Life with Boswell:
Boswell was introduced to her at the court of Dessau on September 24, 1764. He danced with her, and with her two sisters, at a ball on September 29, held by the Princess Wilhelmine in honour of the deposed Duke of Courland.
On September 30, 1764 - the day of his taking leave of Dessau - he described the Princess as "a comely, black, amiable young lady."
