Perhaps you should try some spelling variations:
"raja ram mohan roy" » "raja r mohan roy", "raja ram mohon roy", "raja ram mohan r", "raja ram mohan rai", "raja ravi mohan roy", "raja roy mohan roy"
"raja o kwon roy" » "raja o kwon o", "raja o kwon go", "raja o kwon ho", "raja _ kwon roy", "raja j kwon roy", "raja r kwon roy"
"raja m mon roy" » "raja m von roy", "raja m mohon roy", "raja _ mon roy", "raja j mon roy", "raja r mon roy", "raja m mona roy", "raja a mon roy"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja ram mohan roy\") OR (\"raja m mon roy\"))) OR (\"raja o kwon roy\"))*".
• Removing quotes may allow a broader search: (((( raja ram mohan roy ) OR ( raja m mon roy ))) OR ( raja o kwon roy ))*.
