When I first read your question I thought a connection improbable; after some reflection & googling that changed!
The Wikipedia page on #JaneAusten was helpful, & thinking about the conversational & subscription networks of a force of nature like #JohnNichols - Jane's father & #WarrenHastings might well have been typical of the customers in this age of gentleman #bibliophiles and #antiquarians?
