Princess Elisabeth of Denmark, RE (Elisabeth Caroline-Mathilde Alexandrine Helena Olga Thyra Feodora Estrid Margrethe Désirée; 8 May 1935 – 19 June 2018) was a member of the Danish royal family. She was the only daughter and eldest child of Hereditary Prince Knud and Hereditary Princess Caroline-Mathilde of Denmark , and a first cousin of the present Danish monarch , Queen Margrethe II .
Alexandra of Denmark (Alexandra Caroline Marie Charlotte Louise Julia; 1 December 1844 – 20 November 1925) was Queen of the United Kingdom and the British Dominions, and Empress of India, from 22 January 1901 to 6 May 1910 as the wife of King-Emperor Edward VII.
Caroline was born on 1 March 1683 at Ansbach, the daughter of John Frederick, Margrave of Brandenburg-Ansbach, and his second wife, Princess Eleonore Erdmuthe of Saxe-Eisenach.   Her father was the ruler of one of the smallest German states; he died of smallpox at the age of 32, when Caroline was three years old.
Princess Marina was born on 13 December 1906 in Athens, Greece, during the reign of her paternal grandfather, George I of Greece. She was the third and youngest daughter of Prince Nicholas of Greece and Denmark, and his wife Grand Duchess Elena Vladimirovna of Russia.
Princess Caroline was heiress presumptive to the crown of Monaco until the birth of her brother's legitimate children. There is precedent for a Monégasque prince to adopt his own illegitimate child and thereby place that child at the head of the line of succession to the Monegasque throne , as was done for Caroline's grandmother, Princess Charlotte, Duchess of Valentinois . 
Princess Caroline was born at Herrenhausen Palace in Hanover, Germany, on 10 June 1713 (New Style Gregorian calendar). Her father was George Augustus, Hereditary Prince of Hanover , the eldest son of George Louis, Elector of Hanover .

The youngest and posthumous daughter of Frederick, Prince of Wales , by Princess Augusta of Saxe-Gotha , Caroline Matilda was raised in a secluded family atmosphere away from the royal court.
