"He, as you saw, was left in squalor and poverty, with a very nasty temper, a fantastic amount of arrogance and pride, and a couple of family heirlooms that he treasured just as much as his son, and rather more than his daughter."
— Dumbledore's description of Marvolo's nature[src]

Marvolo Gaunt (fl. 1925) was a pure-blood[3] wizard of the House of Gaunt and descendant of Salazar Slytherin. He was the father of Merope Riddle (née Gaunt) and Morfin Gaunt, the maternal grandfather of Tom Marvolo Riddle (later known as Lord Voldemort) through his daughter Merope, and the great-grandfather of Delphini. Marvolo and his two children lived in poverty and squalor.

Violent and bigoted, Marvolo died soon after being released from Azkaban, where he was briefly imprisoned for assaulting Ministry personnel.[5] He was also the owner of a large golden ring and Salazar Slytherin's Locket, both of which he prized as heirlooms of his pure-blood heritage.


Early life[]

"Salazar Slytherin's! We're his last living descendants, what do you say to that, eh? Don't you go talking to us as if we're dirt on your shoes! Generations of pure-bloods, wizards all — more than you can say, I don't doubt!"
— Marvolo regarding his own ancestry[src]

Marvolo was born into the pure-blood House of Gaunt as he and his children, Morfin and Merope were among the last living descendants of Salazar Slytherin. Centuries of inbreeding caused poverty and a vein of instability and violence to flourish in the family. "This lack of sense coupled with a great liking for grandeur meant that the family gold was squandered several generations before Marvolo was born." As a result, he and his children lived in poverty in a ruined cottage near Little Hangleton. Despite his opinion of being of high birth, he was known in the village as a tramp.

Marvolo and his children, Morfin and Merope

Marvolo usually spent his time brandishing family heirlooms, including: A locket, a ring which he praised as much as anything, even his children. Marvolo had a loyal relationship with Morfin, since they both shared some similarities. This included belief in blood purity, being violent and being abusive towards Merope.

Unlike his relationship with Morfin, Marvolo hated his daughter, whom he called a Squib as a slur since she could not perform magic correctly. In all probability this was due to the abuse she received from her father and brother; Marvolo frequently abused her while Morfin watched and laughed.


Marvolo: "Should've made your presence known, shouldn't you? This is private property. Can't just walk in here and not expect my son to defend himself?"
Bob Ogden: "Defend himself against what, man?"
Marvolo: "Busybodies. Intruders. Muggles and filth."
— Marvolo showing his prejudiced and bigoted nature[src]

Morfin, being mentally deranged and having little regard for secrecy, frequently used magic in front of, and upon, Muggles, with his father approving of his actions. This inevitably brought him into conflict with the Ministry of Magic. When the Head of the Magical Law Enforcement Squad, Bob Ogden, visited the Gaunts to address the issue, they resisted violently. Marvolo justified Morfin's actions and resisted Ogden's calm attempts at discussion.

Just as Ogden rose to leave, Morfin ruthlessly revealed that Merope had a romantic admiration for the Muggle he had attacked: Tom Riddle Snr. Marvolo became absolutely infuriated (seeing as they were purebloods and only associated with their kind) and attacked his "filthy little blood traitor" daughter, though Ogden stopped him from strangling her by using a Revulsion Jinx.[5]

Morfin then defended his father from further attacks by firing a storm of jinxes towards Ogden. Ogden Apparated back to the Ministry and returned with reinforcements within fifteen minutes. Marvolo and Morfin both resisted, injuring several Ministry officials, but they were eventually subdued and placed under arrest. Both men were brought before the Wizengamot. Marvolo was brought to trial, being charged with attacking the Squad, resisting arrest, obstruction of justice, attempted assault on a witch, and contempt of Wizengamot.

