Phoebe Halliwell was born in her family manor at 1329 Prescott Street San Francisco, California on November 2, 1975 to the Charmed Ones mother Patricia Halliwell and mortal Victor Bennett.

Phoebe had two older sisters, Prue Halliwell and Piper Halliwell and a younger half-sister Paige Matthews.

Phoebe was named after the favorite aunt of her mother. Although Phoebe was born with the power of premonition, her maternal grandmother Penelope Halliwell bound the powers of her granddaughters to keep Nicholas from killing them and taking their powers. Her father and maternal grandmother argued about Victor being merely human and thus unable to protect his own children from the supernatural.

A disgruntled Victor eventually left his family.

On February 28, 1978, Patricia was drowned fighting the water demon.

Phoebe and her two older sisters were effectively orphaned and were raised by their maternal grandmother Penelope. Phoebe was a good student, and once earned an award for student of the month.

At the age of 10 Phoebe was transported by a spell cast by her future self to the year 2002, where she met two older versions of herself, her sister Piper, Piper`s husband Leo Wyatt, and Phoebe`s future ex-husband Cole Turner.

Cole protected her from the demon Kurzon and then she visited the realm of Whitelighters with Leo.

After she helped the older Phoebe listen to her heart about marrying Cole, she returned to her own time, where Penny quickly erased her memory of the time travel.

Unlike her sisters, Piper, Prue and later, Paige, Phoebe is more susceptible to turning evil because she is the only one of the sisters who was born in the Halliwell manor. After completing high school, Piper and Prue moved into an apartment together in North Beach where they stayed until their grandmother Penelope became ill and they moved back in with her.

Prue became engaged to a man named Roger and she asked Piper to be her maid of honor. Unfortunately, Roger began to hit on Phoebe at her bartending job and sent her flowers.

When Prue found out, she accused Phoebe of coming onto him.

Devastated at the accusation, Phoebe left for New York City.

She also did this because she had evidence that her father, Victor, was living there.

Around this time, Penny took a picture of the three.

Seeing how disconnected the sisters were, Penny planned to use a potion to bind the girls` powers forever, but she died before she could use it.
