There she plays the tough as nails matriarch of the Halliwell clan. Although not a regular, she has appeared in all eight seasons of the series. Her recurring role as “Grams” is her second regular series though, her first being Nightingales as the character Effie Gardner.
Name: Penelope Halliwell Johnson
Nickname: Penny
Birthday: 23 June 1937
Died: 5 March 1998
Astrological sign: Cancer
Husband/Wife: several marriages, first one Allen
Jack Johnson
Powers: Telekinesis
Penny harboured the power of Telekinesis, passed down to her through the Halliwell/Warren bloodline. This power enabled her to move objects with the mind. As with her descendant, Prue, Penny was able to channel her power through her hands, and displayed great skill with this gift. Her power still survives today, as Penny uses it to flip the Book of Shadows to guide her grand-children, the Charmed Ones. Penny Halliwell was the grandmother of the Charmed Ones. Penny took care of the girls after their mother was killed by a water demon, and the differences and worrying conflicts between them all forced her to consider binding their Charmed powers before they discovered they had them. Grams died after a heart condition overcame her. She died with her grandchildren beside her bed in the San Francisco Memorial Hospital. Her spirit lives on, however, helping and guiding the Charmed Ones. She appears every now and again in order to aid her grand-daughters, and even married Piper and Leo as a High Priestess.
