tbh, I'm not sure what "secrets" I have discovered.. Pretty much everything was unknown.
My grandfather had a brother and sister that died young we never knew about.
I *suspect* that his grandparents may not have been legally married, but there's always the possibility that a certificate may turn up with some mangled spelling.
I think the most horrible things I've discovered are when people end up in the workhouse, and dying there, whilst still "in the prime of life" because of widowhood, abandonment or illness'
There was talk, at a recent family funeral of the legend of a murder, but sadly it was the deceased person who had known the story and no-one else did