Marvolo Gaunt was found guilty on all counts, and in mid-to-late 1925, was sentenced to six months imprisonment.[6] His son also stood trial with Marvolo for being an accomplice during Marvolo's fight with the Law Enforcement Squad, in addition to a trial for separate charges, and was sentenced to three years' imprisonment.[5]


Morfin Gaunt: "She likes looking at that Muggle. Always in the garden when he passes, peering through the hedge at him, isn’t she? And last night —"
Marvolo: "Is it true? My daughter — pure-blooded descendant of Salazar Slytherin — hankering after a filthy, dirt-veined Muggle?"
— Discussion of Merope’s infatuation with Tom Riddle Snr[src]

Merope, once Marvolo and Morfin were safely in prison, found herself alone and free for the first time in her life, and her magical abilities, which were suppressed by years of torment from her father and brother, flourished. She took the opportunity to escape from the desperate life she had led. Using either the Imperius Curse or a Love potion Merope seduced and married Tom Riddle Senior.[5]

While Bob Ogden's visit was the last time Marvolo saw his daughter. When Marvolo became a free man again and returned to Little Hangleton, his expectation of his return to his shack would be to see Merope dutifully waiting for him and serving a hot meal in anticipation of his homecoming. Instead he returned to an empty house with plenty of dust and a letter from Merope telling Marvolo she had gotten married and who his son-in-law was.

Marvolo never mentioned Merope's name or acknowledged her existence from that day forward; indeed, the shock of her desertion likely led to his early death. Furthermore, he had been greatly weakened by his time in prison, and he had possibly never learned to feed himself. The date of Marvolo's precise death is unknown, but he had already died by the time his son was released from Azkaban and returned to Little Hangleton.[5]


After Marvolo's death, the ring was worn by his son Morfin. It was then stolen by Marvolo's grandson, Tom Riddle, who turned it into a Horcrux after murdering his own father (and Marvolo's son-in-law) and then buried it under the floorboards of the house.

When his grandson, Tom, came to visit the Gaunt Shack in the hopes of meeting his magical lineage, he was disappointed, though not saddened, to hear from Morfin that Marvolo had long since passed away. The deteriorating conditions of the shack made Tom realise how poor Marvolo had been, which furthered his disappointment.

For the few people who still knew him, Harry Potter was among those who looked down on Marvolo for his elitist arrogance and deplorable household. Harry called him "an ignorant old git who lived like a pig". His abuse over Merope further influenced Harry's negative opinion.

By 2020, so much research had been made about Voldemort's past that at least one book had been published about Marvolo. Considering the title of this book, it is possible that the author wanted to reveal to the wizarding world the connection between the narcissistic "Lord" Voldemort and his indignant grandfather. In addition, Marvolo posthumously became a great-grandfather when Voldemort sired an illegitimate daughter Delphini.

Physical appearance[]

"An elderly man had come hurrying out of the cottage, banging the door behind him so that the dead snake swung pathetically. This man was shorter than the first, and oddly proportioned; his shoulders were very broad and his arms overlong, which, with bright brown eyes, short scrubby hair, and wrinkled face, gave him the look of a powerful, aged monkey."
— Description of Marvolo's outward appearance[src]

Marvolo is described as being shorter than his son, though oddly proportioned; his shoulders were very broad and his arms rather long for his body type. This, along with his bright brown eyes, short scrubby hair, and wrinkled face, made him look like a powerful, aged monkey like his ancestor, Salazar Slytherin.[5]

Personality and traits[]

"Marvolo Gaunt was an ignorant old git who lived like a pig, all he cared about was his ancestry. If that ring had been passed down through the centuries, he might not have known what it really was. There were no books in that house, and trust me, he wasn’t the type to read fairy tales to his kids. He’d have loved to think the scratches on the stone were a coat of arms, because as far as he was concerned, having pure blood made you practically royal."
Harry Potter's opinion of Marvolo[src]

A man who could most charitably be described as a violent, bigoted, mindless old fool, Marvolo placed the utmost importance on his heritage, leading him to be derisive of his daughter's seeming lack of magical ability and furious with her infatuation with a Muggle. He was cruel and bigoted, calling Bob Ogden a Mudblood, without actually knowing his blood status, and completely indifferent to the Ministry's authority.

His violence had led him to the point of being murderously unloving towards his daughter, though he respected his son enough to have a fair conversation with him. His hate for his daughter rendered him to treat her nothing short of a slave, and refused to acknowledge her existence ever again when she betrayed their clan, which may be one of the contributions that led to Marvolo's death. Another possibility is Marvolo simply never learning to feed himself, making him completely reliant on Merope to survive, despite his hatred towards her.

