[2] She was born on 31 October 1604 as the youngest child of Pál Nyáry, the castellan of Várad (Nagyvárad; today: Oradea, Romania), Ispán (Count; comes) of Bihar and Közép-Szolnok Counties.

They had two daughters: Count Imre died suddenly in 1621, and as a result, the House of Thurzó became extinct in the male line.

The widow, promising a rich heritage, married Count Nikolaus (Miklós) Esterházy (1583–1645) in Szucsány (today: Sučany, Slovakia) on 21 July 1624.

The marriage produced the following children: The family's court chaplain was the Jesuit Mátyás (Matthias) Hajnal, who recommended his devotional book of Jesus' Heart, published in Vienna, 1629, to Krisztina Nyáry.

That work is a precious memorial of the beginning of the Hungarian Baroque literature.
