I'm just cooking dinner so I'll come back later but, quickly, when I was a kid I loved to be around all the grown-ups talking on their rare family get togethers (ie. Christmas, the summer picnic, and weddings).
My paternal Grandad was a bit of a Delboy character by all accounts. He was from Wiltshire but married and had a family in South London long before South London was a desirable place to live. He was a motor mechanic among other things, when cars and vans were a rarity. He operated on the wrong side of the law a lot of the time and got away with it by being incredibly charming. My lower middle class mother always said you'd shake his filthy oily hand just because he made you feel you wanted to.
Any more interesting family folklore from years back?
