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:
Philippe I, Duke of Orléans
The couple moved from the Tuileries in early 1662 to the Palais Royal. Later in March of the same year, Philippe became a father when Henrietta gave birth to their daughter Marie Louise, the future wife of Charles II of Spain. Henrietta's disappointment at the birth of a daughter was great, and she even remarked that she should "throw her into the river!" This greatly offended Queen Anne, who adored her first granddaughter. For his part, Philippe would always consider Marie Louise his favourite child. The girl was baptised on 21 May 1662. On the same day Philippe took part in the famous "Carrousel du Louvre", where he dressed extravagantly as the King of Persia with the king as the King of the Romans and all ladies of the court in attendance.
