London, May 23 (ANI): The Duke of Northumberland's daughter Lady Catherine Percy's marriage will take place at Alnwick Castle which doubles as Hogwarts in the Harry Potter films.
The royalty is set to marry City financier, Patrick Valentine, in February next year.
Percy trained with the royal gunmakers Purdey and Sons, to later set up a business making stocks for sporting guns.
In March, one of the duke's aides said: "She very much enjoyed her apprenticeship with Purdey and is now a self-employed gun-stock maker."
She worked as chief mechanic for Marquass Motorcycles too.
Valentine works as an equity salesman for Dexion Capital, a hedge fund distribution firm, the Telegraph reported. (ANI)
