Background information
Gormalith Gaunt murdered her sister and brother-in-law and kidnapped her niece Isolt Sayre and raised her in Coomcallee. She forced Isolt to watch as she jinxed any Muggle or animal that strayed too near their cottage. The community learned to avoid the place where Gormlaith lived, and from then on the only contact Isolt had with the villagers she had once been friends with, was when local boys threw stones at her as she played in the garden. She refused to send her to Hogwarts due to their enrollment of Muggle-borns. Isolt then developed the skill and courage to escape by stealing her aunt's wand and fled the country to the New World.
