William I of Württemberg
On 24 January 1816, in Saint Petersburg, he married his first cousin, Grand Duchess Catherine Pavlovna of Russia (1788–1819), daughter of Emperor Paul I of Russia (1754–1801) and Princess Sophie Dorothea of Württemberg (1759–1828). The couple had two children:
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.
