Good observation; it seems to match my impression the Morlands in NA2 are portrayed as farmers.
In the early christening scene, a clergyman christens baby Catherine with her parents side by side. Mr Morland appears dressed as a farmer not a clergyman.
I think in NA2 the Morlands are made poorer than they are in the canon- similar to 'poor Bennets' in P&P3.
Catherine is no heiress but her dowry of £3,000 is quite good,compared to some JA heroines, she was no pauper.
John Thorpe never appears to speak in moderates ! As an attention seeker or trying to impress Catherine or Gen. Tilney- he's always exaggerating, blustering or flambulates (now what was Tim Lee's term ?).
Among John's last reported words by JA, I think these show him up;
'They were in fact a necessitous family; numerous too almost beyond example, by no means respected in their own neighbourhood...aiming at a style of life which their fortune could not warrant; seeking to better themselves by wealthy connections; a forward, bragging race.'
Here, instead of describing the Morlands, I think John sums up his own family, the Thorpes. ;)
I am presuming the dowries of the Morland girls Mr Morland's 'considerable independence'.
I wonder what that is ? In her hopes of a good marriage settlement from Mr Morland for herself and James, I wonder if Isabella Thorpe was thinking about
Mr Morland's 'considerable independence'?
