I'd seen this on the programme guide on my telly, but assumed it was a repeat (I can't remember seeing any trails for it), but set it to record anyway. It was only when I was looking at twitter during while the programme was on, and saw Ancestry and FindMyPast tweeting lots about the episode that I realised it was a new series.
I'm glad I had set it to record, as this was a really interesting programme. It was a little confusing in places, largely because the story it was telling was complicated. One thing that particularly confused me at the beginning was the age of his father: as someone has already said above, usually when we're looking at the 1901 and 1911 censuses, the only people (at best) whom we might have known and met are our grandparents. So it was a little difficult to get my head round the idea that it might actually be his father (early on in that bit of the programme, I was expecting an expert to leap out with evidence that Walter Dance wasn't actually his father!) He must have been a very well preserved chap to have got away with passing himself off as 50 when he was actually 75!
I couldn't work out (maybe I wasn't paying enough attention), whether the postcard of the Marylebone High St shop, was actually his ancestor's shop, and whether the interior of the modern shop was the original interior from that time, or pure chance that it's been restored like what the shop might have looked like. (If you see what I mean.)
What a treasure trove that trunk in South Africa was! But a bit bizarre when his great niece took one of the photographs of his father out of an album, and said he could have it. Presumably that bit was just for TV as I'd hope someone from the production company would have said they'd be able to copy it.
