Using a nom-de-plume, the Marquise de Fontenoy, the American writer, Marguerite Cunliffe-Owen, wrote a gossip column that was published in American newspapers, including the Washington Post. Her article about the death of Duchess Pauline includes a tidbit that I had not noticed before:
She "had lived to a great extent in Italy, since a few years ago, she contracted a morganatic marriage with her chamberlain." She continued to be styled as grand duchess, "only by courtesy, and it is not probable that she will be mourned to any extent by her son's dominions, for she was quite the reverse of popular." According the marquise, Pauline "contributed even from a distance, to create the difficulties which rendered the position of her daughter-in-law, the present grand duchess, so extremely difficult during the first few months of marriage."
Pauline was "extraordinarily fat, and one of the most plain-featured princesses of Germany, her homeliness being of the crabbed and sour order rather than of a genial nature."
The morganatic marriage did not appear in the Almanach de Gotha, and had not been approved her Pauline's son, the Grand Duke of Saxe-Weimar. Thus, the marriage was not sanctioned by the Saxe-Weimar government.
The article did not mention the name of the chamberlain.
