"Princess Victoria Louise of Prussia (Viktoria Luise; 13 September 1892 – 11 December 1980) was the only daughter and the last child of German Emperor Wilhelm II and Augusta Victoria of Schleswig-Holstein. She was a great-granddaughter of Queen Victoria through her father. Her 1913 wedding to Prince Ernest Augustus of Hanover was the largest gathering of reigning monarchs in Germany since German unification in 1871, and one of the last great social events of European royalty before the First World War began fourteen months later.
Shortly after the wedding, she became the Duchess of Brunswick by marriage. Through her daughter Frederica, Princess Victoria Louise was the maternal grandmother of Queen Sophia of Spain (mother of Felipe VI of Spain) and the former King Constantine II of Greece." - (en.wikipedia.org 30.01.2020)
