Perhaps you should try some spelling variations:
"heir apparental" » "her apparental", "weir apparental", "hair apparental", "heir parental", "heir apparent", "heir apparently", "heir apaparenteal", "heir apparentalal"
"heir aparentale" » "her aparentale", "weir aparentale", "hair aparentale", "heir aparente", "heir parental", "heir parentales", "heir aaparenteale", "heir aparentalale"
"heir parent" » "her parent", "weir parent", "hair parent", "heir aparente", "heir parental"
"huir aparentes" » "huir aparente", "huir parente", "huir parientes", "huir aaparentees", "huir aparentales"

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 ((("huir aparentes") OR ("heir aparentale"))))) OR ("heir parent"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"heir apparental\") OR (((\"huir aparentes\") OR (\"heir aparentale\"))))) OR (\"heir parent\"))*".
• Removing quotes may allow a broader search: (((( heir apparental ) OR ((( huir aparentes ) OR ( heir aparentale ))))) OR ( heir parent ))*.
