It is known through SimPE that Roberta Smith is the mother of Robby Smith (hidden). She is not mentioned in-game at all, and only in SimPE. She isn't dead, but she can't be put back in the game. The reason she is there is unknown. Oddly, her memory of having Robby depicts that Mystery Sim is the father.
