For the estimated 700 children conceived by [Wehrmacht] soldiers from 1940 to 1946, the situation was more challenging. The [Axis] had lost and German people found themselves very unpopular. This reflected on their soldiers’ children abroad and manifested in taunts and alienation by native Finns. A few dozen were named after their fathers but the resulting torment harassment quickly led to renaming the children with Finnish names. Their mothers, however, were stigmatised for the rest of their lives and hence frequently treated like second‐class citizens.
