Matskiv was born in Chodorów, Second Polish Republic (now Khodoriv, Ukraine).

[1] She took her first vows on 5 November 1940, and worked in her convent,[2] sewing clothes for the sisters and teaching others the skill.

[3] Even before the arrival of the Soviet Army to Lviv, she took vows before her spiritual director, Volodymyr Kovalyk [uk], that she would give up her life for the conversion of Russia and for the Catholic Church.

When Matskiv answered the door, expecting to see a priest who was supposed to celebrate the liturgy,[3] she was shot without warning and died.

Then a shot rang out and Sister Tarsykiia fell down dead.
