Perhaps you should try some spelling variations:
"heir apparental" » "huir apparental", "her apparental", "hair apparental", "heir parental", "heir apparent", "heir apparently"
"heir aparentes" » "huir aparentes", "her aparentes", "hair aparentes", "heir aparente", "heir parente", "heir parientes"
"heir parent" » "huir parent", "her parent", "hair parent"
"weir parent" » "weis parent", "wei parent", "weil parent"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("heir apparental") OR ("heir aparentes"))) OR ((("heir parent") OR ("weir parent"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"heir apparental\") OR (\"heir aparentes\"))) OR (((\"heir parent\") OR (\"weir parent\"))))*".
• Removing quotes may allow a broader search: (((( heir apparental ) OR ( heir aparentes ))) OR ((( heir parent ) OR ( weir parent ))))*.
