Pearl was mentioned as an aunt of Prue, Piper, and Phoebe Halliwell, and possibly Paige. She owned a couch, which was kept in the attic of the Halliwell Manor. During a fight with a Kazi Demon, a blind Piper accidentally combusted it. After she asked if she hit the Kazi, Phoebe told her that she "killed Aunt Pearl's couch".
- A theory among fans is that she may have been P. Russell, Phoebe Halliwell's past life.
