Perhaps you should try some spelling variations:
"heir apparental" » "huir apparental", "her apparental", "weir apparental", "heir parental", "heir apparent", "heir apparently", "heir apaparenteal", "heir apparentalal"
"heir aparentales" » "huir aparentales", "her aparentales", "weir aparentales", "heir parentales", "heir aparentes", "heir parentals", "heir parentaless", "heir aaparenteales", "heir aparentalales"
"heir aparentale" » "huir aparentale", "her aparentale", "weir aparentale", "heir aparente", "heir parental", "heir parentales", "heir aaparenteale", "heir aparentalale"
"heir parent" » "huir parent", "her parent", "weir parent", "heir aparente", "heir parental"

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