There is a village called ????? RUS, that can be loosely transliterated as Weseje (Veseja would be closer to the original pronounciation) close by. If they did not have a church in the village, children would be baptised in the town several miles away.
It is in Russian, but you can find the ????? village just north east of the town.
Looking at their phonebook at http://www.telpoisk.com/belarus-minsk-slutsk/#http://www.telpoisk.com/belarus-minsk-slutsk/# RUS, there is a bunch of people who's surname is ?????? RUS or ?????? BLR. This correponds to any of the English spellings you give. It is not a very common surname in Belarus, so given that the village in question appears tiny, with great likelihood these guys are your relatives.
Here are phones and addresses for some ??????'s in ?????:
