For a long time, Isadora has been overlooked in favor of Isabella, owing perhaps to its association with the tragic modern dancer, Isadora Duncan, or because parents would rather their daughter be a Bella than a Dora. Now, with Theodora back in the charts and vintage names in vogue, Isadora has been slowly gaining more attention over the last decade.

Althea is a poetic, almost ethereal name found in Greek myth and pastoral poetry, associated in modern times with the great tennis player Althea Gibson, the first African-American to win at Wimbledon.

This is a charming name that rose steeply along with other-belle names, such as Isabelle, until the horror film Annabelle and its sequels knocked it out of favor. Made famous by the Edgar Allen Poe poem Annabel Lee. Annabelle is saucy and stylish, a tad upscale, has a sense of humor, is melodious and lively, but is unfortunately off its peak.

Isaiah, like brethren Isaac and Elijah, is a once neglected biblical name now firmly back in favor, already surpassing such long-popular Old Testament stalwarts as Aaron and Adam. Isaiah has ranked on the US Top 1000 list for boys every year but two, 1969 and 1970.

Alec, though an old nickname for Alexander, is much fresher sounding than Alex, with the additional advantage, at least to some parents, of being distinctly male (there are as many girl Alexes these days as there are boys). While Alec has a clipped British image, it's actually one of the classic Greek names for boys, by way of father name Alexander.

This Welsh nature name that can be pronounced exactly like the male Ira. Or, to avoid confusion, you could just name her Snow.

The poetic, soft-spoken Auden has recently started to be considered as a first name option, used for both sexes, appreciated for its pleasing sound as well as its link to the distinguished modern Anglo-American poet W.H. Auden.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

Crisp and colorful, Autumn is the most popular season name in the US — the only one in the Top 100 in recent years — though Summer and Winter don't rank too far behind. Cool and gentle at the same time, it also ranks highly in England and Wales.

This Biblical name was rising dramatically for boys, but has plateaued in recent years. Although it's more popular for girls in the US, it's a delightful unisex choice. Eden is one of the Top 100 Boy Names in France, closing in on the Top 10.

Aveline is a name that's long been an obscure cousin of more widely-used choices, but may come into its own riding the tail of the megapopular Ava, which may derive from the same root.

This lovely name is best-known as the surname of eponymous Bronte heroine, Jane Eyre, and would make an appealing and distinctive middle name for the child of fans of that book. While the surname Eyre is found mainly in England, its origins are Norse and it's thought to derive from Norse settlers. Still, the status of the classic books means Eyre deserves to stand proudly among English baby names.

Inara is an appealing choice with multiple origins, currently in the Top 500 in the UK and the Netherlands. Gentle looking but bright in feel, it is also on the rise in the US, possibly owing to its use in Joss Whedon's hit sci-fi series Firefly, featuring main character, Inara Serra.

Aurelian is an ancient name gaining contemporary visibility along with many other forms of the Ancient Roman Aurelius, including Aurelia and Aurelio.

Eulalia is a melodious name with a southern drawl, thanks to those lilting double Ls and similarity to similar Eudora and Eula. Familiar in the US in the early 20th century, it was also a popular choice in Brazil and Spain until the 60s when it fell out of style.

Isa is a name unto itself as both a Persian name meaning "strong-willed" and as Germanic one derived from the element is meaning "ice".

Currently popular in Brazil and The Netherlands, it has seen some increased use in the US in recent years, perhaps owing to the popularity of other short names like Ava, Mia, and Isla.

Acacia is an attractive, rarely used Greek flower name enhanced by its popular beginning-and-ending-with 'a'-construct, and is gradually beginning to catch on as a new member of the stylish girl names starting with A.
