Alice Warren was the daughter of Viola Thompson and Beauford Warren and the sister of Jack Warren. She married a man named Joseph Litchfield and had two children, Joseph Litchfield Jr. and Emma Litchfield.
In Happy Birthday Pip! You're A Witch!, the souls of deceased Warren witches entered Pip Muniz-Halliwell -- who was in his mother's body at the time -- in order for him to overpower the demon, Juno. It's possible that Alice was one of the many Warren souls who helped Pip.
