GC winner data needed

[Mark Yerger]

Looking for any info on the following 6 Waffen-SS non-officer German Cross in Gold winners. I have their award date, unit at that time, and rank at that time. Need any other data to include birthdate, SS#, other career data, fate, etc.

Johann Brandstätter
Georg Erhard
Josef Gruber
Arnold Hansen
Otto Hoff
Franz Hörmann

Thanks
Mark
