Perhaps you should try some spelling variations:
"raja mam kwon roy" » "raja m kwon roy", "raja lam kwok roy", "raja kim kwon roy", "raja mam kwon o", "raja mam kwon go", "raja mam kwon ho"
"raja tam kwok roy" » "raja m kwok roy", "raja lam kwok roy", "raja lai kwok roy", "raja lau kwok roy", "raja tam kwok oi", "raja tam kwok y"
"raja j mon roy" » "raja j von roy", "raja j mohon roy", "raja _ mon roy", "raja m mon roy", "raja r mon roy", "raja j moon roy", "raja j monk 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 mam kwon roy\") OR (\"raja tam kwok roy\"))) OR (\"raja j mon roy\"))".
• Removing quotes may allow a broader search: (((( raja mam kwon roy ) OR ( raja tam kwok roy ))) OR ( raja j mon roy )).
• Adding a wildcard symbol may retrieve word variants: (((("raja mam kwon roy") OR ("raja tam kwok roy"))) OR ("raja j mon roy"))*.
