Documentation that I have says he arrived in the United States from Austria under the name "Wasyl Zank" (in the early 1900s). He was born 25 Feb 1890 in Delejow, Austria. His marriage record says Wasyl Zajac, which is also mentioned in a written biography handed down via a family tree. He married Rose Kalyniuk.
He was later known as Charles, and on his Canadian naturalization papers it says "Charles Zank", which eventually became Zink (not sure how).
I am unable to find any information about his parents or even his birth town. It does not appear that Delejow, Austria exists anymore.
Any help is greatly appreciated, including general tips/info about slavic history.
