Attempting to research names Koszlak/Koslak/Kozlak and Benzik/Bendziuk from Nowosiolka or Podhajce, Ternopil.
great-great grandparents were Daniel (Danylo?) Koszlak (born 22 Nov 1890) and Anny Benzik (born 1891?).
Daniel immigrated to Canada aboard the SS Cassandra in 1910 and settled in Beausejour, Manitoba, Canada. He and Anny and 2 of their sons appear on the 1916 Canadian census of the prairies as Greek Catholic Ruthenians.
Daniel might have had siblings: Harry or Hawrylo Koszlak (lots of records on ancestry.com) who's wife was Katarzyna, then Hrynko, Jakob, George, and a sister Mary. I think many of these people lived in Minneapolis, Minnesota. But so far I have no found a record confirming a relation.
Canadian and American records are easily found on ancestry, looking for some Ukrainian information.
