Mary Bennet is the middle Bennet sister, aged around eighteen. The only plain one of the five, she strives to be the most accomplished. She spends most of her time reading and studying, but without understanding. Of the sisters, she thinks most highly of Mr. Collins.
Catherine (Kitty) Bennet is the fourth Bennet sister, aged seventeen. Portrayed as a less headstrong but equally frivolous shadow of Lydia.
Lydia Bennet is the youngest Bennet sister, aged fifteen. 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. She later marries Mr.Wickham.
Charles Bingley has just rented 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 Mr. Darcy as being less intelligent but kinder and more charming (and hence more popular in Meryton). He lacks resolve and is easily influenced by others.
George Wickham is an old acquaintance of Mr. Darcy, and an officer in the militia unit stationed near Meryton. A superficially charming man, he forms a friendship with Elizabeth Bennet, prompting many to remark upon his suitability as a potential husband. He spreads numerous tales about the wrongs Mr. 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 more wronged man in their acquaintance.
Mr. William Collins is Mr. Bennet's cousin and a clergyman. Since Mr. Bennet has no sons, Collins is in line to inherit Mr. Bennet's estate. Jane Austen described him as "not a sensible man, and the deficiency of nature had been but little assisted by education or society". Collins is thought to be naively stupid by Mr. Bennet, and Elizabeth rejects his marriage proposal. She is very distressed when her friend Charlotte Lucas decides to marry Mr. Collins out of interest in his estate rather than his personality. Collins constantly boasts about his acquaintance with the wealthy and pompous Lady Catherine de Bourgh.
Lady Catherine De Bourgh is haughty, egotistical, and domineering. Because of her wealth and social standing she believes she can command anyone around her. People such as Mr. Collins contribute to this personality by acting as sycophants who bow to her every command. Her nephew Darcy initially does whatever his aunt requests out of respect for her, but by the end of the text, he makes the choice to go against her wishes and marry Elizabeth.
