Princess Marina, Duchess of Kent from 0 to 61 years old

Princess Marina of Greece and Denmark (December 13, 1906 - August 27, 1968) was a Greek princess by birth and a British princess by marriage. Born in Athens, Greece, she was the third and youngest daughter of Prince Nicholas of Greece and Denmark and Grand Duchess Elena Vladimirovna of Russia. Her father was the third son of George I of Greece and Queen Olga, while her mother was the only daughter of Grand Duke Vladimir Alexandrovich and Grand Duchess Maria Pavlovna of Russia.
Marina spent her early years in Greece, and lived with her parents and paternal grandparents at Tatoi Palace. Along with her sisters Olga and Elizabeth, she was raised to be devout and religious, which was encouraged by her grandmother, Queen Olga of Greece. Marina's family travelled outside of Greece often, especially during the summer months. Her first recorded visit to Britain was in 1910, when she was 3, after the death of her godfather, Edward VII. During that visit, she met her other godmother and future mother-in-law, Queen Mary, who treated Marina and her sisters like her own children. The Greek royal family was forced into exile when Marina was 11, following the overthrow of the Greek monarchy. They later moved to Paris, while the Princess stayed with her extended family throughout Europe.
Princess Marina met Prince George, Duke of Kent, fourth son of King George V and Queen Mary, in 1932. Their betrothal was announced in August 1934. Prince George was created Duke of Kent on October 9, 1934. On November 29, 1934, they married at Westminster Abbey in London. They had three children: Prince Edward, Princess Alexandra, and Prince Michael. Marina became very close to her mother-in-law, Queen Mary, with whom she would usually spend time while her husband was off performing his own royal duties.
She was widowed in 1942, when her husband was killed in a plane crash on active service. In later life she carried out many royal engagements, including the independence celebrations for Ghana and Botswana. During World War II, Marina was trained as a nurse for three months under the pseudonym "Sister Kay" and joined the civil nurse reserve.
After her husband's death, the Duchess of Kent continued to be an active member of the British royal family, carrying out a wide range of royal and official engagements. She was the president of the Wimbledon All England Lawn Tennis and Croquet Club for 26 years. She was also the president of the Royal National Lifeboat Institution from 1943 until her death and was awarded the RNLI's gold medal in 1967 to mark this contribution. One of her first cousins was Prince Philip (later the Duke of Edinburgh), who married her niece, the future Queen Elizabeth II.
As the patroness of several organizations and charities, including the Elizabeth Garrett Anderson Hospital, the Women's Hospital Fund, and the Central School of Speech and Drama, she continued to support these charities and institutions for the rest of her life.
Princess Marina died of a brain tumour at Kensington Palace on August 27, 1968, at age 61.
