Paige was born on August 2nd, 1977 to Warren witch Patty Halliwell. Unlike the first three daughters Patty had with her mortal husband Victor Bennett, Paige was fathered by Patty's whitelighter, Sam Wilder. Patty initially wanted to keep the baby and raise her along with Prue, Piper and Phoebe, however, in those days, it was not only forbidden, but unthinkable for a witch and a whitelighter to be romantically involved. By this time, Patty and her mother, Penny, had known for at least two years that Patty's daughters were destined to become the Charmed Ones, witches destined to be bestowed with great power and the duty to protect the innocent. Penny feared that the Elders would deny the girls their birthright if they ever found out about Patty and Sam's affair. Patty and Sam decided to give the baby up for adoption.
The day Paige was born, Patty and Sam orbed to a local church and left her with a nun called Sister Agnes. They asked that she would find her a good home and Patty had only one request; that her name began with a "P".
Not long after, Patty was killed by the Water Demon. This gave her a chance to look over Paige for the first time. Patty noticed that her wishes were granted, Paige was being raised in a good home by the Matthews.
