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.
- Kirrily
Origin:
Aboriginal, AustralianMeaning:
"tree bark or leaf"Description:
Kirrily, which rhymes with cheerily, is a name that's uniquely popular in Australia. It originated in recent decades as an elaboration of several similar names – the European Kyra or Keira, the Maori Kiri which means tree bark, or the Aboriginal word kira which means leaf – plus the lee sound.
- 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.
- 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.
- 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.
- 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.
- Plum
Origin:
Fruit nameDescription:
British-born novelist Plum Sykes has taken this rich, fruity name out of the produce section and put it into the baby name basket. It's more appealing than Apple, more presentable than Peaches. The French equivalent, Prune, is very fashionable there but would not fly with English speakers.
- Mabli
Origin:
WelshMeaning:
"lovable"Description:
Mabli is the sweet Welsh form of Mabel; like its English cousin, it’s starting to make a modest comeback in Wales as part of the trend for vintage baby names from a century ago.
- 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.
- 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.
- Liliosa
Origin:
SpanishMeaning:
"lily"Description:
Liliosa, one of the most extravagant forms of the ever-more-popular and varied Lily family, is an ancient saint's name that's a perfect candidate for revival by parents who love the double-L flower name trend but want a distinctive variation. Saint Liliosa was one of the martyrs of 9th century Cordoba, along with her husband Felix and cousins Aurelius and Natalia — all names newly fashionable in the modern world.
- 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.
- 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.
- Malou
Origin:
Combination of Mary and LouMeaning:
"bitter; renowned warrior"Description:
This charming name, popular in France and the Netherlands, has not traveled to the U.S. yet but would make a modern way to honor grandma Mary or Louise, or as a perfect short form of Mary Louise. Or, with the growing fashion for nickname names, it can stand perfect well on its own. One of several similar variations — Lou, Lilou, Louane — in vogue in Europe.
- 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.
- 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.
- 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.
- 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.
- 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.
