Lady Amanda Knatchbull, 5th child and 2nd daughter of Countess Mountbatten, and her husband John, 7th Baron Brabourne. Her grandfather, Lord Louis Mountbatten, wanted Amanda to wed his great-nephew, Prince Charles, and eagerly played matchmaker. It was going well until Mountbatten's assassination in 1979 soured Amanda on becoming a member of the Royal Family. She turned down Charles' 1980 proposal where upon he began courting a certain Lady Diana Spencer and the rest, as they say, is history.
