So many dead ends.Even if Swirowo was a small village, it still would show up on http://igrek.amzp.pl/mapindex.php?cat=WIG100http://igrek.amzp.pl/mapindex.php?cat=WIG100 as that is pretty detail map. What about the church that Olga Alexandria was baptised?Is the church any more willing in providing you her church baptismal? I am sure you already considered about trying to get Anastasia's and Vasili's church marriage record or state marriage application. Yes, that was customary the man/husband would arrive first, find an employment, place to live and then send for his wife and children. Anything in a way of a draft registration form for Iwan?Maybe Iwan was born in Wilno.
