Is it me, but is it a bit weird that folk have 'carried on' and thought no-one will ever know - and now it's possible that their actions may be potentially laid bare because of DNA evidence.

We all know how criminals are being caught decades after committing crimes because of advances in DNA science, but here we are talking about the man/woman-in-the-street having the means to discover the truth about long-lost family secrets.

Don't really know why I feel uncomfortable about this. I know my paternal great grandmother was immoral before she married, when she was married and after she was married. But I know this from the available records in newspapers and birth and census records. I don't feel anything about it - I just accept it as a fact of life, I suppose. Is there really any difference between having this knowledge from these sources and getting DNA matches? Logically not. But it feels different to me somehow.
