When it comes to Harry Potter characters, muggles usually get the short end of the stick. Normally, these non-magic characters are regulated to nothing more than villains, comedy relief, or set dressing. But, every now and again muggles will feel a bit more relevant to the larger story being told.
These few principal characters sadly never enter the doors of Hogwarts. But, if they had been born into the wizarding world, how would they have fared at the famous wizarding school? Looking at the most prominent muggle characters of the series, here is their most likely Hogwarts House placement.
Vernon Dursley - Slytherin
This should come to a surprise to no one. Vernon's appearances throughout the books and films had been met with nothing but villainous characterization. For someone who hates the wizarding world so much, he would fit right in with the worst of them.
He embodies the worst aspects of Slytherin house, putting his ambition above all else in his life, and in doing so, forgetting his basic humanity. The treatment of his nephew directly affects the upbringing of his only child as well.
Petunia Dursley - Slytherin/Hufflepuff
Petunia is fairly similar in her behavior, but it is, more often than not, a mask that covers her true identity. If it wasn't for her innate jealousy which formed during childhood, Petunia would have been a very loving individual.
In fact, she still is, but only to those that she puts importance on, such as her son. Sadly, because of her upbringing and growing resentment, Petunia's worst sides came out, and she was molded by her insidious husband.
Dudley Dursley - Hufflepuff
Dudley surprisingly started out as one of the most disliked characters in the entire story, only to be happily redeemed near the end. In the book, as well as in a deleted scene, Dudley makes amends with Harry for their shared childhood, citing when Harry saved him from the dementors as a turning point.
It is this sharp turn in character that shows the path Dudley will eventually reach. On the inside, Dudley is nothing more than a soft-hearted kid who's parents stunted his social skills. As he grows, hopefully, he can make amends and become the most kindhearted self he can be.
Aunt Marge - Slytherin
If you thought Vernon was bad, he's got nothing on the nastiness of his sister. Marge is one of the worst individuals in all of the books. Not only does she share a similar moral compass as Vernon, putting ambition and gluttony before others, but her sickening bloodline obsession is alarming.
Like a scaled-down version of the bloodline beliefs of dark wizards, Marge's background as a dog breeder has affected her world view of purity. Marge looks at those who don't fit into her world view and believes that there must be something genetically wrong with them. Marge is literal trash.
Frank Bryce - Gryffindor
Frank is such a commendable character he gets far worse than he ever deserved. This war veteran turned the village pariah was accused of the murder of Tom Riddle Sr and his family. As the gardener and groundskeeper, Frank was the only one with keys to the home. But, he was acquitted and freed.
Sadly, he spent the rest of his days harassed by villagers. Still, after years of hatred towards him, he carried on his duties, facing off against Voldemort and his followers when they took over the Riddle House. If that's not commendable Gryffindor behavior, we don't know what is.
Tom Riddle Sr - Slytherin
Tom Riddle Sr certainly was the victim of Voldemort and the Gaunts. Getting drugged into loving someone and forced to bear their child is certainly unethical, to say the least. But, even though he was taken advantage of by Voldemort's mother, and later killed by Voldemort himself, Riddle was still a classist pig.
This rich aristocrat vilified the Gaunts for being poor and shoddy, making him out to be a real piece of work. His ambition and pride do not come across as the nicest of guys to know. But hey, at least we know where Voldemort gets it.
The Prime Minister - Ravenclaw
In the original novel Harry Potter and the Half-Blood Prince, the opening features a small vinette of Cornelius Fudge, Minister of Magic, visiting the British Prime Minister in 10 Downing Street. Though cut from the film, the scene shows how connected the muggle world is to the wizarding world.
The Prime Minister himself comes across as a bit of a stuffy intellectual type who gets flustered and stressed ad Fudge's lack of information. Though we don't spend a lot of time with him, this makes the Prime Minister out to be a Ravenclaw type, who approaches problems as logically and detailed as possible.
Mr. & Mrs. Mason - Slytherin
Mr. and Mrs. Mason attend the Dursley's dinner party in The Chamber of Secrets. To be honest, we don't get to see a lot from them in terms of personality. But, there are still a few clues that indicate what kind of people they are.
Firstly, if they will associate themselves with the Durselys, that's not a good look. Mr. Mason's affinity for golf, being a businessman, and laughing at Vernon's "Japanese Golfer Joke" also doesn't bode well for them. They seem to fit right into stuffy socialites, making them out to be similar Slytherins to the Durselys.
Mr. & Mrs. Granger - Hufflepuff
Similarly, the Grangers are rarely seen throughout the series. Briefly, they can be noticed speaking with Arthur Dursely and finally when their memories are wiped in The Deathly Hallows. But, considering who their daughter is, we can make a guess that these two individuals are loving and supportive parents.
Having a daughter turn out to be a witch could have destroyed their family. But, they took it in stride, and supported and loved Hermione the best they can. Also, considering Hermione's tragic reaction to having to wipe their memories means that they must have been loyal loving guardians. For that, we'll stick them with the Hufflepuff label.
Jacob Kowalski - Hufflepuff
For all the problems and issues that fans have incurred in regards to the Fantastic Beasts series, there is one aspect that nearly everyone can get behind: Jacob Kowalski. Seriously, this is the one addition from J. K. Rowling fans adore. The first lead muggle character in a Harry Potter property, Jacob is one of the most lovable and fun characters to follow.
His down to earth personality and loyalty to his friends marks him as a tried and true Hufflepuff. Not to mention, he gets along so well with Hufflepuff alum Newt Scamander. Finally, his connection to baked goods would feel right at home in the Hufflepuff Common Room (located right next to the kitchens.
