Rightly or wrongly, the two richly dressed ladies Squire Thornhill brought with him to dance at the Vicar's door reminded me somewhat of the Bingley sisters.
This was reinforced by their high talk of fashionable topics like pictures, taste, Shakespeare 'and the musical glasses'.
In Pride and Prejudice, Ch. 11 Lizzy is obliged to listen to the conversation of the Bingley sisters '...their powers of conversation were considerable. They could describe an entertainment with accuracy, relate an antedote with humour, an laugh at their acquintnce with spirit.'
JA's description of the Bingley sisters talk appears fashionable and worldy like that of Lady Blarney and Miss Caroline Skeggs.
Interestingly, the vicar regarded the ladies as coarse and unrefined yet his daughters saw them as 'accomplished' women.
And the Bingley sisters were not from a gentry family.
