Pippa Middleton, sister to Kate Middleton, the Duchess of Cambridge (see photos of Prince William and Kate's wedding), may get her own royal title one day if she stays with her new reported boyfriend, George Percy, heir to the Dukedom of Northumberland and a $500 million fortune (see photos of the pair). The Percy family's Alnwick Castle (see it) is perhaps best known as the setting for the Hogwarts School in the "Harry Potter" film series.
