Tomasz, Records from 1860 are likely to be in Grodno (try www.archives.gov.by/eng/) and information is on there how to apply for records. There are two Prudy settlements, colony and village. I have the following list of residents from 1937 for one of those settlements; perhaps the information you seek is among these: Zujewicz Pelagia Zujewicz Ignacy Zujewicz Jan Blaszkiewicz Maria,Eudokia Adamkiewicz Adamkiewicz Ignacy Zurawska Elżbieta Blaszkiewicz Michał Golowacz Jan Kozlowski Gerasim Kozlowski Michał Kozlowski Aleksy Zurawski Konstanty Zurawski Dymitr
