In Austen's Pride and Prejudice, the Bennets live in the real live, then-rural,  county of Hertfordshire on their imaginary estate of Longbourn. Mr.Bingley's equally fictional Netherfield Park is also here. 

"Upon my word I say no more here than I might say in any house in the neighbourhood, except Netherfield. He is not at all liked in Hertfordshire. Every body is disgusted with his pride. You will not find him more favourably spoken of by any one.”

"Mary had heard herself mentioned to Miss Bingley as the most accomplished girl in the neighbourhood; and Catherine and Lydia had been fortunate enough to be never without partners, which was all that they had yet learnt to care for at a ball. They returned, therefore, in good spirits to Longbourn, the village where they lived, and of which they were the principal inhabitants. They found Mr. Bennet still up."
