Her father was involved in illicit activities, and he involved Reggie in it. They were eventually caught by Muggle police, and her mother tried to use her magic to help the two escape. She frightened the police and violated the International Statute of Secrecy in doing so. Her father and brother were taken to a Muggle prison, and her mother was sentenced to Azkaban for being found guilty of being a member of the Nocturnal Order of Tricks and Magical Exhibitions. The incident was put in a Muggle newspaper under the heading, "The Bloody Pages". Her younger brother, Daniel was put under her guardianship. He later began attending Hogwarts School of Witchcraft and Wizardry.
After Daniel went to school, Esme received a Christmas gift from him, a confidence boosting brew, but she sent it back since knowing him having brewed it was all the confidence-boosting she needed.
During the 2010–2011 school year, she visited Daniel in the Hospital Wing at Hogwarts after he had been hurt by some Acromantulas, and had a private conversation with Elliot Evers who had rescued Daniel. When Daniel later woke up from a bad dream about his parents, Esme discussed them with him and suggested he be friends with Elliot, from whom he could learn a thing or two.
She was later kidnapped by Victor Gridley and his associates. When her brother paid Gridley another visit in his caravan upon his request, Mr Pronk showed him Esme while Gridley reminded him of his debt. Daniel had no choice but to sneak Gridley into Hogwarts to get to Professor Longbottom in order to save Esme. She was eventually rescued from the dungeon of Gridley's caravan by her brother and his friends.
Esme was similar in appearance to her brother Daniel. She had light skin, brown hair and brown eyes.
