Most were killed during the second world war but my parents and grandparents had the foresight to leave when my father was demoted from being manager of a factory to sweeping the floors.
They then left luckily, before the war actually started.
Well, it all depends on what you mean by ancestors.... I'm British which means I am a mongrel mix up of many different races.
My dad's family came from the very north of Scotland before moving to London and he is clearly descended from Vikings - and oddly this was confirmed by a professor in Belgium who was researching a medical condition I have and had a theory that it only affected those with Viking genes.
My mum appears to be from more solid Norman/Saxon stock but also has Scottish family a few generations back in the family tree, so some Celtic genes must be in the mix as well.
But those are all hundreds of years ago. We did recently discover that a grandmother of my father's that we had always believed to be Scottish was actually Manx but otherwise we're either Scots or English.
