"Alexandra is the daughter of Prince George, Duke of Kent, and Princess Marina of Greece and Denmark. She is a first cousin of the current British monarch, Queen Elizabeth II, and since her mother was a first cousin of the queen's husband, Prince Philip, Duke of Edinburgh, she was also his first cousin once removed.

Alexandra is the widow of businessman Sir Angus Ogilvy, to whom she was married from 1963 until his death in 2004.

At the time of her birth, she was sixth in the line of succession to the British throne and as of January 2022 she is 57th."
