Perhaps you should try some spelling variations:
mary griffiths » mark griffiths, mrs griffiths
r.c griffiths » 6.3 griffiths, r griffiths, sic griffiths
a griffiths » a griffith, _ griffiths, d griffiths
born 1946 » born 1906, von 1946, born 1928
born 1924 » born 1928, von 1924, born 1906
born 16 » born 6, born 1906, born 1965

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: ((((mary griffiths) OR (r.c griffiths))) OR (a griffiths)) (actress, ((((born 1946) OR (born 1924))) OR (born 16))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((mary griffiths) or (r.c griffiths))) or (a griffiths)) (actress, ((((born 1946) OR (born 1924))) or (born 16)))".
• Adding a wildcard symbol may retrieve word variants: ((((mary griffiths) or (r.c griffiths))) or (a griffiths)) (actress, ((((born 1946) OR (born 1924))) or (born 16)))*.
