In the book Willem-Alexander, van prins tot koning
by Jan Hoedeman and Remco Meijer is written that the three sons of Princess Beatrix and Prince Claus were carried into the church by their nanny, nurse Elisabeth Jacoba Swellengrebel.
Back in those days, only in 1967, a careful selection was made. Nurse Swellengrebel had good relations in the "better circles". The nurse was known via her mother Christine Catherine Swellengrebel née Royaards, daughter of Johan Sebastiaan Royaards, Mayor of Scherpenzeel and owner of Scherpenzeel House (picture
