A vereniging (nl) is a type of legally-constituted organisation defined in Dutch law, with similar legal rights and responsibilities to other such types of associations and companies, but with its own kind of internal structure, which allows membership both of individuals and of corporate bodies.
It has been said that Marot was named after a French resistance fighter who had that name or who had used it as a nom de guerre.[7] If so, that person is not easy to identify.
