Her marriage to the Duke of Chartres took place at the Palace of Versailles on 5 April 1769 in a ceremony which all of the princes du sang attended. The marriage contract was signed by all members of the royal family. Afterwards, Louis XV hosted a wedding supper which included the entire royal family. Mlle de Penthièvre brought to the already wealthy House of Orléans a dowry of six million livres, an annual income of 240,000 livres (later increased to 400,000), and the expectation of much more upon her father's death.[citation needed]
