She is the younger daughter of Phoebe Halliwell and Cole Turner. She has one older sister, Colette. After her sister tried to kill her, Phoebe and Cole made the tough decision to hide their daughter away while they tried to figure out how to deal with their older daughter. It was supposed to be temporary, but days turned to weeks, weeks to months, months to years, and soon two years had passed and Cole was dead. After that Phoebe made the decision to let Meggie keep her child for good. Colette was too dangerous and Phoebe wanted her daughter to live. If Colette didn't know where to look, she couldn't hurt her sister.
