In spring 1757, in the contemporary history of the family, there were two Princesses of Schwarzenberg (both deceased) to refer to. To avoid potential misunderstanding, let’s review the persons involved one more time.
At the time of the narrative, the Schwarzenberg family comprised the incumbent prince (born 1722, only indirectly presented in the narrative) and his seven young children, of which the daughter Theresa is mentioned as Amalia’s friend and playmate. The mother of the children, born in 1721 as Princess Liechtenstein, had died several years prior to 1757 and as such does not belong to the narrative. However, she did bear the title of Princess Schwarzenberg during her lifetime, a fact that may potentially cause confusion, especially in the disorientating jungle of titles, branches and names of aristocracy. Yet the centre of the intrigue is not she but her mother-in-law Eleonora (1682-1741), born Princess Lobkowitz.
By now, the reader has likely realised that Madame Trautson is at cross purposes here and mistakenly talking about the wrong person. Her little fallacy will be cleared up in the forthcoming chapter.
