Perhaps you should try some spelling variations:
mam mohan » ram mohan, rama mohan, jai mohan
mohan roy » mohon roy, mohan r, mohan rai
raja mam » raja m
m morton » mr morton, _ morton, j morton
m moxon » mr moxon, j moxon

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 mam mohan roy ) OR ( raja ((m moxon) OR (m morton)) roy )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja mam mohan roy ) or ( raja ((m moxon) OR (m morton)) roy ))".
• Adding a wildcard symbol may retrieve word variants: (( raja mam mohan roy ) or ( raja ((m moxon) OR (m morton)) roy ))*.
