Prince Nicholas was the third son of King George I and Olga, Queen of Greece. His older brothers were Constantine I of Greece and Prince George of Greece. His younger brother was Prince Andrew of Greece and Denmark, father of Prince Philip, Duke of Edinburgh.

Helen Vladimirovna was a daughter of Grand Duke Vladimir Alexandrovich of Russia (22 April 1847 — 17 February 1909) and Marie Alexandrine Elisabeth Eleonore von Mecklenburg-Schwerin.

Prince Alexander of Yugoslavia

Prince Nikola of Yugoslavia

Princess Elisabeth of Yugoslavia

Diminished status

Yugoslavia became a republic in 1945, and the Yugoslav Royal Family went into exile, Paul and Olga settling in South Africa. Greece became a republic in 1975 and stopped recognizing royal titles in Greek citizens. Olga's Yugoslavian and Greek titles were thus of questionable validity in those respective nations, but her Danish title remained valid, and she continued to be known as Princess Olga until her death.
