Rare girl names you’ll hear once
A genuinely rare girl name is one given to fewer than a few hundred babies a year — rare enough that your daughter will almost certainly be the only one in her school. Below are 20 that meet that bar and still have real history behind them, with meanings, nicknames, and an honest note on what each one costs day to day.
Rare is a slippery word in baby-name writing. Lists routinely call a name rare while it sits inside the top three hundred, which means several thousand babies a year and probably one in your daughter’s year group. The names here are further down than that, and where one has been climbing I have said so rather than quietly leaving it in.
Every name below is documented — in saints’ calendars, in registers, in literature. None is invented, and none is a respelling of something popular. A respelling buys you the correction without the history, which is the worst of both.
There is a real cost to a rare name, and it is not social. It is the small administrative friction of spelling it at every appointment for eighty years. For some names here that cost is nearly nothing. For others it is significant, and it is named.
The list
Verity
Truth · Latin. A virtue name that escaped the Puritan heaviness of Patience and Prudence. Nickname: Vera, Vee. Caveat: virtue names invite comment about whether the child lives up to them. Style note: Vee is a clean, modern short form.
Sunniva
Sun gift · Norse. A Norwegian saint with the loveliest meaning on this list. Nickname: Sunny, Niva. Caveat: unfamiliar outside Scandinavia and will be misheard as Sonia. Style note: Sunny makes it instantly warm.
Ilaria
Cheerful · Italian, from Latin Hilarius. The Italian form of Hilary, and far prettier than the English version. Nickname: Lari, Ila. Caveat: the ee-LAH-ree-a pronunciation is not obvious to English speakers. Style note: shares a root with the word hilarious.
Perpetua
Continuous; everlasting · Latin. An early Christian martyr with a name that is pure Roman stone. Nickname: Petra, Pet, Tua. Caveat: genuinely a lot of name — four syllables and an unusual shape. Style note: works better as a middle name for most families.
Maren
Of the sea · Danish, from Marina. Short, clean, and the sea meaning without the frill of Marina. Nickname: none needed. Caveat: competes with Marin and Maren spellings. Style note: the easiest name to live with on this list.
Thomasin
Twin; the feminine of Thomas · Aramaic, via English. A genuine medieval English name that simply stopped being used. Nickname: Tamsin, Tam, Tommie. Caveat: Tamsin is the better-known form. Style note: choose whichever of the two you actually want said.
Oriane
Golden; dawn · French, from Latin. French, silvery, and almost unused in English-speaking countries. Nickname: Ori, Anne. Caveat: pronunciation splits between the French and English readings. Style note: Ori is a strong, current-sounding short form.
Constance
Steadfast · Latin. An old virtue name that has been out of fashion long enough to sound new again. Nickname: Connie. Caveat: Connie is much warmer than Constance and will win. Style note: that is not a bad outcome.
Elowen
Elm tree · Cornish. A modern Cornish name, and one of the few recent coinages with a real language behind it. Nickname: Elo, Ellie, Wen. Caveat: Ellie pulls it toward the most popular girls’ name of the decade. Style note: I have flagged that it is modern rather than ancient.
Sabine
A Sabine woman · Latin. Roman, cool and slightly severe, with a history that is worth reading. Nickname: Bina, Sabby. Caveat: the Sabine story is not a gentle one. Style note: sa-BEEN in French, sa-BY-nuh in German — pick one.
Cecily
Blind · Latin. The medieval English form of Cecilia, and the unflattering meaning has never held it back. Nickname: Cece, Sissy. Caveat: the literal meaning bothers some parents. Style note: Cecilia is the patron saint of music, which softens it.
Hesper
Evening star · Greek. The evening star, and a name almost nobody has taken. Nickname: Hess, Hettie. Caveat: sounds close to the word whisper, which is either charming or annoying. Style note: Hesperus is the full Greek form if you want more.
Rosamund
Horse protector, though popularly read as rose of the world · Germanic. Two competing etymologies, and the romantic one is the wrong one — I have given both. Nickname: Rosa, Ros, Mundy. Caveat: long. Style note: Rosa is far more common than Rosamund.
Fenella
White shoulder · Scottish Gaelic, from Fionnghuala. The anglicised Scottish form, and a genuinely uncommon one. Nickname: Nell, Fen. Caveat: Nell is having a moment and may overtake it. Style note: Fen is an unexpectedly modern short form.
Marguerite
Pearl; also the daisy · French, from Greek. A pearl and a flower at once, and much less used than Margaret. Nickname: Daisy, Maggie, Rita. Caveat: four syllables in English. Style note: Daisy as a nickname is a lovely, non-obvious route in.
