Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "hair apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir aparentalely" » "huir aparentalely", "her aparentalely", "hair aparentalely", "heir parentales", "heir aaparentealely", "heir aparentalalely"
"heir parent" » "huir parent", "her parent", "hair parent", "heir aparente", "heir parental"
"weir apparent" » "weir apparently", "weir aparente", "weis apparent", "wei apparent", "weil apparent", "weir apaparente", "weir apparental"

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 (\"weir apparent\"))) OR (\"heir aparentalely\"))) OR (\"heir parent\"))~".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( weir apparent ))) OR ( heir aparentalely ))) OR ( heir parent ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("heir apparent") OR ("weir apparent"))) OR ("heir aparentalely"))) OR ("heir parent"))*.
