London: London of course plays a huge role in many of the novels, as it should since it is so prominent. In Pride and Prejudice, Elizabeth’s (or Eliza, which also happens to be the name of Jane Austen’s cousin) aunt and uncle lived there.
Brighton: The town of Brighton is located in Sussex. Brighton is mentioned in the novel and movie adaptation, and in Lydia’s words, “That's the place to find husbands.” Lydia is taken there by some family friends, and then runs away with the perfidious Wickham. This is a problem since women of this time are not to go anywhere unchaperoned.
The Most Prominent Locations were Fictional: Even though it is stated in the book that the Bennet’s live in Longbourn, a town in Hertfordshire, Mr. Bingley’s home is Netherfield Park, and Mr. Darcy’s is Pemberley, none of these locations actually exist.
Oxford: Sisters Elinor and Marianne Dashwood go to Oxford in Sense and Sensibility to discretely scout out their love interests, Edward Ferrars and John Willoughby. However, they find Willoughby with his new fiancée, much to Marianne's dismay.
Devonshire: This is where they move to after the death of their father. They move into one of their uncles unused estates. (Now referred to as Devon, England)
Sussex: Due to the death of their father, Mrs. Dashwood, Elinor, Marianne, and Margaret are forced to leave the fictional Norland Park, and settle in the also fictional Barton Cottage, in Devonshire.
