Looking for Sherlock Holmes names?
It’s not quite like Harry Potter or Game of Thrones. Even Downton Abbey feels like more likely inspiration.
But the world of Sherlock Holmes is vast, and the character names range from the classic to the distinctive.
Besides, while Sir Arthur Conan Doyle penned 62 cases – 4 novels, 58 short stories – the adventures don’t stop there.
We re-invented and re-tell the tales across the ages. At one point, Robert Downey Jr., Jonny Lee Miller, and Benedict Cumberbatch all played the legendary detective during the same decade.
Some of those stories have expanded on the original Holmes family, including the recent books-turned-Netflix movies centered on little sister Enola. Imitating Sir Arthur Conan Doyle necessarily means finding interesting names for characters in the Sherlock Holmes universe.
The latest installment in the extended Sherlock Holmes universe: Hero Fiennes Tiffin is starring in Young Sherlock on Amazon Prime.
So if you’re a fan of the stories, maybe you’d like to name your child accordingly? These Sherlock Holmes names are nicely British, and connected to the series in a way that a fan might recognize. (Or not. Many are quite subtle!)

ABOUT THE NAME SHERLOCK
Before he was officially known to the world as the Great Detective, Sherlock Holmes, Sir Arthur Conan Doyle toyed with the name Sherrinford Hope. Or possibly Sherringford.
The name Sherrinford surfaces in various in-world spin-offs, like the BBC’s Sherlock, but not necessarily as a character name. Instead, it’s a maximum-security prison. Other worlds have borrowed Sherrinford for a Holmes’ brother name.
SHERLOCK HOLMES NAMES
ADELA
A character from Spanish television series El problema final. Set during the 1950s, it imagines an actor famous for playing the part of Sherlock ends up investigating a crime in real life.
ADLER
The surname of Irene Adler, an opera singer turned adventuress who crossed paths with Sherlock. She appears frequently in several stories, including “His Last Bow.”
AGATHA
A housemaid in one of the Holmes stories, and a typical name from the era. While Agatha has yet to be revived in the 21st century, Aggie fits with Abby and Maggie.
ALICE
A go-to name for female characters, including Alice Turner in “The Boscombe Valley Mystery,” one of many instances of Holmesian deduction saving an innocent man, despite a large body of evidence suggesting his guilt.
AMELIA
Actress Blu Hunt played Amelia Rojas, a possible long-lost daughter for the detective, in a 2025 series from The CW.
ARTHUR
As in the author himself.
BAKER
For 221B Baker Street, one of the most famous literary addresses in the world. The Baker Street Irregulars are a group of young boys Holmes regularly pays to help with his investigations, as they slip by unnoticed on the streets of London. In 2021, a Netflix series titled The Irregulars focused on this group, some years later. They show named them Bea, Spike, Leopold, Jessie, and Billy. Other characters in the series, like Henry Baker in “The Adventure of the Blue Carbuncle,” shared the surname, too.
BARTHOLOMEW
The delightfully named twin brothers Bartholomew and Thaddeus Sholto appear in The Sign of the Four.
BASIL
English actor Basil Rathbone is one of the most famous men to ever don the deerstalker hat. In an homage to Rathbone, Spanish television series El problema final introduces us to Benjamin Basil, an actor famous for playing Holmes. When he encounters a murder while on vacation, Basil has to become the sleuth in real life.
BEATRICE
In Young Sherlock, Beatrice is the Holmes’ family youngest daughter.
BENEDICT
While he has plenty of competition, Benedict Cumberbatch is the modern answer to Rathbone.
BERYL
A character from “The Hound of the Baskervilles,” and a long neglected gemstone name for a daughter.
BUCEPHALUS
The most famous Bucephalus was Alexander the Great’s horse. The Greek name means stubborn – literally “bull-headed.” In Young Sherlock, a mustachioed Colin Firth plays an Oxford don named Bucephalus Hodge. Author Franz Kafka once used the name Bucephalus for a (human) character, too.
