RELATED:
- Eluned
Origin:
WelshMeaning:
"idol, image"Description:
Romantic and mysterious, Eluned's beauty and intelligence were legendary in Welsh legend; she was the handmaiden of the Lady of the Fountain in a Welsh Arthurian romance, who had a magic ring that made the wearer invisible. Pronunciation is usually similar in emphasis to Eleanor, but with ned instead of nor at the end. However, it's sometimes also pronounced el-LIN-ed or even shortened to Luned, the sounce of Lynette, in Tennyson's Gareth and Lynette.
- Endellion
Origin:
Cornish place and saint's nameMeaning:
"fire soul"Description:
Endellion is the name of an early saint who was a daughter of King Brychan and goddaughter of King Arthur whose life is commemorated by the Cornish village of St. Endellion. This intriguing ancient name was brought into modern usage by British Prime Minister David Cameron, who used it as one of the middle names for his fourth child, a baby girl.
- Ianthe
Origin:
GreekMeaning:
"purple flower"Description:
Like Violet, Lavender and Lilac, Ianthe is a purple flower name. Chosen by the poet Shelley for his daughter, Ianthe has a poetic, romantic, almost ethereal quality. In the ancient myth, she was the daughter of Oceanus, supreme ruler of the sea, and also a Cretan woman so beautiful that when she died the Gods made purple flowers grow around her grave.
- Thessaly
Origin:
Greek, place name, meaning unknownDescription:
The name of an area in northern Greece, known in the era of Homer's Odyssey as Aeolia, Thessaly makes a spirited and pretty place name. Reminiscent of Tessa, Rosalie, and Thea, the name likely derives from that of an ancient tribe, though the exact meaning isn't known.
- Kerensa
Origin:
CornishMeaning:
"love"Description:
Kerensa, forever romantic, is a rare Cornish name spelled with an 's' or 'z', the most modern of the Karen family. Kerensa (or Kerenza) has ties to the Welsh Cerys.
- Desdemona
Origin:
GreekMeaning:
"ill-starred"Description:
Desdemona is as Shakespearean as a name can be, but because the beautiful and innocent wife of Othello came to such a tragic end, her name has been avoided for centuries. But at this point in time, there might be some adventurous parents willing to overlook that.
- Pomona
Origin:
LatinMeaning:
"apple"Description:
This name of the Roman goddess of fruit trees is also associated with a suburban town in Southern California.
- Zephyrine
Origin:
Feminine variation of Zephyr, GreekMeaning:
"west wind"Description:
Zephyr may not be a name often heard in the U.S., but its variations are used throughout Europe. Zephyrine, a cousin in sound and feel if not in fact to such lovely names as Severine and Seraphina, has distinctive possibilities.
- Aphra
Origin:
Hebrew, variation of AphrahMeaning:
"dust"Description:
Aphra would make an interesting choice-- especially since it's the name of the first professional female writer in English, the seventeenth century's Aphra Behn. Born in 1640, she was a prolific dramatist of the English Restoration, and a spy.
- Cia
Origin:
English or Swedish diminutive of Cynthia, Greek, or Cecilia, LatinMeaning:
"moon goddess, woman from Kynthos; blind"Description:
What's Cia short for? Cynthia or most any other C-name. Stylish in its sleek Mia-Nia minimalist feel, but may remind some of the Central Intelligence Agency.
- Delphi
Origin:
Greek place nameMeaning:
"of Delphi; womb"Description:
An interesting unisex possibility, with an air of mystery connected to the Delphic Oracle, the most important oracle in ancient Greece; it was also a major site for the worship of the god Apollo.
- Pomeline
Origin:
French, related to "apple"Meaning:
"apple"Description:
A rarely heard--even in France--name, most prominent as the third name of Charlotte Marie Pomeline Casiraghi, the daughter of Princess Caroline of Monaco and granddaughter of Grace Kelly.
- Caro
Origin:
Diminuitve of Carol or Caroline, English, French ,"free man"Meaning:
"free man"Description:
Upper-crusty nickname occasionally used in Britain, particularly in 1930s novels featuring significant garden party scenes, but eclipsed here by Carrie et al.
- Ottoline
Origin:
French and English, diminutive of OttolieMeaning:
"prospers in battle"Description:
Curiously appealing, in a hoop-skirted, wasp-waisted way, Ottoline has recently entered the realm of modern possibility, especially since Sienna Miller chose it as the middle name of her daughter Marlowe.
- Mabli
Origin:
WelshMeaning:
"loveable"Description:
Mabli is the sweet Welsh variant of Mabel, first used at the beginning of the 20th-century making it a relatively modern choice. Cute but energetic with the appeal of other Welsh names like Cadi and Lowri, it has been in the England and Wales Top 1000 since 2019.
- Nephele
Origin:
GreekMeaning:
"cloudy"Description:
An enchanting ancient Greek name belonging to the Greek goddess who was created from a cloud by Zeus and so became goddess of the clouds and mother of the centaurs. The name Nephele is not widely known but as among modern parents become used to Phoebe, Penelope, and Persephone, it may become one of the ancient Greek goddess names that's back in the mix.
- Melisande
Origin:
French form of Millicent, GermanMeaning:
"strong in work"Description:
This old-time fairy tale name is rarely heard in the modern English-speaking world, but it's so, well, mellifluous, that it would make a lovely choice for a twenty-first century girl--a romanticized tribute to an Aunt Melissa or Melanie.
- Gwyneira
Origin:
WelshMeaning:
"white snow"Description:
An unusual Gwyn name with a lovely meaning, this compound name pairs Gwyn with the name Eira, meaning "snow". A relatively modern creation, it remains very rare.
- Bluebell
Origin:
Flower name from EnglishMeaning:
"blue bell"Description:
Bluebell is one flower name that is used very quietly. Geri "Ginger Spice" Halliwell joined her former Spice Sisters in creative baby-naming with this adventurous — some might say outlandish — choice. Andie MacDowell has a granddaughter named Bluebell Coyote through her daughter Rainey Qualley.
- Cerelia
Origin:
LatinMeaning:
"relating to springtime"Description:
Cerelia is a melodic and unusual choice, perfect for a child born in April or May. Another version is Cerella.
