Agafya Grushetskaya
She was a daughter of (voivode, and boyar) Semyon Fyodorovich Grushetsky (Gruszecki) and his spouse, Maria Ivanovna Zaborovska.She could play the harpsichord, speak and write Polish, French, and Latin, and was well informed about the Western European life style; overall, she was a well-educated person.Aware that her uncle did not wish her to marry, a traditional summon was proclaimed to all unmarried noble women to gather for Feodor to choose from, and he chose her.Her husband's relative Ivan Iljitj Miloslavskii exposed her to slander, which caused a conflict, and was punished by Feodor.[2] On 11 July 1681, the Tsarina gave birth to her son, Tsarevich Ilya Fyodorovich, the expected heir to the throne.
