Aside from the four boys who died as infants, Queen Victoria had survived seven of her grandchildren: Prince Sigismund of Prussia (1864–1866) died of meningitis. Prince Friedrich of Hesse and by Rhine (1870–1873), a haemophiliac, fell from his mother's bedroom window and bled to death a few hours later. Princess Marie of Hesse and by Rhine (1874–1878) died of diphtheria. Prince Waldemar of Prussia (1868–1879) also died of diphtheria. Prince Albert Victor, Duke of Clarence and Avondale (1864–1892) died of influenza. Prince Alfred, Hereditary Prince of Saxe-Coburg and Gotha (1874–1899) shot himself with a revolver and died soon afterward. Prince Christian Victor of Schleswig-Holstein (1867–1900) died of malaria while on active service in South Africa during the Boer War.
