Perhaps you should try some spelling variations:
"heir apparently" » "huir apparently", "her apparently", "weir apparently", "heir aparentely", "heir apaparentely", "heir apparentally"
"heir apparentally" » "huir apparentally", "her apparentally", "weir apparentally", "heir aparenteally", "heir apaparenteally", "heir apparentalally"
"heir apparent" » "huir apparent", "her apparent", "weir apparent", "heir aparente", "heir apaparente", "heir apparental"
"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.

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