I suggest you contact a charity, The Together Plan, which aims to help Jews now in Belarus become self-sufficient. One of their projects is genealogy. They have the huge advantage of not only speaking the local languages, but understanding the machinations of Belarussian bureaucracy ...
The charity is based in the Uk and in Belarus, so is well aware of Western expectations, while having to function in an old school Communist regime that does not want to change. You never know whether someone in the community still living in Belarus remembers some of the people in the photos !
