What is Howard and Bernadette's daughter's name?

Howard and Bernadette’s daughter is named Halley Wolowitz.

Halley is born during The Big Bang Theory’s later storyline about Howard and Bernadette becoming parents. Her name is a playful reference to Halley’s Comet, fitting the show’s habit of connecting character details to science and astronomy.

Halley is mostly kept offscreen during the series. Viewers commonly hear her crying, but the production uses that absence as a recurring joke, especially because Howard’s mother, Debbie, was also famously heard without being seen for much of the show.

The other options belong to different characters or relationships. Lucy Wolowitz is not Howard and Bernadette’s daughter, Priya is Raj’s sister, and Emily Sweeney is Raj’s former girlfriend. Howard and Bernadette later have a son named Neil Michael Wolowitz, making Halley the couple’s first child.
