The Wailing Widow was a female ghost from Kent. She was a close friend of Sir Nicholas de Mimsy-Porpington as she attended his five-hundredth Deathday Party, having had to travel all the way from Kent to Scotland.
- In the Danish translation of the Disc 2 of Harry Potter and the Chamber of Secrets, Travels with Trolls's title was mistranslated as Danser med Den Hvide Dame which means Dancing with the Wailing Widow. However due to a long line of mistranslations in the series, it could be; a) a mistake, b) a chapter in the original book.
