Task: Question Answering
Input (English): Passage: When the entire British royal family is killed in a freak accident outside Buckingham Palace, Sir Cedric Willingham leads a search for any surviving heirs to whom to pass the crown. After days of researching, his team finally locates a living heir in the form of an American named Ralph Jones. Shortly after being fired from his job as a lounge singer in Las Vegas, Ralph is informed by Cedric's assistant private secretary Duncan Phipps that his grandmother Constance had an affair with the first Duke of Warren while working as a hotel waitress when the Duke was visiting the United States, resulting in Ralph having royal blood. Phipps provides further proof by showing Ralph a duplicate of the ring his grandmother used to wear that the Duke had given her.
Ralph is flown to London, where Cedric gives him a crash course on royal etiquette. In only his second day as King, he goes to a strip club and meets Miranda Greene, an out-of-luck exotic dancer and aspiring fashion designer, and dares her to go out on a date with him if the British press proves his claim to the monarchy. Meanwhile, Lord Percival Graves is opposed to having an American on the throne and proposes to declare the reigning House of Wyndham at an end and replace it with the House of Stuart, of which he is patriarch. Prime Minister Geoffrey Hale states that Ralph's succession is legitimate unless he commits a grievous error. With this in mind, Graves bribes a cash-strapped Miranda to stir up controversy by having a public relationship with Ralph. Despite warnings by Cedric not to commit a mistake similar to that of King Edward VIII, Ralph sneaks out of the Palace to have a romantic date with Miranda at Hyde Park. The next day, Miranda returns the money to Graves, but he already has photographs of her with Ralph. In order to preserve Ralph's reputation, Miranda breaks up with him. 
Question: What is the first name of the person that teaches royal etiquette to the man that the head of House Stuart wants replaced?
Output (English): Cedric.
