House Hetherspoon is a knightly house of The Westerlands situated south east of Lannisport. The daughter of Ser Tybolt Hetherspoon, Melara, was a friend of Cersei Lannister. She convinced Cersei into seeing Maggy the Frog and when Melara asked Maggy if she would marry Jaime, she was told about her imminent death. She later drowned in a well with Cersei hearing her cries.
