Cornish names carry the weight of a language that nearly vanished. Kernewek, the Celtic language of Cornwall, was spoken continuously for centuries before dwindling to near-extinction by the 18th century, and the names that survive from it are some of the most distinctive in the British Isles. Whether you have Cornish roots or simply love names with genuine depth and rarity, this list draws from that tradition honestly.
These are real names that real people bear, not romantic inventions.
Classic Cornish Names for Girls
These are the names most firmly established in Cornish tradition, used for generations and still carried by Cornish women today.
Demelza
From the Cornish place name meaning “fort of Maelda,” Demelza is almost exclusively associated with Cornwall and has been used as a given name since at least the mid-20th century. It gained wider recognition through Winston Graham’s Poldark novels, but its roots as an actual Cornish place name predate that entirely. It sounds wild and earthy in the best possible way.
Morwenna
One of the great Cornish saints’ names, Morwenna is believed to derive from the Old Cornish word for “maiden” or possibly from a root related to “waves.” Saint Morwenna is venerated in several Cornish parishes, and the name has been used in Cornwall and Wales for well over a thousand years. It has a lyrical, flowing quality that feels both ancient and usable today.
Senara
Senara is the name of the patron saint of Zennor, a small village on the Cornish coast. The name’s exact etymology is debated, but it is genuinely Cornish in origin and has been revived as a given name by families with Cornish heritage. It is rare enough to feel genuinely special.
Rosen
Derived from the Cornish word “ros,” meaning “promontory” or “heath,” Rosen is an authentically Cornish feminine name. It appears in historical Cornish records and is distinct from the English “Rose,” though the two are sometimes confused. A quiet name with real roots.
Lowenna
Lowenna comes from the Cornish word “lowen,” meaning “joyful” or “happy.” It is a genuinely lovely name with a clear, positive meaning, and it has been used in Cornwall as a given name for centuries. The double-n ending gives it a softness that works beautifully in modern use.
Hedra
Hedra is the Cornish word for October and has been used as a given name in Cornwall, particularly for girls born in that month. It is one of the more unusual month-derived names in any language and has a strong, spare sound that sets it apart from anything else on a nursery list.
Jenna
While Jenna is now widespread, its origins in Cornwall are legitimate and predate its 20th-century popularity boom. It is considered a Cornish form of the name Jean or Jane, and it appears in Cornish records going back several centuries. If you love it for its Cornish roots specifically, that connection is real.
Classic Cornish Names for Boys
Cornish men’s names tend toward strong consonants and deep historical resonance, many tied to saints and medieval figures.
Cador
Cador appears in Arthurian legend as the Duke of Cornwall, making him one of the most specifically Cornish figures in the entire tradition. The name likely derives from a Brittonic root related to “battle.” It is rare in modern use, which makes it genuinely distinctive.
Conan
Several Cornish and Breton saints bore the name Conan, and it has deep roots in the Celtic world stretching from Cornwall to Ireland to Brittany. The Cornish saint Conan was a bishop, and the name was used regularly in medieval Cornwall. It is far more layered than its modern associations suggest.
Gerens
Gerens is the name of a Cornish saint and king, with a parish church at Gerrans in Cornwall dedicated to him. The name likely derives from a Brittonic root meaning “old.” It is genuinely rare outside Cornwall and carries the kind of historical specificity that name enthusiasts tend to love.
Mabyn
Saint Mabyn is another of the legendary children of the Welsh king Brychan, many of whom became patron saints of Cornish parishes. The name is preserved in the village of Saint Mabyn in North Cornwall. Historically used for both boys and girls, it sits in rare territory now.
Perran
Saint Piran, spelled Perran in some traditions, is the patron saint of Cornwall and of tin miners specifically. His oratory near Perranporth is considered one of the oldest Christian buildings in Britain. The name is deeply Cornish in its associations and has a strong, clear sound.
Ruan
Ruan is the Cornish form of Rumon, an early Celtic saint venerated in Cornwall. The parish of Ruan Minor and Ruan Major on the Lizard Peninsula preserve his name. It is a compact, handsome name that wears well in contemporary use while remaining genuinely rare.
Talan
Talan is a Cornish name found in historical records and revived in the modern Cornish language movement. It may derive from a root meaning “brow” or “forehead” in the sense of a hilltop. It has the clean, modern feel of names like Declan or Rowan while being far less common.
Carantoc
Saint Carantoc was a Welsh saint who is particularly associated with Cornwall and Crantock, the village named for him. The name is ancient and unmistakably Celtic. It is a bold choice, but for families with deep Cornish ties it carries real historical meaning.
