She was born in St. Petersburg, and baptized on June 29, 1802 in the Simeonov Church in the presence of her maternal grandfather, Baron Ivan Ivanovich Mestmakher, who at the time was the Russian ambassador to Dresden, and Princess Maria Khilkova.

“My child,” she said, “do as you want, but before you is a bad example of Konstantin.”[8] Princess Khilkova threw herself at the feet of the empress, saying that there was never any assistance on her part to arouse the passion of the Grand Duke and, as proof, asked permission to leave her place.

The change in the favorable climate of Kharkiv to Saint Petersburg had a detrimental effect on the health of Praskovya, and she was constantly ill. At the beginning of 1843, her disease worsened.

The whole court came to say goodbye to the body, the emperor was the last just before the removal, and Grand Duke Mikhail Pavlovich was at the funeral service in St. Isaac's Cathedral.

[8] The body of Countess Hendrikova was taken to the Kharkiv estate of her husband in the village of Grafskoe, Volchansk district, and buried under St. Andrew's Church.
