On the American TV series 'Bones', what is Dr. Temperance Brennan's birth name?

Temperance 'Bones' Brennan, Ph.D. is a fictional character portrayed by Emily Deschanel in the American Fox television series 'Bones'. An anthropologist, forensic anthropologist, and kinesiologist, she is described in the series as a leading authority in the field of forensic anthropology. Brennan first appeared on television, along with other series characters, in the 'Pilot' episode of 'Bones' on September 13, 2005. She is the main protagonist of the series along with FBI Special Agent Seeley Booth (David Boreanaz).

Although Brennan seemed to have a relatively normal childhood, her parents disappeared when she was 15 years old. Her older brother Russ was unable to care for her and she was put in the foster care system.

In Season 1, Brennan asks Booth to look into her parents' disappearance. Season 2 uncovers her parents were bank robbers specializing in safety deposit boxes. They changed the family's identity after they stole some damaging FBI documents regarding the murder of an FBI agent and the false imprisonment of a civil rights activist. Brennan's birth name was Joy Keenan.

Brennan is loosely based on author Kathy Reichs' heroine in her crime novel series, also named Temperance Brennan. The main similarities the two share is their name and occupation as forensic anthropologists.
