Together with her husband count Vladimir Zubov, she established and maintained six primary schools for children of manor workers and peasants in their estates near Šiauliai.

[5] Her father Hipolit Billewicz (Ipolitas Bilevičius) received a degree in philosophy and published in 1901 a philosophical treaty: Dumanie o Bogu i przeznaczeniu człowieka ("Wondering about God and the destiny of man").

[2][6] He took her on his trips to western Europe, but she spent most of her childhood in a rural manor in present-day Tauragė District Municipality.

He implemented various innovations and imported quality seeds, animal breeds, and farming equipment from abroad.

[9] Zubovienė was interested in pedagogy[2] and Zubovs established and financed six primary schools around Šiauliai for children of manor workers and other peasants.

Zubovs invited Lithuanian teachers, including Jadvyga Juškytė, and paid them a generous salary.

It features pleasant vacation mood and light philosophical conversations, but there is an undercurrent of tension (perhaps because the guest cannot be trusted and the hosts are engaged in the smuggling of illegal Lithuanian publications).
