King George V of the United Kingdom (1865 – 1936)

(All photos credits – Wikipedia unless otherwise noted)

King George V of the United Kingdom was born on June 3, 1865, a month early, at Marlborough House in London, England. He was the second son and the second of the six children of King Edward VII and his wife Alexandra of Denmark, who were the Prince and Princess of Wales at that time. Queen Victoria of the United Kingdom and Prince Albert of Saxe-Coburg and Gotha were George’s paternal grandparents. His maternal grandparents were King Christian IX of Denmark and Princess Louise of Hesse-Kassel. George’s elder brother Prince Albert Victor, Duke of Clarence, known as Eddy, was expected to become king. However, Eddy died of pneumonia at the age of 28 and George became second in the line of succession after his father. George married Princess Victoria Mary of Teck, his deceased brother’s fiancee, and had five sons and one daughter.

The children and grandchildren of George’s paternal grandmother Queen Victoria married into other European royal families giving Victoria the unofficial title of “Grandmother of Europe.” Her grandchildren sat upon the thrones of Germany/Prussia, Greece, Norway, Romania, Russia, Spain, and the United Kingdom as monarchs or consorts. Similarly, George’s paternal grandfather King Christian IX of Denmark can be called the “Grandfather of Europe. His grandsons were the monarchs of Denmark, Greece, Norway, Russia, and the United Kingdom.

King George V had 34 paternal first cousins and 33 maternal first cousins for a total of 67 first cousins.  He shares his first cousins with his siblings Prince Albert Victor, Duke of Clarence; Princess Louise, Princess Royal, Duchess of Fife; Princess Victoria; Princess Maud, Queen of Norway; and Prince Alexander John.

Because King George V has so many cousins and because Unofficial Royalty has articles on all of Queen Victoria’s children, grandchildren, and their spouses and on all of King Christian IX’s children and many of his grandchildren and Wikipedia has articles on the others, this article will be a list on the cousins, with some information and an Unofficial Royalty link or a Wikipedia link where more information can be found.
