A BERMUDIAN married to a member of a prominent British family is the subject of a bizarre case of mistaken identity scandal after London's Daily Telegraph falsely suggested he had fathered his own sister-in-law ¿ at the age of five.

Guy Lancaster's actress wife Kate is the daughter of the late author Norman Mailer and the late British socialite Lady Jeanne Campbell. Her half sister Cusi Cram is a former soap opera star who was the product ¿ the Telegraph mistakenly reported in an obituary of Lady Campbell ¿ of an affair between Lady Campbell and Mr. Lancaster, who was in primary school when his sister-in-law was born.

Mr. Lancaster, a former Warwick Academy student and Bermuda Rhodes Scholar, is the son of retired American International Group executive Jack Lancaster and the late Brenda (Winter) Lancaster.

The huge gaffe was one of several inaccuracies printed by the Telegraph when it ran Lady Campbell's obituary in June.

Her daughters have since declared war on the paper, forcing it to publish an apology it dubbed the "Newspaper Correction of the Month (If Not Year)":

"Our obituary of Lady Jeanne Campbell said she had a daughter, Cusi Cram 'possibly by a man called Guy Nicholas Lancaster.' In fact, Mr. Lancaster is Ms Cram's brother-in-law and was only five when she was born. We apologise to all concerned for our error."

It seems the mea culpa wasn't enough for Lady Campbell's daughters who remain furious over the Telegraph's claims that she had affairs with John F. Kennedy, Nikita Khrushchev and Fidel Castro all in a single year.

"It was such a gross misrepresentation, an example of really bad reporting," Ms Cram told the New York Post.

"She never even met Castro or went to Havana. She was a profoundly intelligent woman and they tried to make her sound sex-crazed and stupid.

"I can't even describe how painful it has been for us."
