I have found two more databases that list names of Russian-Germans conscripted into the labor army during World War II. The first is a list of 7,353 names from Tagilag. The second is a list of 20,711 names from Bogoslovlag. You have to enter the information of the person you are looking to find and the sites are in Russian. Earlier I posted a database for Usol'lag. I still have not found a database for Solikamlag.
