The name of the great Homeric hero with the vulnerable heel, Achilles is more popular in its international form, Achille, which is popular in France, Italy, and Belgium. This variation did however appear briefly on the US Top 1000 list in 2015, perhaps owing to its similarity to the likes of Atticus, Adonis, and Apollo. It has declined in use since then, but is nevertheless chosen for around 160 babies each year.
 
In Greek Mythology, Achilles was the name of a warrior, who fought against the Trojans, making it a strong feeling choice. Borne by several early saints, its exact meaning is unknown, though it might derive from the Greek achos, giving it the meaning "he whose people have distress and pain". Other theories suggest that it's a name with a double meaning - combining kleos "glory" with the idea of pain and distress. 
 
Madeline Miller's popular novel, The Song of Achilles, which focuses on the relationship between Achilles and Patroclus, has likely shone the name in a new light and may account for some of its increased popularity.
 
The 'KIL' syllable might put people off, but that hasn't been a problem for Killian in recent years.

Achilles

The Native American name for Martha's Vineyard and for a town at the far end of that lovely island, this was used by Michael J. Fox and Tracy Pollan for one of their twin daughters. 

Aquinnah

The name of medieval French saint, similar to Sally Field's name, Bertrille, on the old The Flying Nun sitcom, leading some to expect the word "Sister" in front of it.

This genial Irish surname feels much more current than Donald.

Though Eoin is a Gaelic form of John, its Anglicized pronunciation links it directly to Owen. Eoin is currently a Top 30 name in Ireland. Other variations: Ewan, Ewen, Evan and Eoghan (pronounced as Owen but also translated as Eugene).

Eugene is a classic that has rather lost its way. On the one hand, it's a grandpa, even great-grandpa name that hasn't been one of the cool kids recently—or to quote Jim Carrey, who bears this name in the middle spot, "You can never get too cool with a name like Eugene." The hero of Disney's Tangled felt the same way, when he changed his birth name of Eugene to the more romantic Flynn.
 And yet! Eugene has had a long history of popularity, as a Top 50 name from 1880 to the 1940s. In fact, it has never been out of the Top 1000, making it a classic that's still given to hundreds of boys each year. It's even stopped falling in the last few years, and we could speculate that one day it will return to style.
 Also on the plus side, there were four popes and several saints named Eugene. A literary namesake is playwright Eugene O'Neill, and in art history Eugene Delacroix. In addition, there is the classic Russian novel by Pushkin, Eugene Onegin, and Eugene is the name Neil Simon used for his stand-in in three autobiographical plays, starting with Brighton Beach Memoirs.
 The female form, Eugenie, is chic and elegant, belonging to one of the daughters of the Duke and Duchess of York.

Eugene

Ancient martyr's name that, though not especially appealing, might still be mildly possible, especially for Anglophiles. It was widely used in early Scotland, but was overtaken by its nickname, Effie.

Euphemia

This appealing name has a good chance of catching on due to the popularity of Ewan McGregor, and the trend towards Gaelic names in general. Pronunciation is YOO-un.
 Ewan has a complex family tree, with connections to John, Owen, Hugh, Evan and Eugene. Other spellings are Ewen, Eoin and Euan.
 In Willa Cather's novel My Mortal Enemy, there is a character called Ewan Gray.

Ewan

One you might like for its cozy meaning, but there is that Pied Piper rat connection.

Iliana is one of the vaguely but usually undefinably international names that have a wide range of spellings and pronunciations. Ilium was the poetic name of the city of Troy, and variations of this name — especially Ileana and Ileanna — have been widely used, projecting a rather bohemian image. The traditional Greek pronunciation would be ee-lee-AH-nah while in English speaking countries, it might be ill-ee-AH-nah.

Iliana

Leda is that rare name that has not yet been discovered in the current craze for ancient names from mythology.  In classical Greek myth, Leda was a great beauty who mothered another great beauty, Helen of Troy. 

Leda is at once simple, deeply-rooted, and unique: Only 23 baby girls were named Leda in the US last year. A name used in several European countries, pronunciation is usually the straightforward lee-dah but the Italians say lay-dah.

Leda

Leta has hipster cred as the daughter of cool mommy blogger Dooce. Related to the Greek mythological Leda, a great beauty who mothered another great beauty, Helen of Troy, Leta is a name that's as unique as it is historic: Only 14 baby girls were named Leta in the US last year, and 18 were named Leda. Pronunciation is lee-tah.

Leta

Lucasta was invented by seventeenth century poet Richard Lovelace for a collection of poems dedicated to a lover named Lucy, and is familiar through the Eugene O'Neill play and film Anna Lucasta. Lucasta is a distinctive, rarely used choice and a logical extension of the Luke/Luc/Luca names.

