Perhaps you should try some spelling variations:
"heir apparental" » "her apparental", "weir apparental", "hair apparental", "heir apparently", "heir aparentan", "heir apparentlyal", "heir aparenteal"
"heir parent" » "her parent", "weir parent", "hair parent"
"heir parental" » "her parental", "weir parental", "hair parental"
"huir apparent" » "huir apparently", "huir 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 ("huir apparent"))) OR ((("heir parent") OR ("heir parental"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"heir apparental\") OR (\"huir apparent\"))) OR (((\"heir parent\") OR (\"heir parental\"))))".
• Removing quotes may allow a broader search: (((( heir apparental ) OR ( huir apparent ))) OR ((( heir parent ) OR ( heir parental )))).
• Adding a wildcard symbol may retrieve word variants: (((("heir apparental") OR ("huir apparent"))) OR ((("heir parent") OR ("heir parental"))))*.
