there is a town called Uniatycze in western Ukraine Polonius
Uniatycki / Konopska or Konopski / Chec ? Thanks.
these people could have been equally Polish or Jewish
while cki/ski surnames are typically Polish many Jews accepted surnames of the noblemen they used to work for in the late 18th an early 19th century (they worked in various roles for the noblemen but were free people)
