Perhaps you should try some spelling variations:
"otten simon davies" » "otten simon david", "otten wilson davies", "otten ian davies", "cotton simon davies", "potter simon davies", "patten simon davies"
"cohen setton dawes" » "cohen seth dawes", "cohen setting dates"
"cohen simon dawes" » "cohen timo dawes", "holden simon dawes", "cohen simon dale", "cohen simon das", "cohen simon mawer's"

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: (("otten simon davies") OR ((("cohen setton dawes") OR ("cohen simon dawes"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"otten simon davies\") or (((\"cohen setton dawes\") OR (\"cohen simon dawes\"))))*".
• Removing quotes may allow a broader search: (( otten simon davies ) or ((( cohen setton dawes ) OR ( cohen simon dawes ))))*.
