Benigna Gottliebe von Trotta genannt Treyden

When Anna became Empress of Russia in 1730, the Biron couple both followed her to Russia, retaining their position as adviser and lady in waiting. Benigna is described as haughty and bad tempered and marked with smallpox, but also as a diligent parent and lady in waiting. She spent great amounts of money on clothes and jewelry and also received many costly gifts from Anna.

When her husband was made duke of Courland in 1737, she was decorated with the Order of Saint Catherine. She shared her husband's imprisonment in 1740 and returned with him to Courland in 1763, where she spent the rest of her life at the court in Mitau (Jelgava).

She is described as a good painter and textile artist, and she and her daughter embroidered a tapestry of silk which were displayed in the Jelgava Palace. She also published a book of religious German language poems, published in Moscow in 1777 entitled "Eine große Kreuzträgerin".
