Aleksandra is the preferred spelling in many Eastern European languages and cultures, but for English-speakers it's ironically more confusing if also perfectly phonetically clear.

Aleksandra

The Spanish form of Andrew is popular enough in the US to rank near the Top 200. As Andrew, Andy, and Drew feel less fresh, Andres is still up-and-coming, with a global feel that could travel well anywhere.

Andres has been used in the US dating all the way back to when name data began to be kept, and has never fallen out of the Top 1000. Despite this, it has only been since the 90s that Andres has cracked the Top 200. Andre is a similar-sounding alternative that has French and Portuguese roots.

Anna has become the dominant form of the Ann family, offering a touch of the international to English speakers and a bit more style than the oversimplified Ann or Anne.
 Anna is the Latin form of Hannah, a Hebrew name that derived from root chanan, meaning "grace." European Christians embraced the name for its associations with the Virgin Mary’s mother, Saint Anna — known in English as Saint Anne.
Anna has been used for generations throughout Europe, from Russia to Italy, Spain to The Netherlands. While Hannah and Anna are the most common forms of the name, variations including Annie, Annalise, Anya, Anika, Nancy, and Anais also rank in the US Top 1000.
 
Classic and simple, Anna would be an excellent choice for parents in search of a name that will bridge two different cultures, say Jewish and Italian.
 
In literature, Anna is associated with Tolstoy's Anna Karenina. The name was given some fresh life when it was used for the adorable younger sister voiced by Kristen Bell in the animated film Frozen. Three current bearers are actresses Anna Kendrick, Anna Friel, and Anna Paquin.
 
Anya takes it more into international territory, and Anja, even further. Read more about Anna and other <a href="https://nameberry.com/blog/disney-princess-names">Disney Princess Names</a> in our featured blog.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.
An airier and more elegant version of Helen, Helena was a favorite of Shakespeare, who used it in both All's Well That Ends Well and A Midsummer's Night Dream. 

Historically, Helena was the mother of Constantine the Great (and, supposedly, the daughter of Old King Cole), who became a fourth century saint--Evelyn Waugh wrote his only historical novel, Helena, based on her story.
 British star Helena Bonham Carter and Danish model Helena Christensen have done much to keep the name alive, and it is also remembered via beauty mogul Helena Rubinstein. Helena is also the title of a song by the group My Chemical Romance.
 Helena is a recommended <a href="https://nameberry.com/girls-names">girls' name</a> for those who find the classic version a bit bland.
 HELL-ehn-a is the best modern pronunciation for Helena, but hell-AYN-a or even hell-EEN-a work too.

Johanna is the version of this name used in Holland, Germany, and Scandinavia. The extra h makes Johanna a slightly more dignified version of Joanna. 
 A notable namesake is the author of Heidi, Johanna Spyri. There are Johannas in Sweeney Todd, The Hunger Games, and the Bob Dylan song, "Visions of Johanna."

Lainey is one of the many fast-rising nickname names of the last few years, and longer forms like Elaine, Alaina, and Delaney are enjoying their own bouts of popularity. Simple and tailored, but equally sweet Laine is not yet in the Top 1000, but feels stylish today.

Laura is a hauntingly evocative perennial, never trendy, never dated, feminine without being fussy, with literary links stretching back to Dante. All this makes Laura a more solid choice than any of its more decorative counterparts and one of the most classic <a href="https://nameberry.com/search/girls-names/l">girl names starting with L</a>. 
 Laura has ranked on the <a href="https://nameberry.com/popular-names">popular names</a> list since official US records have been kept. A frequent Top 20 name from 1963 to 1986, reaching Number 10 in 1969, Laura remained in the Top 100—minus a brief stretch from 1935 to 1944—until as recently as 2001. 
 The meaning of the name, laurel, implies victory via the laurel wreath worn by Olympic athletes and Roman emperors. It was first made famous by the Laura to whom the Italian Renaissance poet Petrarch dedicated many of his love poems and was later used by Dickens in Bleak House.
 Well known Lauras include First Lady Bush, Little House writer Ingalls Wilder, designer Ashley, and actors Dern and Linney.

Leena is the form of Lena found in Finland and Estonia. It sits just outside the Top 1000 in the US, where it may be used as a Lena alternative that avoids pronunciation confusion.

Mari enjoyed some mid-century popularity as a nicknameish version of Mary, but now deserves a second look as a multicultural classic. Mari is the name of the Basque goddess of fertility and weather and is also, for unrelated reasons, popular in Norway. The biggest problem with the potentially-lovely Mari will be getting people to say it the way you want. While some Europeans pronounce it as Marie, that will only confuse things more. Better to make it its own individual name by pronouncing it MAH-ree. As one commenter pointed out, in Estonian the name is not a Mary variation but means "berry" – all the more reason for us to like it!

 The meaning of Mary 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).

Oliver is an international star, ranking near the top of the charts in the US and throughout the English-speaking world, along with a host of European and Latin American countries, from Norway to Chile, Slovenia to Switzerland.
 
Long a popular choice in England, Australia and New Zealand, Oliver entered the list of Top 100 <a href="https://nameberry.com/boys-names">baby boy names</a> in the U.S. for the first time in 2009, but has already jumped to the top of the charts. Why? Because Oliver is energetic and good-natured, stylish but classic, with a meaning symbolizing peace and fruitfulness. 
 
Oliver derives from Olivier, the Norman French variation of the Ancient Germanic name Alfihar ("elf army") or the Old Norse Áleifr ("ancestor's relic"), from which comes Olaf. Olivier emerged as the dominant spelling for its associations with the Latin word oliva, meaning "olive tree."

Oliver was used as a given name in medieval England after the spread of the French epic poem ‘La Chanson de Roland,’ which features a character named Olivier. It lost favor after the seventeenth century rule of Oliver Cromwell, then was revived in the nineteenth century. 

Oliver's biggest boost in this country came from the hit book and movie Love Story, which also catapulted the name Jennifer to stardom. Notable namesakes range from Oliver Wendell Holmes to Oliver Hardy to Oliver Stone. In fiction, there is Oliver Twist, and Oliver is also a Harry Potter name.
 Oliver works particularly well with single-syllable surnames, as in Oliver Stone, North and Puck (son of Wolfgang). Other celebrities who have chosen Oliver include Bridget Fonda, Fred Savage, Stephen Stills, and Taylor Hawkes. 
 International forms include the French Olivier, the Spanish Olivero, and the Italian Oliviero.
 Parents considering Oliver for their sons might consider that with Olivia at the top of the charts for girls, there will be an awful lot of children with names starting with Oliv-.

This international variation deserves its own listing for a winning combination of distinctiveness and simplicity.

Sofia is a variation of the Greek name Sophia, which was derived directly from sophia, the Greek word for wisdom. It was the name of a Roman saint—the mother of Faith, Hope, and Charity—and queens of Russia and Spain.
 
Sofia is the elegant choice of several celebrities. Lisa Remini, Felicity Huffman and William H. Macy all named their daughters Sofia.
 
The streamlined Sofia spelling is widely used throughout Europe, in Italy, Spain, Scandinavia and Eastern Europe. The Disney Junior show Sofia The First gave Sofia an elegant, royal feel. 
 Variants and diminutives of the name include Sophie, Sofie, Sonia, Zosia and Vivi.
