Maybe it is Princess Margherita di Savoia-Aosta (see picture)?
The Princess married Archduke Robert of Austria-Este and got a number of children: - Maria Beatrix Countess von Arco-Zinneberg née Archduchess of Austria-Este - Prince Lorenz of Belgium, Archduke of Austria-Este - Archduke Gerhard of Austria-Este - Archduke Martin of Austria-Este - Isabella Countess Czarnocki-Luchesi née Archduchess of Austria-Este
