Not strictly DV related but I worked with a SNCO who had Hungarian parents (escaped during the 56 uprising).
When he did his interviews at the Careers Office prior to joining he was asked the standard question about previous family military service:
Q: So were any of you parents in the military?
A: My Dad and Grandad were both in the Army.
Q: What regiments?
A: Don't know, but my Dad was with the Russians and Grandad was with the Germans.
(Father had done NS pre 56 and Grandad had fought on the Eastern Front).
