German duchess as the wife of Hereditary Grand Duke Georg Donatus of Hesse and third-eldest sister to Prince Philip, Duke of Edinburgh, the husband of Queen Elizabeth II. Cecilie was born a princess as the third child and daughter of Prince Andrew of Greece and Denmark and Princess Alice of Battenberg. Although her given name was Cecilie, she was known to her family as Cécile.
On 2 February 1931 at Darmstadt, Cecilie married Georg Donatus, Hereditary Grand Duke of Hesse and by Rhine, her maternal first cousin once removed. They had four children.
On 16 November 1937, Georg Donatus, Cecilie, their two young sons and Georg's mother Grand Duchess Eleonore left Darmstadt for London. The aircraft in which they were travelling crashed in flames after hitting a factory chimney near Ostend, Belgium, killing all on board. At the time, Cecilie was eight months pregnant with her fourth child, and the remains of the baby were found in the wreckage. A Belgian enquiry concluded she had given birth mid-flight and the landing attempt was made in bad weather because of this.
Cecilie's daughter Johanna was adopted by Prince Ludwig and Princess Margaret, but she died two years later from meningitis.
Cecilie is depicted in the Netflix series The Crown as Prince Philip's favourite sister. She appears in flashbacks in the second episode and the ninth episode of the second season portrayed by German actress Leonie Benesch.
