In the Netherlands the dynastic name of the children of Wilhelmina and Hendrik was decided by law. A special law made that Juliana had the family-name of Orange-Nassau and the same law applied for her four daughters.
These days the family-name is stipulated in the special bill of consent that needs to pass the Estates-General for the dynast to remain in line of succession after marriage.
Are you sure the same law applied to Juliana also applied to her daughters? I seem to think the issue of the names and titles of her daughters had to also be addressed, implicitly recognizing that the titles descend through the male line.
Haphazardly and inconsistently so. A mess.
The legal surname of the children of prince Maurits is Van Lippe-Biesterfeld van Vollenhoven and the name of the children of his younger brothers is Van Vollenhoven. The four sons of Princes Margriet themselves however are Of Orange-Nassau's.
Surnames are one thing. House names are another. The latter are seldomly set by statute and are usually a matter of genealogy.
