Perhaps you should try some spelling variations:
"marcus forth a" » "marcus foth a", "marcus horeth a", "marcus morton a", "marcus forth _", "marcus worth a", "marcus forth i"
"marcus both a" » "marcus foth a", "marcus ruth a", "marcus 4th 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"marcus h a\") OR (((\"marcus both a\") OR (\"marcus forth a\"))))".
• Removing quotes may allow a broader search: (( marcus h a ) OR ((( marcus both a ) OR ( marcus forth a )))).
• Adding a wildcard symbol may retrieve word variants: (("marcus h a") OR ((("marcus both a") OR ("marcus forth a"))))*.
