Faith was the twin sister of Harmony's Grace Standish. It is unknown how Faith spent her life up until the age of forty. She and Grace were very close until the Boston fire that Faith believed killed Grace all those years ago. Unlike her sister, who knew nothing of evil thanks to her amnesia, Faith was obsessed with the idea that evil killed Grace, and was after her and her daughter. Because of that, she moved Charity and herself around constantly, the only memory of her sister a photograph the two had taken when they were twenty.

Because part of Faith had always believed that her sister was alive, which is why she would occasionally haunt the on-line chatrooms, looking to learn something about her sister. It was in an on-line chatroom that Faith was able to make a connection with Sam Bennett, who was looking for information about his amnesiac wife. Unfortunately, they were never able to connect. Even once Faith's niece Kay realized that her 'friend' Charity was really her cousin, Faith and Grace still couldn't meet, because Kay made sure that Grace never knew about her connection to Faith or Charity, in an effort to keep Miguel to herself.

Grace and Faith were finally able to connect, and were able to have one on-line conversation with each other, face to face for the first time in over twenty years. They barely had time to say hello when Tabitha, who had finally found Faith, managed to set the house on fire. Although Grace and Sam rushed out to Castleton and the fire department worked hard to save the house, they were unable to save Faith. She burned to death in the fire, and Grace never got to see her sister face to face. Faith's ghost has appeared to the family in times of trouble, though, usually to give advice to her clueless twin.
