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.
Maria Sophie of Bavaria
On 8 January 1859 in Munich at the Allerheiligen-Hofkirche Maria Sophie was married by proxy and then again married in-person on 3 February 1859 in Bari to the Duke of Calabria, the eldest son of Ferdinand II of the Two Sicilies, King of Naples. Within the year, with the death of the king, her husband ascended to the throne as Francis II of the Two Sicilies, and Maria Sophie became queen of a realm that was shortly to be overwhelmed by the forces of Giuseppe Garibaldi and Piedmontese army.
