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.

Sorrel is a gentle, amber-hued herbal and autumnal name that's used most often to describe the color of a horse. Sorrell is a variant spelling. Both make excellent names for autumn babies and can be used for either gender.

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.

Brock is a rock solid name, with a touch of preppy sophistication. It ranked solidly in the 200s-300s from 1975 until 2014, but has since tumbled a bit.

Lionel is one leonine name that hasn't taken off as cousins Leo and Leonardo have, though it did reenter the Top 1000 in 2010 after several years away; it was at its highest point in the 1920s and 1930s.

Hart could be the hero of a romantic novel, but on the other hand, it's short, straightforward, and strong sounding. The most famous bearer of the name was tragic poet Hart (born Harold) Crane, but it also has musical cred via Lorenz Hart, of the classic Rodgers & Hart songwriting duo and a literary tie to playwright Moss Hart.

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. Although most people don't think of it like this, Indigo might also be considered among the most stylish Greek baby names in use today. Some cultural references: The Indigo Girls are a folk duo, 'Mood Indigo' is a classic Duke Ellington jazz composition, and there is a 1970's New Age theory that Indigo children possess special, sometimes supernatural abilities. 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.

Lowell is an upstanding and somewhat conservative name that calls to mind the genteel patrician families of nineteenth century New England, such as the one poet Robert Lowell was born into. Two other Lowell-surnamed poets are Amy and James Russell.

As Bas, it's a popular name in The Netherlands, but Baz, as in director Luhrmann, has potential for independent life too.

Curiously, Australian-born Moulin Rouge director Luhrmann was born neither Sebastian nor Basil, but had the name Mark Anthony on his birth certificate; his nickname arose from his supposed resemblance to a British TV fox puppet named Basil Brush.

The Forest variation of Forrest, used by actor Whitaker, nudges the meaning more toward the woods and away from the woodsman.

Perseus is a godly Greek hero (he was a son of Zeus) whose ancient name just might have modern possibilities along with other so-old-they're-new-again names such as Atticus and Orion.

Perrin has been in long use as a surname, derived from Peter, and is now used quietly as a first name. It may rise higher now that it's a character name in the popular TV adaptation of Robert Jordan's fantasy novel series The Wheel of Time.

With a distinctive sound and a robust feel, Laith is a name that also has a touch of breezy charm to it. Currently in the UK Top 1000, it is a cross-cultural boy name that's also on the rise in the US.

One of the fierce new animal names new to name lists, helped by its strong x-ending.

An evocative unisex one-syllable name, Poe is most distinguished by its literary reference. Edgar Allan Poe was an influential American author and poet, credited with inventing the genres of detective and science fiction, which might provide inspiration for parents who are fans. And now its choice as the name of the hero played by Oscar Isaac in the new Star Wars movie is sure to catapult it from literary choice to major favorite.

This evocative green nature name, heard much more frequently as a surname, is associated with playwright Moss Hart (born Robert), who co-wrote (with George S. Kaufman) such enduring Broadway comedies as The Man Who Came to Dinner and You Can't Take it With You.
