If it's Michele's father, he was in Bonn and not Siegburg. In the main camp of Stalag VI G in Bonn-Duisdorf about 7,000 of 53,000 prisoners of war who belonged to Stalag VI G, most of them in smaller camps as described somewhere above. The Camp in Bonn (and some others) is also mentioned in the Prioners Of War Bulletin od the American National Red Cross of Dec. 44 whichyou'll find here:
