Which female character in Dracula becomes a vampire after being bitten?

Lucy Westenra becomes a vampire after being bitten and repeatedly attacked by Count Dracula. In Bram Stoker’s novel, Lucy is a 19-year-old wealthy young woman and Mina Murray’s best friend. She receives marriage proposals from Arthur Holmwood, John Seward, and Quincey Morris on the same day, ultimately accepting Arthur’s proposal.

Soon afterward, Lucy begins sleepwalking and suffers a mysterious illness marked by severe blood loss. Abraham Van Helsing recognizes that a vampire is feeding on her and tries to protect her with garlic and other precautions. Dracula repeatedly reaches her despite these efforts, and Lucy eventually dies. About a week after her burial, she rises as a vampire and begins attacking children, earning the nickname “Bloofer Lady.”

Van Helsing, Arthur, Seward, and Quincey later enter Lucy’s tomb and destroy her undead form by staking her, decapitating her, and placing garlic in her mouth. Mina Harker is also bitten by Dracula in the novel, but she does not become the vampire character described in this question. Lucy’s transformation is one of the story’s key turning points.
