Perhaps you should try some spelling variations:
"heir apparental" » "huir apparental", "her apparental", "weir apparental", "heir apparent", "heir apparently", "heir aparentan"
"heir aparentes" » "huir aparentes", "her aparentes", "weir aparentes", "heir aparente", "heir parente", "heir parientes"
"heir aparentale" » "huir aparentale", "her aparentale", "weir aparentale", "heir aparente", "heir parentales", "heir aparentaba"
"heir parental" » "huir parental", "her parental", "weir 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 aparentes") OR ("heir aparentale"))))) OR ("heir parental"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"heir apparental\") OR (((\"heir aparentes\") OR (\"heir aparentale\"))))) OR (\"heir parental\"))*".
• Removing quotes may allow a broader search: (((( heir apparental ) OR ((( heir aparentes ) OR ( heir aparentale ))))) OR ( heir parental ))*.
