Queen Victoria, the British monarch from 1837 to 1901, and Prince Albert (her husband from 1840 until his death in 1861) had 9 children, 42 grandchildren, and 87 great-grandchildren.
Victoria and Albert had 22 granddaughters and 20 grandsons, of whom two (the youngest sons of Prince Alfred and Princess Helena) were stillborn, and two more (Prince Alexander John of Wales and Prince Harald of Schleswig-Holstein) died shortly after birth.
Their first grandchild was the future German Emperor Wilhelm II, who was born to their eldest child, Princess Victoria, on 27 January 1859; the youngest was Prince Maurice of Battenberg, born on 3 October 1891 to Princess Beatrice (1857–1944), who was herself the last child born to Victoria and Albert and the last child to die. The last of Victoria and Albert's grandchildren to die (almost exactly 80 years after Queen Victoria herself) was Princess Alice, Countess of Athlone (25 February 1883 – 3 January 1981).
Just as Victoria and Albert shared one grandfather (Duke Francis of Saxe-Coburg-Saalfeld) and one grandmother (Countess Augusta Reuss), two pairs of their grandchildren married each other:
In 1888, Princess Irene of Hesse and by Rhine, whose mother was Queen Victoria's daughter Alice, married Prince Henry of Prussia, son of Victoria's daughter Victoria.
Another of Alice's children, Grand Duke Ernest Louis of Hesse, married Princess Victoria Melita, daughter of Alice's brother Alfred, Duke of Saxe-Coburg and Gotha, in 1894, but divorced in 1901.
Prince Albert, the Prince Consort (26 August 1819 – 14 December 1861), lived long enough to see only one of his children married (Victoria, the Princess Royal) and two of his grandchildren born (Wilhelm II, 1859–1941, and his sister Princess Charlotte of Prussia, 1860–1919), while Queen Victoria (24 May 1819 – 22 January 1901) lived long enough to see not only all her grandchildren, but many of her 87 great-grandchildren as well. (Three of Victoria's 56 great-grandsons were stillborn, another died shortly after birth, and one of her 31 great-granddaughters was born out of wedlock.
