The Crouch family is a fictional family that figures prominently in the plot of Harry Potter and the Goblet of Fire.

Barty Crouch was the head of the family. Though his wife has never been named, his son was named after him. Winky the house-elf served the family until she was sacked. When Barty Crouch Jr. was kissed by a Dementor, the Crouch bloodline ended forever.

Winky

Winky was the Crouchs' House-Elf, who unlike Dobby, didn't want to be freed. She guarded the family's many secrets, but when Barty Crouch Jr. was rescued from Azkaban by his father, he was kept under control with the Imperius Curse and forced to hide under an invisibility cloak at all times. Winky nursed Barty Crouch Jr. back to health.

She urged Barty Crouch to let his son attend the Quidditch World Cup. He agreed in the end, but neither knew that Crouch Jr was fighting the curse. While attending the World Cup festivities, Crouch Jr stole Harry Potter's wand and used it to conjure the Dark Mark. Winky was sacked because she was found with the guilty wand in her hand (but Crouch knew she had failed to keep Crouch Jr under control), the sacking absolutely disgusted Hermione Granger.

Winky now works at Hogwarts. She is very depressed and drinks a lot. Her family has served the Crouch family for generations. She still refuses to give away her old master's secrets. When a dementor kissed Barty Crouch Jr., the Crouch bloodline ended.

Winky is the best friend of Dobby who first appeared in Harry Potter and the Chamber of Secrets. This book, second in the Harry Potter series, became a film in which Dobby was a digital character. This method is expected to be reused when Dobby and Winky appear in the up and coming fourth movie.
