Perhaps you should try some spelling variations:
"mcculloch j. maryland" » "macculloch j. maryland", "mculloch j. maryland", "culloch j. maryland"
"mcculloch john. maryland" » "macculloch john. maryland", "mculloch john. maryland", "culloch john. maryland"

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: "((\"mcculloch j. maryland\") OR (\"mcculloch john. maryland\"))".
• Removing quotes may allow a broader search: (( mcculloch j. maryland ) OR ( mcculloch john. maryland )).
• Adding a wildcard symbol may retrieve word variants: (("mcculloch j. maryland") OR ("mcculloch john. maryland"))*.
