The Brest-Belarus Group completed two research projects on behalf of members. Individual research requests --typically, ancestral names-- were gathered and submitted as a group to the Minsk branch of the State Archives of Belarus.
At the moment, you can see a few procedural details of each project and view the research requests for each project and contact information for the requestors:
The 2004 Research Project
The 2005 Research Project
