Not sure of Spelling
My grandmother was a Rozak, Rozack, Rosak, Rosack ...
OR maybe the immigration people could not spell or understand the alphabet.
It could have looked like an R but actually, pronounced with a K.
On one document my cousin and I looked at one night might have been Kupiac or some derivative of that.
Born in Ukraine (Galiceia, Austria) is on official papers.
Moved to Canada around Winnepeg, Manitoba and then to IL around St. Louis, MO.
