Then try your village names with these spellings: Bilmony and Subotniki
When it shows a search result for a village, you can click on the village name, and a very detailed map will appear. You then can click to zoom out. I did this , and can tell you that Bilmony is 20 kilometers southeast of Subotniki, and doing a search for Berezyna puts it east of there. They all appear to be in the same general vicinity.
I read somewhere that the maps displayed there are from the late 1920's - 1930
