Associated with Koskowski family was Miłosz Kotarbiński, a man of high personal culture, painter, co-organizer and later the director of the School of Fine Arts in Warsaw (later ASP).
In the eighties of the nineteenth century Kotarbiński met his future wife, Ewa Koskowska. Around 1885 the painter's father moved from Czemierniki to Chrzęsne, where he was appointed an administrator of the estate. Ewa - a beautiful, dark-haired owners' daughter, a "capable pianist playing with great sensitivity romantic musicians" certainly was touched by good manners and artistic culture, as well as better and better position of the painter. Also their passion for music might have had an important role, as also Milosz since his childhood showed interest in music. In effect - as friends say, the painter "found himself a wife through singing".
It is not exactly known whether Ewa - like her sisters - received from parents any demesne. The Kotarbińskis after the marriage lived in Warsaw. Summer months, Miłosz Kotarbiński with his wife Eve nee Koskowski spent in Chrzęsne. According to the account of Adam Kotarbiński (grandson of Miłosz and Ewa Kotarbiński), his grandparents, staying in Chrzęsne, lived in the so-called "kantorek" forest cottage in the defunct forest near the palace. The mark of those days remains in "Children in the garden", the painting of Władysław Podkowiński on which the painter depicted sons of Ewa and Miłosz Kotarbiński.
Two children characters portrayed by Władysław Podkowiński have become extremely important for Polish science and culture, later as adults. Older one, then six-year old (with a watering can) is Tadeusz Kotarbiński, later world-renowned philosopher and scholar. The smaller boy is Mieczysław Kotarbiński, the future visual artist, creator of, among others, Józef Piłsudski marshal's baton.
