I've enjoyed most of this series, but I particularly liked last night's one. I like the way that the style of the show seems to have changed to concentrating on finding one or two interesting people and then going with them, and finding out as much as possible, rather than just plodding through a chain of people.
I was particularly jealous of the amount of records and references that they managed to dig out for Sarah Millican's ancestors, and must admit to welling up with her when she read the bit about her diver ancestor and the orphaned children. And as for her poor Scottish ggggrandfather who had to have his feet chopped off! Aargh! But they did kind of gloss over the fact that she already knew that he had had a happy ending, because she had seen the tree before she went, so knew that he had descendants. (Though maybe they didn't show her the dates, so she wouldn't have been sure if he married before or after his Canadian adventure).
