Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "hair apparent", "heir apparently", "heir aparente", "heir apaparente", "heir apparental"
"heir aparentely" » "huir aparentely", "her aparentely", "hair aparentely", "heir aparente", "heir apparently", "heir aparentes", "heir aaparenteely", "heir aparentalely"
"heir parent" » "huir parent", "her parent", "hair parent", "heir aparente", "heir parental"
"weir apparental" » "weir apparentlyal", "weir aparenteal", "weis apparental", "wei apparental", "weil apparental", "weir parental", "weir apparently", "weir aparentan", "weir apaparenteal", "weir apparentalal"

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