CHARLES
“The Adventure of Charles Augustus Milverton” was one of many short stories. The character is a villain – a blackmailer, eventually murdered. It’s such a typical name from the era, though, and Charles Augustus is too good of a combination to go unmentioned.
CONAN
Also borrowed from the author. While it might make some think Barbarian, Conan feels like an overlooked Irish classic these days.
CORDELIA
In Young Sherlock, the character’s mother answers to Cordelia. Arthur Conan Doyle was mostly silent on any details about the detective’s parents, so there was plenty of opportunity to shape their backstory to fit the plot.
DOYLE
As in Sir Arthur Conan Doyle’s surname.
DUNCAN
One of many criminals to cross paths with the detective, Duncan Ross goes by other names, including William and Archie.
EARNEST
In the Enola Holmes books, we meet a young Earnest Augustus, Lord Tewkesbury. He’s an even bigger part of the Netflix films. Louis Partridge plays Tewkesbury in the Netflix movies, and becomes a love interest for Enola. That might be enough to boost Earnest, except the character typically answers to Tewkesbury.
ELSIE
The American woman at the heart of the mystery in “The Adventure of the Dancing Men.”
ENOLA
What if Sherlock’s family included a little sister, every bit as good at cracking cases as her brother? Introduced in a series of YA novels by author Nancy Springer, Enola Holmes appeals to a new generation of fans. While Enola is often considered the word “alone” written backwards, the character explains that her mother gave it to her to encourage independence. With three successful Netflix movies based on the books, parents have noticed this name.
EUDORIA
The given name of the family matriarch, at least in the Enola Holmes stories. It means “good gift.”
EURUS
Enola is not the only sister ever invented for the super sleuth. The character Eurus is the secret Holmes sister in Sherlock. She tells us that her name is Greek for “the east wind.” Eurus is the most brilliant of them all, but she’s also downright mad and more than a little given to evil.
GARETH
Sir Arthur Conan Doyle gave us Inspector Lestrade with the first initial G. Various names fill in the blank over the years. The BBC’s Sherlock called him Greg; in Elementary, he’s the more British Gareth.
HELEN
Holmes and Watson come to the assistance of Miss Helen Stoner in “The Adventure of the Speckled Band.” A classic locked-room mystery, rumor holds that Doyle thought this among his very best Sherlock Holmes adventures.
HERO
When Benedict Cumberbatch moved into 221B Baker Street, some quipped that he was the first actor to play Sherlock Holmes with a name to rival the fictional character. Cumberbatch now has competition, thanks to Hero Fiennes Tiffin of Young Sherlock.
HILDA
A minor character from “The Adventure of the Empty House,” Hilda is a delightfully old school name that sounds just right in the Sherlock stories, but remains rare today. Her surname, Adair, also has possibilities – perhaps more than Hilda.
HORACE
Horace Vernet really was an eighteenth century French artist, noted for his depictions of battlefields, as well as portraits. In “The Adventure of the Greek Interpreter,” Sherlock claims descent from “Vernet, the French artist.” It’s worth noting that Horace was the youngest in a line of several artists with the same surname. But there’s something about Horace that feels like a fit for the Victorian world inhabited by the detective.
HUDSON
From Mrs Hudson, Sherlock’s long-suffering landlady.
HUGO
Sir Hugo Baskerville is the first victim in “The Hound of the Baskervilles,” the original family member to suffer the ill-effects of a curse.
IRENE
We first meet Irene Adler in the short story “A Scandal in Bohemia.” She appears in plenty of adaptations. Rachel MacAdams famously played the part opposite Robert Downey Jr. and Jude Law in the 2009 and 2011 movies.
JAMES, JAMIE
Many men answer to James, but one stands out in the world of Sherlock Holmes: Professor James Moriarty. He’s the detective’s nemesis, a ruthless, criminal mastermind. In 1893’s “The Final Problem,” we meet Professor Moriarty, and are led to believe that he kills Holmes in a struggle. Public pressure, of course, would bring Holmes back. 2000s television series Elementary made their Moriarty female, and called her Jamie.
