The widow of Zdenek Lev Libštejnský of Kolovraty, lady Katerina, was an embodiment of a strong-willed, sparing, wise and well-frugal woman who managed to extricate the Sloup estate from its debts. After a year (in 1641), she got married for the second time to Jirí Petr Kokorovec of Kokorov, a member of an old Bohemian noble family, promoted to aristocracy in 1637 for its devotion to the Habsburgs’ catholic policy.

During her rein, Katerina was well known and cherished for her philanthropic deeds towards the locals, of which we have some records even in 1831. V. Christ. Rubesch, the first author of book on Sloup, writes the following story based on the stories told among Sloup locals:

Among the inhibitants of Sloup, a likely legend is told that it was this Katerina who lived in the so-called old château situated north of Einsiedlerstein and who as a widow gained the love of all the people by her very kind and amiable behaviour. It is still told about her love to the poor, children and to those who are in need. It is still remembered and cherished by the people these days that this countess blessed every shanty with her visit, having a distaff in her hand and forgetting therefore no one who needed her help, comfort and mitigation of the misery.

In 1679, Katerina Kokorovcová rendered Sloup of “maternal affection and love” to her son Ferdinand Hroznata, baron Kokorovec of Kokorov. The contract guaranteed funds for keeping an eternal light in the St. Catherine’s Church in Sloup, masses funds and Ferdinand Hroznata was obliged to build a fence around the cemetery in Sloup.

Nine years later, March 12, 1688, Katerina Kokorovcová made her will in the village of ¬lutice. She ordered to be burried in the St. Peter and St. Paul’s Church in ¬lutice, she named Ferdinand Hroznata as her heir and also bequeathed money to many churches – 100 gulden each to Franciscans of the Church of the Virgin Mary of the Snows, to Franciscans in Prague in New Town (Nové mesto), to the Capuchins in Prague in Hradcany, to the Capuchins in Litomerice, to the Capuchins in Zákupy and also to the Order of Mercy in Prague for caring for the sick, and 50 gulden each to the Carmelite Order in Chýše and to the Servite Order in Rabštejn. From the list of funded churches it is obvious that the countess gave her money and favor mainly to the offshoots of the Franciscans. On the May 5, 1690, already after her death, her testament was registered and entered into “desky zemské” (a book in which the property owners in the Kingdom of Bohemia are listed).
