The newest member of the royal family was christened Tuesday in the 16th-century Chapel Royal. Prince Andrew and the Duchess of York, the former Sarah Ferguson, stood proudly as as the archbishop of York, John Habgood, christened their 41/2-month-old daughter, Beatrice Elizabeth Mary of York. The godfathers were Viscount David Linley, the duke's first cousin, Peter Palumbo, head of the government's arts council, Duchess Jane of Roxburghe, and two female friends of the Duchess of York. Queen Elizabeth II and Prince Philip joined the godparents at the private ceremony, which included most of the members of both families.
