What an interesting and very honest thread this is, thank you for sharing your stories.
I think it does show that, especially now, things are easy to uncover and people are easier to find. I don't suppose that 50 or so years ago people ever dreamt that their lives would be so easy to unravel and incidents they thought they had hidden would come to light.
What we now do with this knowledge is another thing. I feel that it is in the past, it is history and whatever we do or feel can't change it. We shouldn't let it spoil our lives or our future. We need to accept that our ancestors probably did what they did for a reason, perhaps guilt, perhaps to protect those they loved or maybe to protect themselves. Their actions don't reflect on us, we had no part in it and people don't judge us by what our forebearers did.
