Mmmmmm... but a lot of these 'different' ancestors will be the same people i.e. when cousins, second cousins etc marry each other. I don't think if you went back down MY family tree (being as it's mostly Scots and Irish) you'd have much chance of coming across William the Conqueror nor any of the Stewarts either. In addition, of course a lot of people aren't indigenous. Remember Boris Johnson and his Turkish ancestry or David Baddiel and his German/ Jewish forebears? Finally, of course, a lot of us are going to find out that our research runs out of steam somewhere in the 18th century and that what came before that will forever be a mystery, so when someone CAN trace their family back to 1066 it is at least a bit interesting. I like the programme, and I have to say I liked the picture of Alexander Armstrong it showed us. He seemed like a genuinely nice guy and in complete contrast to some of the self-obsessed individuals we've seen in previous programmes.
