"My parents grew up / met each other in care, so I didn't know too much about our family history"
"Turns out he was Russian, he was arrested as a political prisoner alongside his dad and brother. His dad died whilst in the concentration camp."
I'm sorry but this rather confuses me. Was it your dad, uncle and grandfather who were in a concentration camp?
Or was it your grandfather, his brother and your great grandfather?
As other posters have said, this really is not any reason to "wish I hadn't looked now" . Learning about the reality of our ancestor's lives helps to put their decisions or actions into a perspective that we might better understand.
As @Parcell rightly observes:
"So your grandfather wasn’t a bad person, just an abused one. I realise it’s a shock but you will come to terms with it as it explains a lot of stuff."
.
But I was really intrigued by what you said, especially if this is about your grandfather:
"...he was arrested as a political prisoner..."
"...I'm sad reading about the camp he was in..."
Was this in the 1930s at all? Or was it much later? If this was in the 1930s, would you mind sharing where this information comes from? Either openly or by DM?
For context, my brother-in-law's wife is Russian. She is in her late 40s.
Her family has a story that her paternal grandfather and his parents were arrested and sent to the Siberian gulags in the early 1930s.
His parents were reasonably wealthy farmers (in that they employed men and boys to work on the farm) living around 100 miles north of Moscow. Then in the early 1930s, the family were denounced as 'kulaks' and shipped off to a Siberian gulag.
His parents never returned but my brother-in-law's wife's grandfather managed to escape or, by some other means, otherwise managed to return shortly afterwards.He eventually married and ended his days keeping a couple of cows on a few acres of land to the north of Moscow in a small wooden house, one half of which the family lived in and the other half housed the cows and their hay etc.
Incidentally, it was through speaking to her family that I first came across the term 'perestroika' used in an everyday way - rebuilding the house to convert the cow barn - rather than the political connotation of the word (political reform movement in the late 1980s)
.
Sorry, I was going totally off tangent there. In summary, her grandfather and great grandparents were arrested as political prisoners in the early 1930s and sent to .
I haven't been able to trace anything at all about this part of their lives. If the concentration camps that you speak of are anything at all related to the Gulags in Siberia in the 1930s then I really would welcome any hints or pointers at all.
