About Prince Christopher of Greece and Denmark
Prince Christopher of Greece and Denmark (Greek: Χριστόφορος, romanized: Christóphoros; 10 August 1888 – 21 January 1940) was the fifth and youngest son and youngest child of King George I of Greece, belonging to a dynasty which mounted and lost the throne of Greece several times during his lifetime. Much of his life was spent living abroad. == Family background == Christopher was born at Pavlovsk, Imperial Russia, son of King George I of Greece and Queen Olga, a Russian grand duchess by birth. He was the youngest of their eight children, being twenty years younger than their oldest child, Constantine. He was called "Christo" in the family. His older brothers were future King Constantine I, George, Nicholas and Andrew. Christopher, like his siblings, was a polyglot, speaking Greek, English, Danish, Russian, French, and Italian. The siblings spoke Greek to one another, and used English with their parents. The parents, however, spoke German to each other. The Greek royal family maintained close relations with the Danish royal family, to which they also officially belonged.
