Perhaps you should try some spelling variations:
heir » her
apparental » apparent, apparently, aparentan, apparente, apparenteal, apaparenteal, apapparental
parental » parente, parenteal, aparenteal, apparental
aparentes » aparente, patentes, parente, aparentees, aaparentees, aapparentes
parent » parente, aparente, apparent
parents » parentes, aparentes, apparents, parente, patents, aparente

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 parental) ) OR ( heir aparentes ))) OR ( heir (parent OR parents) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( heir (apparental OR parental) ) OR ( heir aparentes ))) OR ( heir (parent OR parents) ))*".
