Perhaps you should try some spelling variations:
marcus brutus » marcum brutum
marcus bruun » marcus bruan, marcus bull, marcus gunn
marcus foth » marcus 4th, marcus horeth, marcus enoch
marcus ruth » marcus bruan

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: ((marcus foth) OR (((((marcus ruth) OR (marcus bruun))) OR (marcus brutus)))) a.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((marcus foth) or (((((marcus ruth) OR (marcus bruun))) or (marcus brutus)))) a".
• Adding a wildcard symbol may retrieve word variants: ((marcus foth) or (((((marcus ruth) OR (marcus bruun))) or (marcus brutus)))) a*.
