HRH Duchess Viktoria Adelheid of Saxe-Coburg and Gotha n?e Princess of Schleswig-Holstein

Emperor Wilhelm II of Germany was married to his second cousin princess Augusta Victoria of Schleswig-Holstein-Sonderburg-Glucksburg. As Augusta's maternal grandmother Feodora of Hohenlohe-Langenburg (n?e Leiningen) was the uterine half-sister of Queen Victoria, who was Wilhelm's maternal grandmother.

Augusta Victoria was the eldest daughter of Friedrich VIII, Duke of Schleswig-Holstein (Schleswig-Holstein-Sonderburg-Augustenburg) and Princess Adelheid of Hohenlohe-Langenburg. Her younger sister Karoline Mathilde married Friedrich Ferdinand of Schleswig-Holstein-Sonderburg-Gl?cksburg (who became Duke of Schleswig-Holstein).
The fourth son of Wilhelm and AV prince August Wilhelm of Prussia married his cousin princess Alexandra Viktoria von Schleswig-Holstein-Sonderburg-Glucksburg. She was a daughter of Friedrich Ferdinand, Duke of Schleswig-Holstein and his wife Princess Karoline Mathilde of Schleswig-Holstein-Sonderburg-Augustenburg (so she is an older sister of the above discussed Karoline Mathilde). Their marriage apparently failed, according to rumours because of August Wilhem's homosexual tendencies. It has been said they never undertook a formal divorce due to the opposition of August Wilhelm's father, Kaiser Wilhelm II.
