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

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

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