Like Joanne and Christine, middle-aged Diane has been overshadowed by the a-ending version of her name. Diane has a definite mid-century feel; it was a Top 20 name from 1946 to 1959. Though it has several distinguished bearers, including Dianes Sawyer, Keaton, von Furstenberg, Lane, Arbus, Kruger and Farr, it fell off the Top 1000 in 2004 and last year was given to about 60 baby girls, the same number as Dillon and Eugenia.

Nimue (Lady of the Lake) is the ruler of Avalon in the Arthurian legend. Nimue plays a pivotal role in many stories, including giving King Arthur his sword Excalibur, enchanting Merlin, and raising Lancelot after the death of his father.

Remus is one of the legendary twins who, with brother Romulus, founded Rome. An unusual yet classic name for the extremely adventurous who can put aside the stereotyped image of Uncle Remus. Though because of that "ream" first syllable, we prefer Romulus.

Jethro, though the biblical father-in-law of Moses, has suffered for a long time from a Beverly Hillbilly image, but some really adventurous parents might consider updating and urbanizing it and transitioning it into the hip o-ending category.

Combining the mild and the innocent, this sweet and feminine name is worthy of a comeback, in the mode of Madeline and Cecilia. Its original, also attractive form is Melisende, which came from Germany to France and was borne by a daughter of Charlemagne.

One of the stellar unique baby names from mythology, Andromeda was the beautiful daughter of Cassiopeia who, like her mother, literally became a star--the constellation that bears her name.The Bohemian Andromeda makes a dramatic and adventurous choice in a time when four-syllable mythological names are gradually making their way into the mainstream.

A soft and interesting Hebrew name long popular in France, where it has ranked in the Top 400 since 1986 (as Salomé). Ex-ER star Alex Kingston named her daughter Salome Violetta.

Drusilla is an ancient Roman name, (probably) borne by descendants of Antony and Cleopatra, and is one of the 'illa' names that are ready for a comeback, especially with its cute short form Dru.

Acacius is a Latinized form of the Ancient Greek Akakios and can be interpreted to relate to the same root as the name Acacia, for the thorn bush, or Akakios which means "not evil." With the modern taste for ancient names that end in "us," this obscure but attractive choice may have a chance of new life. Acacius is the name of three early saints.

This name of a Roman emperor and of a sedating plant is still used quietly, given to about a dozen baby boys in the US last year. It has a strong, rhythmic sound and could make a modern-feeling honor name for grandma Valerie.

The name of an important ancient Roman emperor, Tiberius might sound a bit heavy for a modern boy to carry, but with the rise of Atticus, Tiberius and brothers begin to feel more baby-friendly, much in the same way as Old Testament names like Elijah and Isaiah have been rejuvenated.

Oisin is one of the most popular Irish baby names in its native land, though largely unknown in the US. The original Oisin was the mythological son of Finn McCool and Sadb, the goddess who was changed into a deer. A legendary war hero and poet, Oisin had a name that is also reminiscent in sound of the ocean. Pronounced correctly, this name has an attractive sheen.

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.

Erasmus has long retained the image of the bearded and bespectacled Dutch philosopher, but could be one that the audacious baby namer just might dare to dust off.

Hermione's costarring role in Harry Potter has made this previously ignored, once stodgy name suddenly viable. Hermione could really take off once today's children start having kids of their own.

Brutus is the quintessential brute--far too close to the word brutal. And any child with this name would spend much of his life hearing "Et tu."

This evocative name of one of the Three Wise Men of the Orient, also spelled Balthasar, may finally be ready for prime time. Balthazar, Melchior and Caspar were the Magi who brought gifts of gold, frankincense and myrrh to the baby Jesus, though their names were not mentioned in the Bible.

Ferelith is an unusual yet deeply-rooted Scottish girl's name, also found in ancient Ireland and drawn from the Gaelic Forbhlaith or Forbflaith. While it went through a period of dormancy after the Middle Ages, there are some modern women named Ferelith, including actress Ferelith Young and Princess of Denmark Anne Ferelith Fenella Bowes-Lyon.

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

Xochitl is a Nahuatl or Aztec floral name used in southern Mexico and pronounced SO-chee-tl or SHO-chee-tl, although sometimes the "tl" at the end is not pronounced. Internet entrepreneur Xochi Birch is probably the best-known bearer in the US – except for the Xochitl brand tortilla chips. Definitely among the most intriguing international flower names and a beautiful choice for those looking to honor Nahuatl heritage.
