Dunno, mate. I'm quoting the Daily Torygraph. How far back do you have to get to have a hundred ancestors. Wait a minute. Go back to 60 That is 2+4+8+16+32. Great-great-great grandparents and their descendants. Three were white. Six were chinese. And the remaining fifty-odd were black. I think if you mess about with a tree diagram it'll come right.
