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 grands", "lawrence b. de grandi", "lawrence b. le grand"
"lawrence j. de grande" » "lawrence _. de grande", "lawrence j. de gran", "lawrence j. de grandse", "lawrence j. de grandie", "lawrence j. le grande"

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