Hogwart's School for Witchcraft and Wizardry
Seamus Finnigan was a half-blood wizard, son of Mr. Finnigan, who was a muggle, and Mrs. Finnigan, who was a witch, something that shocked Mr. Finnigan when he first learned it. Seamus was a Gryffindor student at Hogwarts School of Witchcraft and Wizardry. He was also the best friend of Dean Thomas. Seamus originally doubted Harry Potter’s claim that Lord Voldemort had returned in 1995, as his mother doubted it, too. However, he eventually joined Dumbledore’s Army in his fifth year, after apologizing to Harry. In 1997, he continued his seventh year at Hogwarts, although the school was under the control of Voldemort. Seamus remained in the D.A. in his seventh year and fought in the Battle of Hogwarts.
Born around 1980, Seamus was the son of a Muggle father and a magical mother.1 He had an older cousin, Fergus, who would frequently Apparate just to annoy him. Seamus had plans to annoy Fergus back, once he passed his Apparition test. Seamus was of Irish descent.
Seamus arrived at Hogwarts School of Witchcraft and Wizardry on 1 September, 1991. Other students in his year included Harry Potter, Ron Weasley, Hermione Granger, and Draco Malfoy. When Professor McGonagall asked the first years to form a line, to head into the Great Hall, Seamus ended up in front of Harry Potter. When Seamus’ name was called during the Sorting ceremony, he waited for almost a minute before the Sorting Hat placed him into Gryffindor.
After joining the Gryffindor table, Seamus was introduced to the Gryffindor house ghost Nicholas de Mimsy-Porpington, who students often called “Nearly Headless Nick.” Seamus asked how one could be “nearly” headless, to which Nick demonstrated by pulling his head off of his neck, which disgusted most of the table.
