I'm also a bit wary of the idea of her having a child at the age of 48. I've been having a look on the internet, and of the more credible web sites, the consensus seems to be that a woman is very unlikely to conceive by natural means (i.e. without IVF or hormone treatment or other medical interventions) after the age of 45.
I've known (and known of) a number of women get pregnant during menopause, so that didn't seem immediately unlikely to me.
The Elizabeth/Bethia switch - I agree it's a bit of a trap, especially as I'm dubious already because of the parents. If I could only identify who first connected this particular Elizabeth/Bethia to my Robert... They might have had actual evidence!
I'd already started collecting Marshalls for elimination purposes. I foresee crazed diagrams in my future
