I have two Kost Screpneks in my tree. One was an older brother of Moses who came over with Moses in 1900. He was born 1 May 1875 at Drachenetz, Bukovina. He was married to Doris Petraschuck.
The other Kost was a son of Moses born around 1921 in Manitoba, he moved to the Peace country in northern Alberta as a young boy. He was ordained as a Baptist Minister at Reno Alberta. He was married to Victoria Rpako. I don't know anymore about him.
