Grace Cahill (from Attleboro, Massachusetts) was the matriarch of the Cahill family. She died when she was seventy-nine years old. She had a jade necklace that she always wore until her death. She was a professional pilot, and had a private airplane that she flew around the world with, which she named "The Flying Lemur". During her life, she had been lonely due to the deaths of her relatives (her ex-husband Nathaniel Hartford, her daughter Hope Cahill, and her son-in-law Arthur Trent). Even though, she managed to keep all the Clues safe in her hands until her death just after she altered her will and thus started the quest. Her official cards are No. 59, No. 133, and No. 197.
