Mercy Tannen was the daughter of Goodman Tannen. She first encountered Marty McFly, going under the alias of "Martin", in 1692 during the Salem Witch Trials. She found his actions were unworldly and that he was speaking in strange tongues, and agreed with the rest of the townsfolk that Marty was a witch.