Isadora
Gift of Isis · Greek. An Egyptian goddess inside a Greek name, and a famous dancer behind it. Nickname: Izzy, Dora, Sadie. Caveat: Izzy and Sadie are both far more popular than Isadora. Style note: Sadie is the surprise short form here.
Wilhelmina
Resolute protector · Germanic. Formidable, old-fashioned in the best way, and it hides three good nicknames. Nickname: Willa, Mina, Billie. Caveat: five syllables. Style note: Willa and Billie are both strong enough to stand alone.
Solveig
Strong house; sun strength, disputed · Norse. Ibsen’s most loyal character, with a name that sounds like weather. Nickname: Sol, Vig. Caveat: pronunciation is a genuine obstacle — SOL-vay. Style note: choose it only if you are willing to teach it.
Araminta
Uncertain; a literary coinage from the 1690s · English. Invented for a play three hundred years ago, which makes it a rare thing: a coinage with real age. Nickname: Minty, Minta. Caveat: it is a coinage, and I would rather say so. Style note: Minty is the whole appeal.
Clementine
Merciful · Latin. Warm, slightly old-fashioned, and the meaning is mercy rather than fruit. Nickname: Clem, Clemmie, Tine. Caveat: the song is inescapable and so is the fruit. Style note: Clemmie is one of the best short forms in this whole list.
How to judge whether a name is really rare
Go to the actual numbers rather than trusting any list. The Social Security Administration publishes how many American babies received each name last year, and the figures routinely contradict what baby-name sites claim. A name a blog calls rare might sit at four thousand babies a year, which is one in most large schools. Genuinely rare, in the sense of your daughter being the only one she ever meets, means a few hundred a year or fewer.
Then check the direction of travel, not just the level. Elowen and Maren are both uncommon today and both climbing quickly, which means the name your daughter has at eighteen may be far more familiar than the name she has at two. Names that have been flat for decades — Perpetua, Hesper, Solveig — are the ones that will still be rare when she is grown.
Last, be honest about which cost you are paying. Every rare name charges you in one of two currencies: spelling or explaining. Maren and Verity are effortless to spell and need no explanation. Solveig and Sunniva require a small lesson every time. Neither is worse, but knowing which one you have chosen makes the next eighty years easier.
A note on sources. Popularity figures throughout are the Social Security Administration counts of US babies given each name, which is the actual registration data rather than an estimate. Meanings are checked against Behind the Name, which cites its references; where scholars genuinely disagree about an origin, both readings are given above rather than the prettier one.
Who this list doesn’t suit
If you want a rare name that never needs repeating, that name does not really exist. Rarity is unfamiliarity, and unfamiliarity means people ask. The closest you can get is a rare name built from familiar sounds — Maren, Verity, Cecily — which buys you an easy spelling at the cost of being slightly less distinctive.
It also won’t suit you if the meaning has to be beautiful. Several of the loveliest sounds here carry blunt meanings. Cecily means blind. Rosamund most likely means horse protector rather than rose of the world. Sabine refers to an episode in Roman history that no one would describe as romantic. If the etymology is going to sit badly with you later, better to know now.
And if you have other children with common names, a very rare name for this one can create an odd asymmetry in the family. A Sophie and a Perpetua sound like they were named by different people in different decades. It is not a reason to avoid it, but it is worth saying the names out loud together before deciding.
Still narrowing the shortlist? short girl names with real weight and vintage girl names cover neighbouring ground. It is also worth reading how to choose outside the top 100 and nature names for girls before you settle on anything.
FAQ
What are the rarest girl names?
From this list, Perpetua, Hesper and Solveig are the least used, each given to fewer than a hundred American babies most years. All three have documented historical use rather than being invented.
What is a rare girl name that is easy to spell?
Maren, Verity and Cecily. Each is uncommon enough to be distinctive but built from familiar English sounds, so it can be spelled correctly on the first hearing.
Are rare names bad for a child?
No, and the research on this is more reassuring than parents expect. The real cost is administrative rather than social — repeating and correcting. Most adults with rare names report minding it considerably less than their parents worried they would.
Which rare girl names are climbing in popularity?
Elowen and Maren are both rising quickly, and Clementine has climbed steadily for a decade. If you want a name that stays rare, the flat ones like Perpetua and Hesper are safer bets.
Should a rare name go first or middle?
The middle slot is a good compromise for the most demanding names. Perpetua, Solveig and Araminta all work beautifully as middle names, where they carry meaning without asking your daughter to spell them daily.
