Alexandra fell out of the Top 100 for the first time since 1983 in 2015 but is still a popular choice. Strong, tasteful, and elegant, Alexandra remains a chic modern classic with a solid historic pedigree.
 
Alexandra is the feminine form of Alexander, which ultimately derived from the Greek components alexein, meaning "to defend," and anēr, "man." In Greek mythology, Alexandra was an epithet of the goddess Hera.
 
Alexandra was made fashionable in the English-speaking world by the Danish princess who married England's King Edward VII in 1863, and there have been other royal bearers in both Britain and Russia. Alexandra is the present queen's first middle name. Widely used in Russia, Alexandras can be found in the works of Dostoevsky and Chekhov.
 
International variations include Alessandra and Alejandra. Alexandra offers an array of softer nicknames, from the gender-neutral Alex to the bouncy Lexi to the more dramatic Xandra.

As a highly popular <a href="https://nameberry.com/girls-names">girls’ name</a> in all Spanish-speaking countries, this saintly Latin variation of Mary retains a timeless beauty. Through the centuries, Maria remains one of the most widely-used <a href="https://nameberry.com/search/girls-names/m">girl names starting with M</a>.
 This widespread name understandably has produced notable namesakes in almost every field – opera's Maria Callas (born Sophia Cecelia), tennis's Sharapova, education's Montessori, ad infinitum. And she's been celebrated in song as well, from Ave Maria to the eponymous song in West Side Story to "How Do You Solve a Problem Like Maria?" in The Sound of Music. 
While the usual English pronunciation these days is the same as it is in non-English-speaking countries – mah-REE-ah – the British used to pronounce it mah-RYE-ah, like Mariah Carey.

 Maria ultimately dervies from the Hebrew name Maryam/Mariam. 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).

Maria

This pretty sea-born name was used to dramatic effect by Shakespeare in his play Pericles for the virtuous princess who says she is "Call'd Marina, for I was born at sea." Marina was an epithet of Venus, and there was more than one saint of that name. It was used in Britain from as early as the fourteenth century.
 Although it reached as high as Number 219 in 1994, Marina never had the trendy feel of cousins Melissa and Marissa. It's now very popular in Spain.
 A prominent current bearer is Marina Abramovic, widely publicized New York-based Serbian performance artist. And actor Matt LeBlanc chose the name for his daughter, Marina Pearl.

Marina

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 <a href="https://nameberry.com/boys-names">baby boy names</a>, it's still widely used. 
 
How has Michael racked up this phenomenal record? Credit its use by parents of diverse ethnic and religious groups, and Michael's all-around likability, strength, and sincerity. 
 
Michael was derived from the name Mikha’el, which comes from the rhetorical question mī kā’ēl, meaning "who is like God?" in Hebrew. In the Bible, Michael is the archangel who led the other angels to victory in a war against Satan, one of only two archangels (the other is Gabriel) recognized by Jews, Christians and Muslims alike. 
 
Today, Michael may feel more like a dad name than a baby name. Substitutes you might consider include Micah, Malachi, Gabriel and Raphael.

Michael

Nikolaos

It has historically ranked among the most popular names in countries including Ukraine, Latvia, Spain, France, Serbia, Greece, the US, and many more.

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty. 
 
Derived from sophia, the Greek word for wisdom, the name was first famous via St. Sophia, venerated in the Greek Orthodox church—St. Sophia was the mother of three daughters named Faith, Hope and Love. It was first used in England in the seventeenth century and was the name of George I's both mother and wife.
 
Like its sister baby girl names Isabella and Olivia, Sophia has gained widespread favor by appealing to a broad range of parents: Intellectuals who like it for its meaning and those attracted to its femininity, parents who want a classic name and those looking for a name with Latin roots—the Sofia spelling is also popular. Sophie is the French version of the name, more popular than Sophia in some parts of the world. Legend Sophia Loren was originally Sofia.
 
Sophia has been an author favorite from the days of early novelists like Henry Fielding (Tom Jones) and Jane Austen (Persuasion) to the TV scriptwriters of today (The Walking Dead, Orange is the New Black).
 
Sophia's only downside is its huge popularity; it's actually even more popular than it appears, because alternate spelling Sofia falls in the Top 20 on the US popularity chart. Alternative baby names you might want to consider: Sophie, Seraphina, Susannah, Zofia.

Sophia

Sophie is the French form of the Greek Sophia, for which it is also commonly used as a nickname. Given Sophia's long standing among the Top 10 girl names in the US, Sophie may feel more popular than it actually is.
 
Sophies are scattered throughout European royal history, including Sophie of Thuringia, Duchess of Brabant, Princess Sophie of Sweden, and in modern times, Sophie, Duchess of Wessex, the wife of Britain's Prince Edward. German-born Catherine the Great was born Sophie of Anhalt-Zerbst, but changed her name to Catherine upon her conversion to Russian Orthodoxy.
 
Sophie is Sophia's cuter, more irreverent near-identical twin. Which do you like better? And do you see them as virtually the same name or very different? While you definitely couldn't name sisters Sophie and Sophia, you may have both on your short list and consider them distinctly separate choices. Sophie is lively and down-to-earth, while Sophia is more sophisticated and buttoned-up. 
 
Sophie was the choice of both Eric Clapton and Luke Perry, as well as of Bette Midler for her now-grown daughter.
 Sophie Zawistowska is the Polish heroine of the iconic William Styron novel Sophie's Choice, played in the 1982 film by Meryl Streep—who would play the mother of a Sophie decades later in Mamma Mia!.

Sophie

Theodora is one of the most revival-worthy of the charmingly old-fashioned Victorian valentine names, softly evocative but still substantial, as is the reversed-syllable Dorothea. 
 
The name Theodora was borne by several saints and by the beautiful ninth wife of the Emperor Justinian, who became the power behind his throne. A later royal was Princess Theodora of Greece and Denmark, the older sister of the late Prince Philip, Duke of Edinburgh. 

 Keith Richards named his daughter Theodora (with whom he recently collaborated on a best-selling children's book) in 1985; Robbie Williams did the same just last year. In TV's Grey's Anatomy Dr. Theodora "Teddy" Altman was a surgeon.

 Theodora offers a menu of neat nicknames, from the classic Teddy to trendy Thea to the vintage Dora. Theodora also has some cool international variations as well: Theodosia, Feodora and Teodora. It reentered the US Top 1000 in 2019 for the first time in over 60 years and seems destined to follow brother name Theodore toward the top of the list.
