The first child of Prince Constantijn and Princess Laurentien, their daughter Eloise (Eloise Sophie Beatrix Laurence Countess of Orange-Nassau, Jonkvrouw van Amsberg) was born on 8 June 2002. Their son Claus-Casimir (Claus-Casimir Bernhard Marius Max Count of Orange-Nassau, Jonkheer van Amsberg) was born on 21 March 2004.
