Perhaps you should try some spelling variations:
"marcus forth i" » "marcus foth i", "marcus horeth i", "marcus morton i", "marcus forth _"
"marcus ruth a" » "marcus brutus a", "marcus bruan a", "marcus bruun a"
"marcus both a" » "marcus foth a", "marcus 4th a", "marcus bolz a", "marcus both _"
"marcus h a" » "marcus _ a", "marcus a a", "marcus j a"

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 ruth a") OR ("marcus h a"))) OR ((("marcus both a") OR ("marcus forth i")))).
• Removing quotes may allow a broader search: (((( marcus ruth a ) or ( marcus h a ))) or ((( marcus both a ) or ( marcus forth i )))).
• Adding a wildcard symbol may retrieve word variants: (((("marcus ruth a") or ("marcus h a"))) or ((("marcus both a") or ("marcus forth i"))))*.
