The Marvil consists of Merri-Lee Marvil, the matriarch and single mother rasing her three daughters: Ryan, Jamie and Dylan. They live in a house (sometimes called a house, other times called an estate, but assumed to be a mansion) on top of a hill that looks like a church. It is discribed in The Clique as "a tall white A-frame that sat on top of a small hill. It looked more like a church then someone's home." Merri-Lee has a two-story walk in closet that is mentioned in The Boots Are Made For Stalking.
Merri-Lee's ex-husband and father of the girls left them prior to Charmed and Dangerous.
