I've spent some time getting half of my family tree (my Mum plus the preceding 5 generations, going back to around 1800) written up. I'm very pleased with it, and although it wasn't quite finished, I took it along to a family gathering where people were really interested to look at it.
I've also taken it to a couple of craft events where it certainly generated plenty of conversation.
Sadly I've not discovered any rogues in my family yet - but I'll keep looking! The funniest thing about this tree is that I accidentally wrote my sister in law's date of birth as 1868 - she doesn't look nearly that old!
(And luckily it was quite an easy correction to make)
