Princess Juliane Henriette Ulrike of Saxe-Coburg-Saalfeld (Coburg, 23 September 1781 – Elfenau, near Bern, Switzerland, 15 August 1860), also known as Grand Duchess Anna Feodorovna of Russia (Russian: Анна Фёдоровна ), was a German princess of the ducal house of Saxe-Coburg-Saalfeld (after 1826, the house of Saxe-Coburg-Gotha) who became the wife of Grand Duke Konstantin Pavlovich of Russia.
The princess lived up to 1920
That is definitely incorrect because it says she lived from September 23, 1781 up to her death in August 15, 1860.
