Antoni Adamczuk was born in 1905 and lived with his wife Janina and their children in Ostrów-Kolonia (Lubelskie Province). In early 1941, an acquaintance of the Jewish Persiko family from the neighbouring village of Horodysko came to their house. They had escaped from German resettlement of the Jewish population. Antoni and his family took care of the fugitives who, after some time, moved across the eastern border. Bluma Persiko, the youngest daughter of the family, stayed with the Adamczuks, who hid her in the attic. Thanks to this, she managed to survive until liberation. During the war, the family also provided emergency help to Miriam Breiter, Josef Fogiel and Josef Szpul. Antoni died in 1967.
