Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "weir apparent", "hair apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir aparentely" » "huir aparentely", "weir aparentely", "hair aparentely", "heir aparente", "heir apparently", "heir aparentes", "heir aaparenteely", "heir aparentalely"
"heir parent" » "huir parent", "weir parent", "hair parent", "heir aparente", "heir parental"
"her aparenteal" » "her aparente", "her parental", "her aparentan", "her aaparenteeal", "her 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 apparent\") OR (\"her aparenteal\"))) OR (\"heir aparentely\"))) OR (\"heir parent\"))~".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( her aparenteal ))) OR ( heir aparentely ))) OR ( heir parent ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("heir apparent") OR ("her aparenteal"))) OR ("heir aparentely"))) OR ("heir parent"))*.
