Louis I, Grand Duke of Hesse
In 1776, he became engaged to Sophie Dorothea of Württemberg, eldest daughter of Frederick II Eugene, Duke of Württemberg. The engagement was broken off so that Sophia Dorothea could marry Louis's recently widowed brother-in-law Tsarevich Paul Petrovich, son and heir of Catherine II "the Great", Empress of Russia. He received a monetary compensation when the engagement was broken.
Princess Sophie of Saxe-Weimar-Eisenach (1911–1988)
Though the passports were released, Sophie for unknown reasons revoked her acceptance and stated she could no longer attend the wedding at the last moment. Plans for the ceremony continued regardless, with Juliana getting married on 7 January 1937. Princess Sophie was replaced as bridemaid by Baroness von Heeckeren van Kell, one of Juliana's ladies-in-waiting.
