I notice that we had a few of them in our tree...........when I was a kid that was really frowned upon but maybe more acceptable then.
We also had an ancestor that spent some time in "the House of Correction"..........naughty boy.
The distant grandparents appear to have liked to drink and some violence, then the G*father died and the G* mother stole some stuff to get by and changed her name as well (for ... reason). Their daughter got in with a married man and they had a knife fight with each other (and her 3 month old by some other guy) and the guy (distant G*father) got convicted for that. There was some family euphemism about this time, but I'm not sure they'd really heard the details.
Ohh, forgot to say a load of emigrants to oz which is probably not surprising given the number of miners in the family and the living conditions at the time.
Think the oldest we got was when I linked into the Vitty family who came from Yorkshire. Fairly unusual name and the records seem to go back to the 1600s. Apparently, even if you can trace/guess the records back that far, quite a lot were lost in the civil war.
