She died peacefully at her home in Northwood, London on Sunday (25Nov12).

The star, born Dinah Ginsburg, changed her surname while auditioning for the role of Wendy in a theatre production of Peter Pan, later making her film debut in 1937.

She is perhaps best known for her appearances in U.K. films The Railway Children and Genevieve, as well as in TV sitcoms Don't Wait Up and All Night Long. In 1983, Sheridan played Time Lady Chancellor Flavia in Doctor Who 20th anniversary special The Five Doctors.

The beauty was married four times - she was wed to former child star Jimmy Hanley for 10 years and she ended her 11-year union with business executive John Davis in 1965. She was also the wife of stage actor John Merivale and Aubrey Ison.
