She is the only granddaughter of Prue and Andy in an alternate reality where Wyatt, Ben, and Hope get stuck. She has been raised by her grandmother since her parents and grandfather are dead. Her mother was named Phoebe after the baby sister her grandmother lost when they were girls. When her mom died in childbirth, Phoebe past on the name to her daughter. As she grew up she chose to be called Phee, partially to distinguish herself from her mother and great-aunt, but also because she liked the name.
