{{Dutch Royal Family}}
Van Vollenhoven married [[Princess Margriet of the Netherlands]] at [[The Hague]] on 10 January 1967, in the [[Grote or Sint-Jacobskerk (The Hague)|St. James Church]]. This made him the first member of the [[Dutch Royal House]] being a [[commoner]] and not of [[royal family|royal]] or [[nobility|noble]] origin. He was not given any royal titles as a result of the marriage and is therefore formally addressed as "Mister Van Vollenhoven" or by his professional title as "Professor Van Vollenhoven".

The couple went to live in [[Het Loo House]], near the [[Het Loo Palace]]. They have four sons:
*[[Prince Maurits of Orange-Nassau, van Vollenhoven]] (born 17 April 1968), married [[Princess Marilène of Orange-Nassau, van Vollenhoven-van den Broek|Marilène van den Broek]] (born 4 February 1970);
*[[Prince Bernhard of Orange-Nassau, van Vollenhoven]] (born 25 December 1969), married [[Princess Annette of Orange-Nassau, van Vollenhoven-Sekrève|Annette Sekrève]] (born 18 April 1972);
*[[Prince Pieter-Christiaan of Orange-Nassau, van Vollenhoven]] (born 22 March 1972), married [[Princess Anita of Orange-Nassau, van Vollenhoven-van Eijk|Anita van Eijk]] (born 27 October 1969);
*[[Prince Floris of Orange-Nassau, van Vollenhoven]] (born 10 April 1975), married [[Princess Aimée of Orange-Nassau, van Vollenhoven-Söhngen|Aimée Söhngen]] (born 19 October 1977).

The German house name [[Lippe-Biesterfeld]] is borne by the children of Prince Maurits (making them Van Lippe-Biesterfeld van Vollenhoven); his other (grand)children are just van Vollenhoven.
