Ebenezar

Creative gem perfect for an architect's son, in tribute to modern Finnish-American architect Eero Saarinen. 

Eero

Long popular in Scotland, this attractive name is strictly-speaking the Gaelic version of Eleanor, but is also often considered part of the Helen family of names. After the Normans introduced it into the British Isles, it was transformed into Aileen or Evelyn. It has rarely been heard in the US, but it is slowly starting to be used here too.

Eilidh

Eleazar is a distinguished Biblical name--in which it appears several times-- ripe for the picking following the stardom of Eli, Elijah, and other similar names. 
 Eleazar is also a Twilight name, first appearing in the Stephenie Meyers book Breaking Dawn.
 It's related most closely to Eliezer, which also appears in the Bible many times. The name also belonged to three great Talmudic scholars.

Eleazar

The lyrical and melodious Elodie, a Nameberry favorite, is starting to rise through the US popularity charts for the first time since the 1880s. It's a uncommon member of the trending El- family of names, which includes Ella, Eloise, and Eleanor. 
 
Elodie derives from Elodia, the Spanish variation of Alodia, a gothic German name associated with Saint Alodia. Saint Alodia was a child martyr in 9th century Spain, along with her sister Nunilo. In France, Elodie is spelled Élodie, with an accent over the E.
 
Élodie is a mono-named Italian singer and model as well as a major character in the Emile Zola novel The Earth. Princess Elodie is the protagonist of the video game Long Live The Queen and there was a character on The Hills named Elodie.
 Popular in the UK and French-speaking countries, Elodie could make an original honor name for Aunt Melody.

Before there was the campy TV Elvira, Mistress of the Dark, Elvira was the long-suffering wife of Don Juan, and remnants of those negative, gothic images still cling to it, though they are fading.
Other references include the romantic film Elvira Madigan, based on a real person, and the main ghostly character in Noel Coward's Blithe Spirit, as well as appearances in several operas.
 Elvira was in common use in the US in the late nineteenth and early twentieth centuries, remaining in the Top 1000 until 1981; it's still popular in Scandinavia, ranking Number 39 in Sweden.

Elvira

Unlike Amber, which is in decline, this name still has a bit of a glow left -- though confusions between the two will inevitably arise.

Ember entered the Top 1000 in 2009 and has risen steadily in the years since. The Em beginning can make it an original route to the nickname Emmy.

Ember

Emmeline is an Emma relative and Emily cousin that is destined for greater use in the wake of the megapopularity of those two names. A recommended Nameberry fave, Emmeline hopped onto the US Top 1000 in 2014 for the first time ever. While it is genuinely an old name, it was rarely used a century ago; only 17 baby girls were named Emmeline in 1915, the same number as were named Ernie!
 A popular medieval name, Emmeline was introduced to Britain by the Normans. It appeared as a character in Uncle Tom's Cabin, and is famous in Britain as the name of the illustrious suffragette, Emmeline Pankhurst. Way back in 1980, it was the name of young Brooke Shields's innocent character in The Blue Lagoon. More recently, Emmeline Vance was a witch in the Harry Potter series.
 Christian Bale has a daughter named Emmeline.

Emmeline

Less popular than Emery, this name also attributes to Emory University. Both spellings of the name lean more heavily to the girls' side, but this one is not quite as unbalanced.

Emory is used about 40 percent of the time for baby boys, while with Emery, it's only a bit over 10 percent.

Enna

Enola was a precursor of Nevaeh: It's "alone" spelled backwards. But the name Enola is newly in the spotlight thanks to a Netflix film.

For decades, Enola was known only as the name of the plane that dropped the atomic bomb on Hiroshima, Enola Gay. Not very positive.

More recently, Enola has achieved some notice as the name of Sherlock Holmes' (fictional) younger sister, not a character in the original books by Arthur Conan Doyle but in the series by Nancy Springer, now a film on Netflix. This may make Enola a name worth consideration.

Enola

Eponine is attracting new notice via the movie of Les Miserables, based on the book by Victor Hugo.  Eponine is the spoiled daughter of Cosette's foster parents whose name, according to the story, was lifted by her mother from a romance novel.  As in a romance, Eponine redeems herself by becoming a martyr to love.

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

Evangeline is a romantic old name enjoying a major comeback, thanks to its religious overtones, Eva's popularity, and the star of the TV megahit Lost, Evangeline Lilly. Evangelia and Evangelina — two variants of Evangeline — are sure to tag along for the ride.

 Evangeline was introduced to the English-speaking world by Longfellow in his hugely popular eponymous narrative poem, and can also be found in Uncle Tom's Cabin (it was Little Eva's full name), as well as two novels by Evelyn Waugh. More recently, there were Evangelines in the films Nanny McPhee and Disney's The Princess and the Frog.
