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 Baden
Sophie was married to Woldemar, Prince of Lippe (1824–1895) second son of Leopold II, Prince of Lippe (1796–1851) and Princess Emilie of Schwarzburg-Sondershausen (1800–1867) on 9 November 1858 in Karlsruhe. The marriage was childless, leading to a dispute that lasted two decades between the two lines of the House of Lippe to inherit the principality after the death of Woldemar, in 1895.
