Well, as can be seen from my intro. in the "Introduce Yourself" thread, here goes :
[Mother's side] ---
Grandma was from Munich, Germany. Grandpa was from Leningrad, USSR. He met her at a difficult time (and fortunately in her hour of need! It almost sounds like a Hollywood movies, with the hero dashing to the rescue of a fair maiden!

).
Both of them never spoke much about their war years or their ordeals after that. I learnt all this through my mother. I was in awe of my Grandpa. He was this huge guy, would roll his own cigarettes (and one for his dog too!), was rather harsh at times. He amazed me with his strength and vigour at his advanced age (He was 90 when he passed away in 1990).
Grandma was, well, grandma. I miss them both very much.
I don't think they ever let my mother's life be affected by their experiences (or the enemity of their country).
[Father's side] ---
Grandpa was half turkish, half austrian. He came well before war and settled in India, as part of his family business. He married a local girl (Supposed to have been the hottest chick in the village!

Serious, that was how he used to describe my grandma!).
Nice mixed cocktail, eh?
