Grace Cahill's branch of the Cahill Family is a member of the broader Cahill Family. Most of the blood family members belong to the Madrigal branch, though the family also has Lucian history (diluted over the generations), and some Ekaterina heritage mixed in to later generations. Though Grace was not the oldest member of the section of the family, she was one of the most influential members of the Madrigal branch, and the wider Cahill family. Other notable members of the family branch include Dan and Amy Cahill, Grace's grandchildren, who won the Clue Hunt.