The name of our first First Lady still has something of a prim and proper image, academic and efficient. That quiet, traditional, and tasteful gestalt is exactly what makes Martha appealing to some parents today.
 The New Testament Martha, sister of Lazarus and Mary of Bethany, was a solicitous housekeeper who looked after the material welfare of Jesus when he was a guest in her home. For this reason Martha has since been identified with domestic labor and hospitality and is the patron saint of housewives, waiters, and cooks (a la Martha Stewart, who shares her name with her mother).
 Martha has been a royal name in Scandinavia, the subject of Beatles song "Martha My Dear," and is also associated with the New England island Martha's Vineyard. Livelier foreign forms that have been used in this country include Marta, Martine, and Martina.
 Modern dancer/choreographer Martha Graham would make a notable namesake for a dance aficionado.

Though most Mels are playing pinochle with Murray and Morris, there was a notable Saint Mel. He is one of the earliest Irish saints, a nephew of St. Patrick.  He became a  priest, then built a great monastery where he served as abbot.

Melker, a modern phonetic spelling of ancient Three Wise Men name Melchior, is in the Swedish Top 100 though not used in the US, where it would be heard as "milker."  Nickname Mel is not exactly a fashionable choice at the moment either.

The oldest-known form of Mary, serious and solemn Miriam has been a particular favorite of observant Jewish parents. But we can see it extending beyond that sphere into the next wave of Old Testament names post-Rachel, Rebecca, Sarah, Hannah, and Leah. Miriam is currently the Number 1 girls' name in Israel.
 Miriam is the Old Testament form of the Hebrew Maryam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).
 In the Old Testament, Miriam appears in Exodus as the older sister of Moses and Aaron, a prophetess who led the triumphal song and dance after the crossing of the Red Sea and deliverance of the Israelites from the Egyptians.
 Miriam is an artistic character in Nathaniel Hawthorne's The Marble Faun and in Henry James's The Tragic Muse, Miriam Rooth is a talented young half-Jewish actress, Miriam Leviers is a farm girl in D. H. Lawrence's Sons and Lovers, and Miriam is the eponymous central character of a haunting Truman Capote short story.
 One notable namesake is South African singer Miriam Makeba. More relaxed nicknames: Miri, Mira, and Mimi.

Miriam

The Dutch name is usually spelled Myrthe or Mirthe and pronounced meer-ta.  But most English speakers will say it mer-tha and confuse the name with Martha, Bertha, or Myrtle.

Mirtha

Soft and sensitive name often heard in Israel. 

Oren

Orin is one of a variety of similarly-spelled names that have a soft and sensitive image. The Orrin spelling has been known nationally via Republican Senator Hatch.
 Orin is the name of a character in Eugene O'Neill's drama Mourning Becomes Electra. Oren is a Hebrew name that means laurel while Oran is Irish and means pale little green one.

Orin

Tamlane is a variation of Tam Lin, a (male) character in an old Scottish legend and ballad. Tam Lin was imprisoned by the Queen of the Fairies, called Titania or Mab.

While this name is sometimes given as a variation of Thomas, that is false. Tam Lin is also found as Tamlane, Tamlin, Tambling, Tomlin, Tam Lien, Tam-a-Line, Tam Lyn, or Tam Lane.

Tamlane

A second-tier classic, the New Testament Timothy moves in and out of fashion more than John and James. But though it peaked in the 1960s, many modern parents still appreciate its familiarity and lively rhythm. And the short form Tim feels eternally boyish.
 Saint Timothy, born of a Jewish mother and a Greek father, was Saint Paul's companion, which might make the two appropriate and compatible <a href="https://nameberry.com/blog/twin-names-the-ultimate-guide">twin names</a>. Timothy was well used among early Christians but not popular in the English-speaking world until the eighteenth century. In the U.S., Timothy was just outside the Top 10 in the 1960s and stayed in the Top 100 until 2008.
 In literature, there is the unforgettable Timothy Cratchit, aka Tiny Tim. In real life, there are director Tim Burton and several well-known actors, as well as a slew of star athletes.
Timothy also qualifies as a botanical name thanks to Timothy grass sometimes known simply as Timothy, which resembles cat's-tail and is used as cattle feed.

Timothy

Troy shot to popularity as a first name in tandem with that of 1960s heartthrob Troy (born Merle) Donahue; its image has now, thanks in part to the Brad Pitt-starring epic, Troy, receded back to conjuring up the ancient site of the Trojan wars.

The name of a martyred medieval saint, Valerie has been on the popularity list since its earliest publication in 1880. Though it peaked in the 1960s, remaining in the Top 100 until 1988, it still doesn't sound terminally dated; the association with the word valor gives it a sense of boldness and makes it one of the special group of <a href="https://nameberry.com/list/96/girl-names-that-mean-brave-or-powerful">girl names that mean strong</a>. 
 The original name Valeria, came into use in the 1890s, followed soon after by the French form Valerie, which rapidly became the more accepted form. In the 2011 werewolf update of Red Riding Hood, Red was given the name Valerie.

Valerie

This name of the major Maltese city takes on an air of attractiveness via model Amber Valletta, making it an appealing alternative to the overexposed Valerie and Vanessa.
