Do you know what happened to the Volkspark ? At the end of the war the Control Commission built an estate of posh houses for themselves on it. Later it was handed over to the RAF (and other services ?) as a village of OMQs - we had everything there to hand. Lived there a few months at end of 1960, then got a quarter at Geilenkirkchen.
Does "Grossrotterveg" or "Hitzler Strasse" help ?
