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 aparentes" » "her aparentes", "weir aparentes", "hair aparentes", "heir aparente", "heir parente", "heir parientes", "heir aaparentees", "heir aparentales"
"heir parent" » "her parent", "weir parent", "hair parent", "heir aparente", "heir parental"
"huir aparenteal" » "huir aparente", "huir parental", "huir aparentan", "huir aaparenteeal", "huir aparentaleal"

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

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