P. Baxter

P. Baxter is the past life of Piper Halliwell. She was the cousin of P. Russell and P. Bowen, married to Gordon Johnson and was the mother of Penny Halliwell, the grandmother of Patty Halliwell and the great-grandmother of the Charmed Ones (Prue, Piper, Phoebe, and Paige).

Background
Her parents Redmond and Philippa Baxter built Halliwell Manor, a hosue Baxter grew up in. She hosted a speakeasy at her and Gordon's house due to prohibition. Both Baxter and Bowen murdered their cousin after learning Russell had fallen towards darkness because her boyfriend, Anton, was an immortal warlock. They cursed her and her future lives to die as well to ensure that Anton and Russell would never be reunited. It is said that Baxter's great-granddaughter, Paige inherited her eyes and good looks.
