I think the Countess Maria Beatrix von and zu Arco-Zinneberg was on the B-list and was photographed together with her brother Prince Lorenz of Belgium, Archduke of Austria-Este, when they left the event. This means: after the A-list and the B-list mingled together (when both diners were finished).
Prince Lorenz was on the A-list, being married to Princess Astrid of Belgium, a cousine to the Grand Duke.
The fact that Maria Beatrix was photographed gives hopes for pictures of Princess Sophie of Prussia and the Duchess of Parma.
