let's hope Dr. Killius can provide you with a helpful contact. But don't expect too much. In summer 1944 about 2400 German women were working in Minsk for various organizations (Mühlenberg, 2011, p.298). So not anyone can have known anybody else.
Have you already tried Dr. Franka Maubach from the University of Göttingen? (http://www.generationengeschichte.uni-g ... aubach.php
) She wrote her Ph.D. thesis about Wehrmachtshelferinnen
and did interviews with a number of them. Perhaps she has some contacts that are useful in your case.
