Daria Fedorovna Tyutcheva (1834 - 1903) was the second daughter of the poet Fyodor Tyutchev and his first wife, Countess Eleonore von Bothmer.

[2] It is known that she was treated in a clinic for the mentally ill for nervous shock caused by her unrequited love for Emperor Alexander II.

Her sister Anna Tyutcheva mentions in her diary for 1858 painful seizures Daria suffered from, caused by gossip about her and the emperor.

After Alexander's marriage to Princess Ekaterina Dolgorukova, Daria fled the court and moved to her sister's in Moscow.

Before leaving, she wrote an impudent letter to the emperor, in which he thanked him for the mercy shown to her and the preservation of all marital privileges, but asked him to promise her that under the new conditions, she would not be placed in a position that offended her feelings for the memory of the late Empress.
