffiths", "hughes griffith, a griffiths"
"g griffiths, a griffith" » "_ griffiths, a griffith", "d griffiths, a griffith", "a griffiths, a griffith", "g griffiths, _ griffith", "g griffiths, mr griffith", "g griffiths, mrs griffith"

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, mark griffiths") OR ("g griffiths, a griffith"))*.
• Removing quotes may allow a broader search: (( hughes griffith, mark griffiths ) or ( g griffiths, a griffith ))*.