Unisex and Gender-Flexible Cornish Names
The Cornish tradition includes several names used historically for both boys and girls, and that flexibility feels very much in step with current naming culture.
Pasco
Pasco is the Cornish form of Pascal, meaning “Easter” or “Passover,” and it appears in Cornish records as a name given to children born at Easter. It has been used for both boys and girls in Cornwall, though it leans masculine historically. It has a warm, unusual sound and a genuinely meaningful origin.
Nance
Derived from the Cornish word “nans,” meaning “valley,” Nance appears in Cornish place names and personal names alike. It has been used as both a masculine and feminine given name in Cornwall. Short, grounded, and rooted in the Cornish landscape.
Brane
Brane appears in Cornish name records and is linked to the Cornish word meaning “crow” or “raven.” It is rare and historically attested in Cornwall. The raven connection gives it a striking, slightly dark quality that suits parents drawn to nature-based names with edge.
Names from Cornish Legend and Arthurian Tradition
Cornwall sits at the heart of Arthurian tradition. Several names from that world are specifically Cornish in origin, not just generically Arthurian.
Iseult
Iseult (also spelled Isolde) is the Cornish princess at the center of the Tristan and Iseult legend, one of the great love stories of medieval literature. The name is believed to derive from a Germanic root meaning “ice rule” or “iron ruler,” though it passed into Cornish and Welsh tradition early. It is rare in modern use and unmistakably romantic.
Tristan
Tristan is a name of disputed etymology, possibly from a Brittonic root or shaped by the French word “triste,” meaning sad. What is clear is that the Tristan of legend is specifically a Cornish hero, the nephew of King Mark of Cornwall. The name has maintained quiet but steady use in Britain and the US and is one of the more accessible names on this list.
Melior
Melior is the name of the fairy woman in the Cornish-connected tale of Parthenopeus de Blois, and it appears in medieval Cornish literary tradition. The name is rare and genuinely historical, derived from the Latin root meaning “better.” It has an ethereal, medieval quality that wears surprisingly well.
Revived Cornish Language Names
The 20th-century revival of the Cornish language brought a wave of names drawn directly from Kernewek vocabulary and grammar. These names are used by real families in Cornwall today.
Elowen
Elowen comes from the Cornish word for “elm tree.” It has become one of the most successfully revived Cornish names and has a genuine following beyond Cornwall because of its beautiful sound. It is the Cornish name that most often surprises people by not being Welsh or Irish.
Tegen
Tegen derives from the Cornish word meaning “pretty thing” or “trinket,” and it has been used as a given name in Cornwall, particularly in the revival period. It is soft in sound and sweet in meaning without being saccharine. Pronounced roughly TEH-gen, it is simple to say once you know it.
Merryn
Merryn is associated with Saint Merryn, whose name is preserved in the parish of Saint Merryn in Cornwall. The name may derive from a Brittonic root, and it has been used as a given name for girls in Cornwall with particular consistency. It has the same appealing rhythm as Meryn or Merren without being a simple variant spelling.
How to Choose a Cornish Name
The first question worth asking is whether you want a name that is recognizably Cornish to most people or one that carries its heritage quietly. Names like Tristan and Jenna will pass as familiar anywhere, while names like Gerens or Senara will prompt questions. Both are valid goals, and the answer depends on how much you want the name’s origin to be part of the daily story.
Pronunciation is worth thinking through honestly. Many Cornish names are phonetically straightforward once you see the pattern, but names like Iseult and Carantoc will require a brief explanation everywhere outside Cornwall. If you want a name that is unusual but immediately speakable, Elowen, Lowenna, and Ruan are the easiest entry points.
Consider the saint’s parish connection if it matters to your family. Cornwall’s naming tradition is closely tied to its network of Celtic saints, and many of these names are literally embedded in the landscape. For families with roots in specific parts of Cornwall, choosing the name of that parish’s patron saint is a meaningful act of heritage, not just aesthetic preference.
Finally, the Cornish language revival has produced a community of speakers and enthusiasts who take these names seriously. Resources from the Cornish Language Partnership and organizations dedicated to Kernewek can help you verify pronunciation and meaning before you commit. Getting the name right matters, and the people who care most about Cornish heritage will appreciate the effort.
Cornish names occupy a genuinely rare space: Celtic enough to feel ancient and distinctive, but tied to a specific place and tradition that most people have never explored. Whatever draws you to them, the names on this list have real roots worth knowing.
