Catherine "Kitty" Bennetis the fourth Bennet sister, aged seventeen. She is portrayed as a less headstrong but equally silly shadow of Lydia.
Lydia Bennet is the youngest Bennet sister, aged fifteen when the novel begins. She is repeatedly described as frivolous and headstrong. Her main activity in life is socialising, especially flirting with the military officers stationed in the nearby town of Meryton. She dominates her older sister Kitty and is supported in the family by her mother. After she elopes with Wickham and he is paid to marry her, she shows no remorse for the embarrassment and possible harm (as this could have hurt the other sister's chances of marrying) that her actions caused for her family, but acts as if she has made a wonderful match of which her sisters should be jealous.
Charles Bingley is a young gentleman without an estate. His wealth was recent, and he is seeking a permanent home. He rents the Netherfield estate near Longbourn when the novel opens. Twenty-two years old at the start of the novel, handsome, good-natured, and wealthy, he is contrasted with his friend Darcy as being less clever but kinder and more charming and hence more popular in Meryton. He lacks resolve and is easily influenced by others.
Caroline Bingley is the snobbish sister of Charles Bingley. Clearly harbouring romantic intentions on Darcy herself, she views his growing attachment to Elizabeth Bennet with some jealousy, resulting in disdain and frequent verbal attempts to undermine Elizabeth and her society.
George Wickham is an old acquaintance of Darcy from childhood, and an officer in the militia unit stationed near Meryton. Superficially charming, he rapidly forms a friendship with Elizabeth Bennet, prompting remarks upon his suitability as a potential husband. He spreads numerous tales about the wrongs Darcy has done to him, colouring the popular perception of the other man in local society. It is eventually revealed that these tales are distortions, and that Darcy was the wronged man in their acquaintance.
William Collins, aged twenty-five, is Mr Bennet's clergyman cousin and, as Mr Bennet has no son, heir to his estate. Austen described him as "not a sensible man, and the deficiency of nature had been but little assisted by education or society." Collins boasts of his acquaintance with and advantageous patronage from Lady Catherine de Bourgh. Mr Bennet, Jane, and Elizabeth consider him pompous and lacking in common sense. Elizabeth's rejection of Collins' marriage proposal is welcomed by her father, regardless of the financial benefit to the family of such a match. Elizabeth is later somewhat distressed, although understanding, when her closest friend, Charlotte Lucas, consents to marry Collins out of her need for a settled position and to avoid the low status and lack of autonomy of an old maid.
