Perhaps you should try some spelling variations:
"lawrence b. de grand" » "lawrence _. de grand", "lawrence a. de grand", "lawrence h. de grand", "lawrence b. de grande", "lawrence b. de grands", "lawrence b. de grandi"
"lawrence j. de grand" » "lawrence _. de grand", "lawrence j. de grande", "lawrence j. de grands", "lawrence j. de grandi"

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: "((\"lawrence b. de grand\") OR (\"lawrence j. de grand\"))".
• Removing quotes may allow a broader search: (( lawrence b. de grand ) OR ( lawrence j. de grand )).
• Adding a wildcard symbol may retrieve word variants: (("lawrence b. de grand") OR ("lawrence j. de grand"))*.