According to Dumbledore Marvolo cherished his family heirlooms as much as his son, and more than his daughter.[5] Another sense of irony in Marvolo Gaunt's character was his anti-intellectualism, despite his boastfulness about being a wizard. Marvolo did nothing in his power to improve his wizarding skills, as he did not own any wizarding books nor borrow them from friends or a library.

More than likely, Marvolo was ingrained with an imperious attitude and the belief that his own natural ability and blood status was all that he needed to be a successful wizard. When encountered by Bob Ogden and being told that he should have some awareness about his son's running afoul of the law due to an owl serving Morfin's warrant, Marvolo rebuked "I have no use for owls. I don't open letters", causing Ogden to rebut ignorantia juris non excusat (ignorance of the law excuses no one).[5]

Magical abilities and skills[]

"Get in the house. Don't argue."
— Marvolo speaking to Morfin in Parseltongue[src]
  • Parselmouth: Like his ancestor, son, daughter, and grandson, Marvolo had the ability to speak to snakes from their ancestor and even communicated with his children that way.[5]
  • Martial magic: Marvolo opened fire on Merope to punish her for lusting after a Muggle, but he was thwarted from this attack by Bob Ogden, who stunned him in order to defend her. It is also said that he injured some of the Ministry wizards that Bob Ogden brought back with him leading to his arrest, showing he had some skill in duelling.[5]



Morfin Gaunt[]

Marvolo's relationship with his children was terrible. He seemed to tolerate and maintain a tenuous relationship with his son Morfin, who was furiously loyal to Marvolo and his family's ideals, while just as unstable and violent. He seemed to be the only man Morfin feared and respected, as evidenced by his orders that Morfin go indoors and not backtalk him when Ogden paid a visit.

Despite Morfin's mostly positive relationship with his father, he nevertheless feared Marvolo's wrath. Morfin obeyed the order to enter the house without question, and fell into a state of insane fear that Marvolo would kill him for losing the family signet ring for the rest of his life, unaware that the ring had been stolen by his nephew.

Merope Gaunt[]

Marvolo seemed to have no care whatsoever for his daughter Merope, whom he derided as being a Squib and expected to do all the cooking and cleaning. He and Morfin were both emotionally and physically abusive towards Merope.

When Marvolo learned of his daughter's limerence for Tom Riddle, he flew into a rage and attempted to harm her, totally oblivious to the fact a Ministry Official was in his home and he was caught red-handed. Marvolo also conversed with his children in Parseltongue.[5] It was never mentioned about Marvolo's wife or how she was absent from the Gaunt shack (arguably most likely dying sometime before the arrest of her husband and son), but it could be surmised that given his terrible treatment of Merope, Marvolo also made for a horrible husband.

Marvolo never saw Merope again after he was imprisoned since she abandoned the shack for good, which led to her father to never speak of her existence again either. Despite genuinely hating Merope to the point of attempting to execute her for her crimes against the family's belief, Albus Dumbledore speculated that her abandonment was what contributed to Marvolo's early death, either due to the shock or that he never learned how to feed himself (as he had foolishly believed that Merope would be dutifully wait for his return from prison with a hot meal on the table). This shows that he is at least dependent on her for survival. Marvolo never saw Morfin again either after being released from Azkaban since Marvolo died before his son's sentence was complete; his family signet ring, the last heirloom, was left for Morfin to wear.

Despite being at the receiving end of Marvolo's abuse, Merope apparently cared enough for her father to use his name for her son's middle name. Alternatively, it could be that "Tom" and "Marvolo" were the only names that Merope could think of in her dying moments. This was likely due to Merope's Gaunt upbringing, during which she was shunned by both Muggles and wizards. This left Marvolo and Morfin as the only men that she regularly interacted with before her marriage to Riddle, Snr.

Tom Riddle Senior[]

It is unknown if Marvolo and Tom Riddle Senior had met in person, but it is known that Marvolo despised him very much. When Morfin revealed that Merope was in love with him, Marvolo became furious and angry since he was a pure-blood supremacist and didn't want any non-pure bloods into his family lineage. Marvolo presumably considered him more disgusting when he learned that she took advantage of his internment in Azkaban to elope with Tom.

