Prince Harry's best friend to marry Harry Potter castle heiress Van Straubenzee will be spoiled for choice when it comes to his own wedding venue. His fiancée's family seats are Alnwick Castle in Northumberland, which doubles as Hogwarts in the Harry Potter films, and Syon House in west London. In 2002, Thomas's brother, Henry Van Straubenzee, who was in Prince Harry's class at Ludgrove, was killed in a car crash, at the age of 18. He had gained an Army scholarship and intended to follow a military career, after a planned gap-year adventure working at a bush school in Uganda. His father, Alex, is a former officer in the Royal Green Jackets, who went on to work for The Daily Telegraph. St James's Palace said Princes Harry and William were "very, very upset." The Princes later became patrons of a memorial fund set up in Henry's honour and have attended several fundraising events. In August, Winful Taylor, 27, who caused a security scare by attacking Van Straubenzee in Battersea, south London, as he was talking to Harry on his mobile telephone, was jailed for two years. Because the Prince had overheard the mugging, he gave a police statement.
