Two classic moments from watching that last night --
1/ Sarah Millican's in Orkney, tracking down a great (x 4) grandfather. He was a servant in the Hudson's Bay Company, in early 1800s. "So, is that in Orkney then?"
2/ Same g gg grandfather has signed up with above HBC and is in the Canadian wilderness, in winter. Doesn't sound like bundle of laughs, and things seem to go downhill swiftly. "Oh, I do hope it all works out well and he survives OK" is the gist of the comment. Of course he does, he's your direct ancestor!!!
