Seamus Finnigan is an Irish half-blood wizard who attended Hogwarts School of Witchcraft and Wizardry in the same year as Harry Potter and was also in Gryffindor House. While he was not one of the first to believe that Lord Voldemort had returned, he joined Dumbledore’s Army and fought in the Battle of Hogwarts.

About Seamus Finnigan

Blood StatusHalf-blood
Zodiac SignSagittarius (speculative)

Seamus Finnigan was born to Irish parents. His mother was a witch and his father a muggle. According to Seamus:

I’m half-and-half. Me dad’s a Muggle. Mum didn’t tell him she was a witch ‘til after they were married. Bit of a nasty shock.

Harry Potter and the Philosopher’s Stone

So, Seamus grew up understanding both the wizarding and the muggle worlds. He was probably from Kenmare in County Kerry as he supported the local Quidditch team.

Seamus at Hogwarts – First Year

When Seamus arrived at Hogwarts in 1991, he was sorted into Gryffindor. This was probably the same house as his mother and his older cousin Fergus. But the sorting hat took almost a minute to place Seamus, suggesting that the decision was not straightforward. He soon formed a fast friendship with fellow Gryffindor Dean Thomas.

Seamus was also friends with Harry Potter. He supported Harry when he joined the Gryffindor Quidditch team, though warned him that seekers are often targeted for physical attacks. He also lent Harry his wizarding chess set when he went home for Christmas.

Seamus was eager but took a while to master his magic. He told everyone that he spent most of his youth flying around on a broomstick but did not seem more experienced than the others in their first flying lesson. When he first tried to master the levitation charm, he set his feather on fire.

Seamus at Hogwarts – Second Year

Seamus was one of the students initially impressed by Gilderoy Lockhart when he arrived as Defence Against the Dark Arts teacher. However, he didn’t believe that the Cornish pixies that Lockhart released during his first lesson were particularly dangerous.

Seamus displayed a curious nature. He was the student who asked Professor Binns in History of Magic whether anyone but the Heir of Slytherin would be able to open the Chamber of Secrets. He was also excited to join Lockhart’s duelling club. He was partnered with Ron, whose managed wand knocked Seamus to the ground accidentally.

Seamus at Hogwarts – Third Year

Just as Harry, Ron, and Hermione would often get together outside of school, Seamus and Dean’s friendship went beyond Hogwarts. In their third year, they went to Diagon Alley together to buy their school supplies. Seamus’ family was able to help Dean as he was muggle-born. This was not too different from Harry and the Weasleys.

Third-year students started divination in their third year and Seamus was not impressed by Professor Trelawney. When she claimed to be able to see a Grim in Harry’s cup, he commented that if he turned his head one way, he could see a Grim, but the other way it looked like a donkey.

Seamus followed the hunt for fugitive Sirius Black in the paper and on one occasion was the first to tell Harry and Ron that Black had been sighted near Hogsmeade.

But Seamus’ greatest fear was not Black. When he faced the Boggart in Professor Lupin’s Defence Against the Dark Arts class it became a banshee, with floor-length black hair and a skeletal green face. He used the Riddikulus charm to take her voice away.

Seamus at Hogwarts – Fourth Year

An adamant Quidditch fan, Seamus attended the Quidditch World Cup before the start of term, taking his friend Dean Thomas with him. Naturally, Seamus supported the Irish National Team. Ireland won, and Seamus was still wearing his Ireland rosette at the start of term.

Seamus was one of the students who assumed that Harry put his own name in the Goblet of Fire to become Triwizard Champion. But he thought this was great and supported him. Earlier he had commented that he was surprised that Cedric Diggory entered, as he would not want to risk his good looks.

Seamus attended the Yule Ball with fellow Gryffindor Lavender Brown. Like everyone, he was shocked by the death of Cedric Diggory and the stories of the return of Lord Voldemort.

Seamus at Hogwarts – Fifth Year

Seamus’ mother, a devout reader of the Daily Prophet did not believe Dumbledore that Lord Voldemort had returned and taught her son that this was not true. Seamus was not shy about telling Harry that his mother didn’t want him to return to school because of Harry.

Seamus thought that Harry was crazy and that Ron was just as crazy for believing him, and he did not want to share a dorm with the pair. But he did not make trouble and instead just kept away from them as term progressed.

However, after Harry’s interview with Rita Skeeter appeared in the Quibbler, Seamus and his mother had a change of heart. Seamus apologized to Harry for not believing him from the start.

This meant that Dean was able to bring Seamus along to the meetings of the DA in which Harry was teaching his fellow students defence against the dark arts. Early on Seamus was able to conjure a full Patronus, though he wasn’t sure exactly what it was. He described it as “something hairy”, and later learned that it was a fox.

Seamus at Hogwarts – Sixth Year

There were several openings in the Gryffindor Quidditch team in Seamus’ sixth year, and he tried out for the team with a lot of other people. However, he was outflown and the Chasers on the team were Katie Bell, Ginny Weasley, and Demelza Robins.

Later, when Katie was in St Mungo’s, Harry asked Dean to fly in her place. He knew that this would upset Seamus who desperately wanted to be on the team.

Seamus was shocked by the death of Dumbledore at the end of the year and insisted on staying for the funeral, despite the fact that his mother wanted him to return home immediately.

Seamus at Hogwarts – Seventh Year

Seamus returned to Hogwarts when it was under Death Eater control with Severus Snape as headmaster. He had no choice as all wizards were required to attend. He missed his friend Dean Thomas, who was forced to go into hiding as muggle-born.

Seamus was part of the reformed DA, under Neville Longbottom and Ginny Weasley, who worked hard to make life difficult for the Carrows, two Death Eater teachers, and Professor Snape.

By the time Harry, Ron, and Hermione showed up at Hogwarts, he was one of the students hiding out in the Room of Requirement. He was punished so severely under the new regime that he was hardly recognizable under all the bruises.

When Lord Voldemort attacked the castle, Seamus stayed to fight. Professor McGonagall noted that he had a talent for pyrotechnics and called on him to blow up the Wooden Bridge to impede entrance to the castle.

During the battle, he also cast a Patronus alongside Luna Lovegood and Ernie Macmillan to hold back hundreds of Dementors. He later gave support to Aberforth Dumbledore. He survived the battle and was seen talking and laughing with Dean and Aberforth in the Great Hall afterward.

Seamus Finnigan Personality Type & Traits

Seamus seems a fairly carefree and fun-loving person, except when someone challenges his friends or family. Then he can become ferocious and loyal. He stood up to his mother when it came to the death of Dumbledore and wasn’t afraid to face physical harm to challenge Death Eaters at Hogwarts.

He shows deep respect for his mother, family, and traditions and is proud of his Irish roots. His mixed background makes him very accepting of other people. He also is not afraid to admit when he is wrong, like he did with Harry after the Quibbler article.

Seamus Finnigan Zodiac Sign & Birthday

We do not know Seamus’s birthday, but he must have been born in 1979/80 to have been in the same year at school as Harry. Some fans speculate that he is a Sagittarius. They are fierce and loyal fire signs but are more relaxed and tranquil than the other fire signs.

Self-confidence and pride in their heritage are also Sagittarius traits, but they tend to be open minded and accepting of things that are new and different.
