"Duncan was a mischief-maker. He put even Tulip an' Tonks ter shame."
Rubeus Hagrid regarding Duncan's mischief-making[src]

Duncan Ashe was a wizard who attended Hogwarts School of Witchcraft and Wizardry in the second half of the 20th century and was Sorted into Slytherin.


Hogwarts years[]

Duncan Ashe was friends with Jacob from his first day at school until his dying day. The two were noted to be mischief makers by others, and frequently visited Zonko's Joke Shop. At some point, he and Jacob also broke their brooms.[4] He was also friends with the school poltergeist, Peeves,[5] and with Olivia Green, a Ravenclaw student from his year.[6]

Sometime during the 1970s or 1980s, he died when compelled by R to concoct an Erumpent Potion, which exploded while he was preparing it and killed him.[4]


After his death, Duncan returned as a ghost and stayed at Hogwarts, though he rarely showed himself to the other residents of the Castle.[3]

During the 1988–1989 school year, he agreed to arrange a meeting with Peeves for Jacob's sibling so they could get the Vault portrait from him, where he warned them Peeves would request chaos on his terms.[7] He later helped Jacob's sibling appease Peeves by unleashing various forms of chaos upon the school in order to persuade Peeves to hand over the Vault portrait. He was also in the Prefect's Bathroom when Peeves offered them a self-portrait, which they politely declined.[5]

During the 1989–1990 school year, Jacob's sibling and Charlie Weasley sought him out in the Prefects' Bathroom, where Jacob's sibling expressed their apologies for not visiting him often and asked him for advice as to where he thought Jacob could be. He expressed the view that Jacob was purely selfish but that he would likely be found in the Boathouse, as that was where they both often hung out together while unwittingly working for 'R'. After that, he told Jacob's sibling not to hold their breath about their brother, as he never had any breath to hold anyway, and he vanished into the toilet cubicles.[8]

During the 1990–1991 school year, Duncan became reunited with Olivia and Jacob at Hogwarts. Although reluctant, Jacob's sibling persuaded him to meet them at the Great Lake, where he eventually embraced them as his old friends.[9]

Personality and traits[]

When he was alive, Duncan loved making mischief and was noted to be a mischief maker by others along with his friend, Jacob. After he died, he isolated himself and rarely showed himself to the other residents of the Castle. He was angry and resentful at Jacob for taking the blame for 'R' and joining them.

Notes and references[]

  1. He was in the same school year as Jacob, whose year of birth range is given as this. Jacob was expelled during the 19801981 school year. Angelica Cole knew Jacob when she was at school, and that was her first year, meaning he could not have been expelled before then, and Lord Voldemort, whom he was rumoured to serve, was vanquished on 31 October 1981, meaning he could not have been expelled afterwards. Since this was his final year, he must have been born in either of those two years.
