Just how exactly were she and her husband (Duke Roberto of Parma) related, anyway? I know that he and his first wife (born Princess Maria Pia of the Two Sicilies) were close cousins, since both came from the same stock of Bourbons.

But the second wife had ancestry from German, morganaut, and mediatized houses, since her mother was Adelaide of Löwenstein-Wertheim-Rosenberg, and maternal grandmother was Princess Agnes of Hohenlohe-Langenburg.
