Sorry, I probably can't help you with your search but my father John (Ivan) Tkachuk was also born in the Bukovina in 1921. My father died a few years ago in St. Catherines, Ont.,Canada. He immigrated to Canada in 1951, he left his family when he was 15yrs. old because of the poor economical situation. We would like to know if anyone knows anything about his brothers or sisters or of any living relatives. If you need more information pls. contact.
