Perhaps you should try some spelling variations:
"robert ombres" » "robert morres", "robert nares"
"robert beeres" » "robert beverley", "robert baker's", "robert beverly"
"robert bree" » "robert bruce", "robert breck", "robert bremner"

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