Riddle Snr also seemed to be one of the indirect causes of Marvolo's death, because since Merope left the house, Marvolo had been shocked by this news to the extent that he never publicly mentioned that Merope existed from that day forth. It could have been possible that the shock was acute enough that it damaged Marvolo's body with problems such as hypertension. This in tandem with the mental damage he suffered while in Azkaban, as well as Dumbledore's speculation he likely failed to learn self-sufficiency, contributed to Marvolo's doom by dying before his reunion with his children.

Tom Riddle Half-Blood Prince Profile

Tom Riddle, his grandson

Marvolo had never met Tom Marvolo Riddle since he had either been dead when Tom was born, or passed away shortly after the birth of his only grandson. However, his forename became Tom's middle name, which after exhaustive research of the family names, Tom used to trace his descent from the House of Gaunt. In the summer of 1943, when Voldemort set off for Little Hangleton, he was hoping to meet Marvolo, however was greeted only by Morfin, the last male Gaunt, as Marvolo had been dead for many years by now. The deteriorating condition of the household had deeply disappointed the young Tom.

After murdering his father, the younger Tom stole his grandfather's ring and took to wearing it. He later turned it into a Horcrux.

Although Tom never got the chance to meet his maternal grandfather, elements of Marvolo's despicable traits survived into the latter part of the 20th Century through a reign of terror against Muggles, Muggle-borns, Squibs and blood traitors. Marvolo Gaunt's hatred of non-wizards manifested itself when Tom (as Lord Voldemort) commanded the Death Eaters. It could be that Voldemort's own adult personality was not only due to his conception due to his mother's use of either the Imperius Curse or the Love Potion, but also the "vein of instability" caused by centuries of inbreeding in the Gaunt lineage. In short, Voldemort proved himself to be Marvolo's grandson and heir.

Despite this, it can be assumed that, had they met in person, Marvolo would have despised or at least looked down on his grandson due to his half-blood status.


  • The name Marvolo may have its roots from the Latin "malivolo", which translates accurately to "malevolent". It may also be derived from Malvolio, the name of a character from William Shakespeare's Twelfth Night. Malvolio is a Puritan who despises all kinds of fun and games, perhaps alluding to Marvolo's extreme prejudice and cruelty. An antithetical character, Benvolio, appears in Romeo & Juliet, who is a man of good cheer and tries to see the best in Romeo and his friends, translating accurately to "benevolent".
  • The word gaunt is defined as "haggard, drawn and emaciated" and "bleak, desolate".[7]

Behind the scenes[]

  • The name "Marvolo" changes in some translations so that the "TOM MARVOLO RIDDLE" anagram can translate.
  • The flashback of Marvolo Gaunt that Dumbledore shows Harry does not appear in the film adaptation of Harry Potter and the Half-Blood Prince, likely for timing restrictions. However, it was included in the original draft of the script.
  • In the sixth film, Marvolo's ring is said by Albus Dumbledore to have belonged to his daughter, but in a deleted scene of the next movie, the ring is said by Harry to have belonged to Marvolo and the locket to Merope.
  • Hogwarts Legacy features Fifth year Ominis Gaunt, who was Cruciated by his elder siblings in the early 1880s until he agreed to cast the spell on Muggles "for sport". Chronologically, Marvolo, who died an old man in late 1920s, could be one of these older Gaunts who tortured their little blind brother.


Notes and references[]

  1. Harry Potter and the Half-Blood Prince, Chapter 10 (The House of Gaunt) - His daughter Merope is about eighteen and his son Morfin is at least seventeen in the summer of 1925 when Marvolo and Morfin are arrested; Marvolo must have been at least seventeen when his daughter was born. He must have been much older than thirty-five that summer, however, since Harry described him as "elderly" with a wrinkled face.
  2. Harry Potter and the Half-Blood Prince, Chapter 10 (The House of Gaunt) - Sentenced after Ogden's visit in the summer of 1925 to six months in Azkaban, Marvolo Gaunt returns to an empty house. In order for Merope Riddle to have been married for a year by the time of the birth of her son, she must have eloped mid-to-late 1925, so Marvolo Riddle returned sometime afterwards between late 1925 and mid 1926. Morfin Gaunt, sentenced to three years in Azkaban at the same time as his father, returns home mid-to-late 1928 find Marvolo already dead
