Frances de la Tour episode.
Some interesting info, but didn't take to her personally. Think I was expecting her to be witty and laconic, but she was neither (IMHO).
Also found the beginning v.confusing - running through the tree that granddad had prepared at the speed of light, all those de la Tours/de latours/delatours/de la vals/delavels, change of name, etc. Quite made my head spin.
And on a general point, lots of these WDYTYA people are educated, but appear to know nothing about the past and how people lived. I don't just mean their own family history, I mean they know nothing of history, of illnesses, of social attitudes, of living conditions, of anything.
To me, Frances seemed to grasp the importance/significance of money, saying a couple of times, "Oh that would have been a large sum of money back then", but didn't really seem to understand the social ignominy attached to an unmarried woman, let alone that the woman was a minor aristocrat, having an illegitimate baby back in the late 1700s. I thought her "things were different back then" (or words to that effect) was just a way of passing it off without realising the true significance to the woman or, indeed, to the woman's family.
Not sure I've expressed this very well.
