Brideshead is the eldest son of Lord Marchmain and Lady Marchmain, and the older brother of Julia, Sebastian, and Cordelia. Brideshead is a devout Catholic, went to Catholic school, and wanted to be a Jesuit priest before his family persuaded him to go to Oxford. He was deeply affected when his father left home, and has hated Lord Marchmain ever since. Although he is young, Charles observes that Brideshead seems like an old man. He does not seem to have a sense of humor and is unaware and unconcerned when people make fun of him. He makes people feel uncomfortable in social situations but is oblivious to this, which Charles says lends him an air of gravity and commands respect. However, Brideshead is often insensitive and unintentionally hurts people’s feelings. He has boring hobbies, such as matchbox collecting, and has no interest in rebellious or youthful pleasures, such as drinking, dancing, or attending parties. He does not seem to change much as he gets older and seems to take little interest in women. Charles and Julia know little about his life when he is not at Brideshead Castle, and joke about what he may get up to in his spare time. They even joke that he may be a serial killer because he seems so dull and unfathomable to them. His mind seems to work slowly, and he has no head for intellectual matters, which stands in the way of his entry into the priesthood. He eventually marries a middle-class Catholic woman named Beryl Muspratt, who feeds him well and has four children from a previous marriage.
