Henriette-Anne was Henrietta Maria's daughter. She went to her mother's homeland and married the Duc d'orleans who was gay. She negotiated the Treaty of Dover in which England switched from an alliance with the Protestant Dutch and Swedes to support Louis XIV in conquering some Dutch provinces. The treaty became public in 1830. Her daughter Marie Louise married Carlos II of Spain. She died when she was 26. Her Wikipedia article is here.