JOAN
In 2012, the world met Jonny Lee Miller’s version of Sherlock, as a modern detective who left London for New York City, where he met Dr. Joan Watson. Lucy Liu plays the role. We first meet Joan as Sherlock’s sober companion, a specialist working to help the famous sleuth kick his heroin habit. Just like in the original stories, Watson quickly becomes the partner Sherlock didn’t know he needed.
JOHN
The given name of Dr. John Watson, veteran and medical man, who stumbles into his role as Sherlock’s chronicler and companion while looking for a room to rent. Actors to re-invent the role of Dr. Watson range from Jude Law to Martin Freeman to Lucy Liu – see Joan.
JOSIAH
A minor character – and victim – in “The Valley of Fear.”
MARY
Mary Morstan first appears in The Sign of the Four. Other adaptations borrowed Mary. In the BBC’s Sherlock, she’s John’s wife and a secret assassin.
MYCROFT
Sherlock’s big brother Mycroft Holmes is every bit as smart as his sibling, but also usually presented as more respectable. His name might be even less wearable than even Sherlock. As a surname, Mycroft probably comes from Meadowcroft – meadow plus field. Unlike other Holmes family members, Mycroft never changes.
ORMOND
Before the author settled on John Watson, Sherlock’s sidekick was set to be named Ormond Sacker.
SCARLET
Scarlett is wildly popular as a girl’s given name. But spell it with one T, and it evokes 1887 novel A Study in Scarlet, the first appearance of Holmes and Watson. The name comes from a famous line by Sherlock: “There’s the scarlet thread of murder running through the colourless skein of life, and our duty is to unravel it, and isolate it, and expose every inch of it.”
SHAW
In the 2025 series Sherlock & Daughter, the leader of the Baker Street Irregulars is Shaw McPherson.
SHERLOCK
The name Sherlock Holmes belongs exclusively to the fictional detective. It’s hard to imagine the name on anyone else. The world’s greatest detective was first named Sherrinford Hope and then Sherrinford Holmes, before becoming Sherlock. Chances are it started out as a surname, one the author might’ve seen in several places. In the year 2017, as the BBC series Sherlock was enjoying peak popularity, a dozen boys received the name in the US. As of 2025, it failed to rank in the US data.
SHOU’AN
Princess Gulun Shou’an is a major character in the opening story line of Young Sherlock. She’s called Shou’an; interestingly, it’s associated with a real 19th century princess from the Qing Dynasty. But Shou’an was more of a term of affection, rather than a personal name.
SIDNEY
One reason for the Sherlock Holmes stories’ success? The illustrations by Sidney Paget, an in-demand illustrator of the day. Paget gave the detective his iconic deerstalker hat and Inverness cape.
SILAS
Joseph Fiennes, uncle to Hero in real life, plays Silas Holmes. As with Cordelia, this character was invented for Young Sherlock.
THOMAS
In Elementary, Sherlock works closely with Captain Thomas “Tommy” Gregson of the NYPD. The show based Gregson on a character from the original stories.
TOBIAS
Inspector Tobias Gregson of Scotland Yard appears in several stories. Holmes considers him bright, by Scotland Yard standards – though that’s not exactly a compliment.
WATSON
Sherlock’s faithful sidekick, and chronicler of his adventures. His first name is John; middle initial H. It’s said that the author took his inspiration from a friend named James Watson.
WILLIAM
It’s too classic a name to feel closely linked to the stories, but it’s worth noting that William Gillette helped bring the Sherlock Holmes character to life on stage, and in a 1916 silent film. Gillette wore the deerstalker suggested in early illustrations, and added the famous curved meerschaum pipe.
This list barely scratches the surface of Sherlock Holmes characters, either from the original British author’s collection of stories and novels, or from the many adaptations across the years.
