Thijs,the visit of the King of Württemberg fueled rumours that his son-in-law Fritz of Wied,Marietjes son,would possibly be the future Heir to the Dutch Throne.Juliana was just 3 years,and Queen Wilhelmina had suffered several miscarriages.The visit included talks about Fritz's possibilities in it's framework.But that was highly frowned upon here,the dutch didn't wish/want any other House then the House of Orange.
They ditched the very idea.
On a personal level,the Wieds,specially Fritz and Pauline,were on very good terms with the dutch RF.
Once again,the pictures/images you provide are marvellous!
