Emmy Bonn-Leijens had two children: Walter, and a child who survived the war. Shortly after the war, the surviving child still succumbed due to the medical experiments which it had suffered from in concentration camp. A comprehensive biography of the Bonn-Leijens family can be found in F. Krauwert Die drei Eisheiligen.
This book contains, between other things, a moving farewell letter of Emmy Bonn-Leijens.
