Perhaps you should try some spelling variations:
"raja ram mohan roy" » "raja ram mohon roy", "raja ram mohan r", "raja ram roman roy", "raja ravi mohan roy", "raja m mohan roy", "raja roy mohan roy", "raja _am mohan roy", "raja jam mohan roy", "raja mam mohan roy"
"raja r mohan rai" » "raja r mohana rao", "raja r milan rai", "raja r mohan r", "raja _ mohan rai", "raja j mohan rai", "raja m mohan rai"
"raja o mon roy" » "raja o mohon roy", "raja o kwon roy", "raja _ mon roy", "raja j mon roy", "raja m mon roy", "raja a mon roy"
"raja o von roy" » "raja o von rom", "raja o von rob", "raja o von roh", "raja _ von roy", "raja j von roy", "raja m von roy", "raja 2 von roy", "raja 1 von roy"

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: (((("raja ram mohan roy") OR ("raja r mohan rai"))) OR ((("raja o mon roy") OR ("raja o von roy")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja ram mohan roy\") or (\"raja r mohan rai\"))) or (((\"raja o mon roy\") OR (\"raja o von roy\"))))".
• Removing quotes may allow a broader search: (((( raja ram mohan roy ) or ( raja r mohan rai ))) or ((( raja o mon roy ) OR ( raja o von roy )))).
• Adding a wildcard symbol may retrieve word variants: (((("raja ram mohan roy") or ("raja r mohan rai"))) or ((("raja o mon roy") OR ("raja o von roy"))))*.
