Perhaps you should try some spelling variations:
"robert richardson" » "robert wichard", "robert riceardson", "robert priceardson", "robert richardardson"
"robert patten" » "robert watt", "robert parker"
"robert payne" » "robert parker", "robert paul", "robert vyner"
"robert rich" » "robert rice", "robert price", "robert richard"

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: (((("robert rich") OR ((("robert payne") OR ("robert patten"))))) OR ("robert richardson")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"robert rich\") or (((\"robert payne\") OR (\"robert patten\"))))) or (\"robert richardson\"))".
• Removing quotes may allow a broader search: (((( robert rich ) or ((( robert payne ) OR ( robert patten ))))) or ( robert richardson )).
• Adding a wildcard symbol may retrieve word variants: (((("robert rich") or ((("robert payne") OR ("robert patten"))))) or ("robert richardson"))*.
