Perhaps you should try some spelling variations:
"marcus forth a" » "marcus horeth a", "marcus morton a", "marched forth a", "marcus forth _", "marcus worth a", "marcus forth i"
"marcus foth a" » "marcus 4th a", "marcus horeth a", "marcus enoch a", "marcus roth a", "marcus moth a", "marcus toth a"
"marcus both a" » "marcus 4th a", "marcus bolz a", "marcus box a", "marcus both _"
"marcus ruth a" » "marcus brutus a", "marcus bruan a", "marcus bruun a"
"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 h a") OR ((((((("marcus foth a") OR ("marcus both a"))) OR ("marcus ruth a"))) OR ("marcus forth a")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"marcus h a\") or (((((((\"marcus foth a\") OR (\"marcus both a\"))) or (\"marcus ruth a\"))) or (\"marcus forth a\"))))".
• Removing quotes may allow a broader search: (( marcus h a ) or ((((((( marcus foth a ) OR ( marcus both a ))) or ( marcus ruth a ))) or ( marcus forth a )))).
• Adding a wildcard symbol may retrieve word variants: (("marcus h a") or ((((((("marcus foth a") OR ("marcus both a"))) or ("marcus ruth a"))) or ("marcus forth a"))))*.
