I'm actually trying to get information about a Stepan Shirko who went to USA for about 8 years and returned back expected timeframe is starting about 1913 till about 1922
He was born as child of Zachary Shirko in the year 1884 (at least to my knowledge)
It was told to me that he was visiting Konopelko brothers which immigrated earlier and most probably living around Chicago. Firstnames of those are not yet known and subject of research.
