Charles spoke warmly about his cousin in his speech, saying: He said: "I can't resist saying a few very small words because above all, I wanted to pay a very special tribute to darling Catherine [Goodman] who, can you believe it, it all goes back really to when my very special cousin, Sarah [Chatto], and Catherine were young 18-year-old students at Camberwell School of Art and used to come bouncing into my room. I remember that was where it all started."

Lady Sarah and Daniel married on 14 July 1994 at St Stephen's, Walbrook, in the City of London.
