Which English county is the Bennet family associated with in 'Pride and Prejudice'?

The Bennet family in Pride and Prejudice is associated with Hertfordshire.

The family lives at Longbourn, their estate near the fictional town of Meryton in Hertfordshire, England. This is where Elizabeth Bennet, her four sisters, their parents, and nearby acquaintances are introduced, and where much of the novel’s early social activity takes place.

Hertfordshire also brings the Bennets into contact with Charles Bingley and Fitzwilliam Darcy after Bingley rents Netherfield Park. The local assembly, visits, dinners, and militia social scene create the setting for Jane and Bingley’s courtship and Elizabeth’s first impressions of Darcy.

The other options are connected to important locations but not the Bennet home county. Kent contains Rosings Park and Hunsford, while Derbyshire contains Darcy’s estate at Pemberley. Somerset is not the principal county associated with the Bennet family in the novel.
