Prince Wilhelm Friedrich Franz Joseph Christian Olaf of Prussia (4 July 1906 – 26 May 1940) was the eldest child of Wilhelm, German Crown Prince, and Duchess Cecilie of Mecklenburg-Schwerin.

Prince Francis Frederick Sigismund of Prussia (German: Franz Friedrich Sigismund; 15 September 1864 – 18 June 1866) was the fourth child and third son of Crown Prince Frederick William of Prussia (later King of Prussia and German Emperor as Frederick III), and Victoria, Princess Royal, eldest daughter of the British Queen Victoria.
Prince Eitel Friedrich was born on 7 July 1883 as the second son of the then Prince Wilhelm of Prussia, and his first wife, Princess Augusta Victoria of Schleswig-Holstein.

Prussia now stretched uninterrupted from the Niemen in the east to the Elbe in the west, and possessed a chain of disconnected territories west of the Elbe.
