Frances (Audra Lindley): Phoebe's grandmother by her mother Lily. Her only appearance is in "The One with Phoebe's Dad", where she reveals to Phoebe that the person in the pictures she keeps around the house is not Phoebe's father, which motivates Phoebe to try to track down her real father. When Phoebe leaves Frances’ house to go and find her father, she kisses goodbye to a picture of her "grandfather", which is in fact a picture of Albert Einstein. Though the character appears in only one episode, she is mentioned in a few more, including in season 5's "The One with Joey's Bag", where it is revealed that she has recently died and Phoebe plans her funeral. Phoebe inherits her grandmother's yellow taxi and apartment. She keeps the taxi until the very end of the series.
