Perhaps you should try some spelling variations:
"richard clarke" » "richard claridge", "richard parker"
"richard carew" » "richard carter", "richard harvey", "richard ward", "richard crew", "richard coxrew", "richard wardrew"
"richard ca" » "richard c", "richard cox", "richard ward"

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: (((("richard carew") OR ("richard ca"))) OR ("richard clarke")).
• Removing quotes may allow a broader search: (((( richard carew ) or ( richard ca ))) or ( richard clarke )).
• Adding a wildcard symbol may retrieve word variants: (((("richard carew") or ("richard ca"))) or ("richard clarke"))*.
