'It was an unsuitable connection and it did not produce much happiness.' Ch.2
Yes, but JA use the term 'connection' elsewhere in her works ? :)

My impression is if Miss Churchill's family had accepted Mr Weston easily; she would've been happier, more able to appreciate Capt. Weston as a husband while enjoying her position as a Churchill of Enscombe.
As speculation, if Capt. Weston had been of landed genteel family like Mr Knightley, they may've more readily accepted the match.
The Churchills 'full of pride and importance' appear to reinforce ideas of social structure. Yet the marriage of Capt. Weston maybe an example of social mobility through marriage.
As 'Emma' presents different social classes; I still wonder if the 'unsuitablity' of the marriage of Capt. Weston and Miss Churchill is more complex than personalities of the Churchills and Capt. Weston.

I should've referred to the term 'connection' in my first post.
However, the narrator also uses the term of match- Captain Weston, who had been considered especially by the Churchills, as making such an amazing match.'
