Hi
I am a relative of Bernard Wendlandt's second wife, Gertrud Winkelmann. I have an interest in finding out more about Bernard Wendlandt , and trying to trace/contact descendents from his daughter by second marriage, Helga (dec), who I believe settled in Victoria sometime after after WW2.  
It does sadden me to to learn on here that Wendlandt does not seem to have been 
a good father, after abandoning the children of his first mariage.
In the last few months I have been able to gather quite a lot of info about Bernard Wendlandt. if any one is interested I am happy to pass my info on, feel free to drop me a private message.
