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.
Countess Palatine Dorothea Sophie of Neuburg
Her husband died on 6 September 1693, only a month after the death of their son. On 7 December 1696, Dorothea married Odoardo's half-brother, Francesco Farnese, who had become Duke of Parma when his father died in 1694.
