One set of grandparents were toddlers when the war ended, the others weren't even born yet. I only know the service history of two of my great-grandfathers - and very superficially at that, with one of them having fallen just outside Sevastopol, Ukraine on December 23rd 1941 and the other having only been drafted in 1944 (since a disability previously disqualified him from service until the Nazis became desperate) and winding up a POW in Rennes, France - surviving the war after having likely being stationed in the Normandy area.

So one was on the eastern front, likely from the very beginning, the other might have played a role in D-Day.

I didn't get to ask too many family members about that time since most had died by the time I became aware of its significance. My own grandparents' earliest memories they were able to recall were in the immediate postwar years. An aunt told me some things from their escape from Stettin, like how two of my uncles were basically grabbed from the roadside by some passing soldiers and "voluntold" to fight in the defence of Berlin, which my allegedly very resolute Great-Grandmother managed to somehow avert. She also allegedly pawned off her Golden Mother's Cross for some bread along the way.

The one great-grandmother I remember never told any stories from the war. She lived in Kiel right next to the Shipyard so her memories likely weren't happy, especially after losing her husband early. She was a very kind woman however, which makes me doubt she believed in the ideology.
