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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Cosetta
Origin:
Italian, FrenchMeaning:
"little thing"Description:
Italianate variation of Cosette, from Victor Hugo's Les Misérables.
- Alouette
Origin:
FrenchMeaning:
"lark"Description:
Alouette is a sweet Gallic twist in the stylish bird name genre made familiar via the charming French children's song, Alouette, gentile alouette.
- 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.
- 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.
- Perdita
Origin:
LatinMeaning:
"lost"Description:
A Shakespearean invention for an abandoned baby in The Winter's Tale, Perdita's sense of loss has always been off-putting to parents. But her image was somewhat resuscitated by its association with the appealing canine character in Disney's One Hundred and One Dalmations.
- 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.
- 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.
- 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.
- 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.
- Iseult
Origin:
CelticMeaning:
"ice battle"Description:
Strong and sharp but with a pretty, poetic feel about it, Iseult appears in the world of Arthurian legend. Also written as Yseult, Ysolt, and Isolde, the name might have Germanic roots, blending is and hilt to give it the cool, wintery meaning of "ice battle".
- 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.
- Sidonie
Origin:
LatinMeaning:
"from Sidon "Description:
Sidonie is an appealing and chic French favorite that is starting to attract some American fans as a fresher alternative to Sydney. Also spelled Sidony, Sidonie was the birth name of the French novelist Colette.
- Sophronia
Origin:
GreekMeaning:
"sensible, prudent"Description:
Stately and elegant, but with the familiar sounds of Sophia and Sophie, Sophronia was a familiar choice back in the 19th century but has since fallen into obscurity. Derived from the Greek sophron, it means "sensible, self-restrained".
- Pomona
Origin:
LatinMeaning:
"apple"Description:
This name of the Roman goddess of fruit trees is also associated with a suburban town in Southern California.
