Yup, the picture is of Freddy. I have no idea how the archiv came into possession of his photo album, nor when they got it. His son Adalbert was KIA in WWII, but he had three daughters that survived. It was Otto that married into the von Stauffenbergs. I presume he's some relation, but I haven't been able to establish what the connection might be. (There are two different lines of Freiherr von Berchem - one Prussian and one Bavarian. If I remember correctly, Otto was Bavarian.) As far as I know, he only had two brothers. Max, who was a Hauptmann a.D. in Bavarian FAR 8, and Hans who was KIA as a Leutnant in Hessian Leibgarde Regiment 115. ...and yes, I'm interested in whatever I might be able to dig up.
