Prince Carlos, Duke of Parma
Prince Carlos had a relationship with Brigitte Klynstra (born 10 January 1959), the stepdaughter of Count Adolph "Roderik" van Rechteren Limpurg. During this relationship he fathered a son:In December 2015, the then 18-year-old Carlos Klynstra started the legal procedure to attempt to change his surname to that of his biological father which would also allow him to use the title of "Prince". The Duke of Parma opposed this on the basis that it was in contravention of the traditions of the House of Bourbon-Parma. On 9 March 2016 the Minister of Security and Justice declared his family name request valid. Later that year a court in The Hague concurred with the minister in declaring the claim valid under Dutch law.
