Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.
 Alexander is derived from the Greek name Aléxandros, composed of the elements aléxein, meaning "to defend," and aner, meaning "man." 
 
According to Greek legend, the first Alexander was Paris, who was given the nickname Alexander by the shepherds whose flocks he defended against robbers. He was followed by Alexander the Great, aka Alexander III, who conquered much of Asia.
 
A royal name in Scotland, Alexander is still highly popular there. In Gaelic, the name became Alasdair; in Spain, Alejandro; and in Italy, Alessandro.
 
The noble Alexander has led to the popularity of many spinoffs, such as Alex, Zander, Xan and Zan, along with female versions such as Alexandra, Alexis, and the unfortunate Alexa.
 Among the many notable Alexanders in history, standouts are Hamilton, Graham Bell, Fleming, Pope and Haig.
 Naomi Watts and Liev Schreiber's Alexander is known as Sasha.

Dalton is a name with multi-faceted appeal. Many are attracted to the name's resemblance to other two-syllable n-ending favorites: Colton, Holden, and cousins. Others see it as a trendy Western name, recalling the legendary Dalton Brothers gang. It also has something of an upscale, preppy feel connected to the exclusive New York private school. 
 The most well known bearer of the name is blacklisted screenwriter Dalton Trumbo, but there have been a number of high-profile fictional Daltons as well. Dalton Rumba was an adult character on Glee, Clive Owen played a Dalton in Inside Man, there was a scholarly Dalton on Buffy the Vampire Slayer, and Patrick Swayze opened the film Roadhouse by stating "My name is Dalton Russell."

Unlike most creative spellings, this one isn't overly trendy or overdone—in fact, it's quite delicate and pretty. However, it is clearly suffering from the plethora of similar names that are flowing around right now (Emelie, Emilia, Emily, Emilee, Amelie, Amelia) and has fallen more than 300 spots since 2013. It might be time for Emilie and her sisters to be left alone for a while.

Serene Irene, the name of the Greek goddess of peace and one of the most familiar <a href-="https://nameberry.com/list/624/gorgeous-greek-goddess-names-for-babies">Greek goddess names</a>, was hugely popular in ancient Rome and again in the United States a hundred years ago.
 One of the most <a href="https://nameberry.com/popular-names">popular names</a> of the Roman Empire and the name of several early saints, this originally Greek name (then spelled Eirene) represented a daughter of Zeus who was the goddess of peace. Often pronounced with three syllables, it spread throughout Europe in a range of variations and is a royal name in Greece, Denmark, and the Netherlands. 
 Much of Irene's popularity in England stemmed from the character Irene Forsyte in Galsworthy's The Forsyte Saga (pronounced eye-reen-ee). Americans identified it with the sparkling Irene Dunne of Hollywood's Golden Age. Irene was a Top 20 name from 1915 to 1925, remaining in the Top 100 until 1945. It still highly popular in Spain.
 Some other references include the eponymous early smash hit Broadway musical, famed ballroom dancer Irene Castle (portrayed on film by Ginger Rogers), the Hollywood costume designer known simply as Irene, the Uma Thurman character in Gattaca, Irene Denholm the Harry Potter student at Hogwarts School, and the lullaby-ready song Goodnight, Irene.

For centuries this name was associated primarily with the towering figure of Italian Renaissance painter-scientist-inventor Leonardo da Vinci, and was scarcely used outside the Latin culture. 

But then along came Leonardo DiCaprio, who was supposedly given the name because his pregnant mother felt her first kick while looking at a da Vinci painting in the Ufizzi Gallery in Florence, and who would make the name young and handsome and multi-cultural. 
 Leonardo is a popular choice among other attractive Italian and <a href="https://nameberry.com/baby-names/806/spanish-names-for-boys">Spanish names for boys</a>, and its cousin Leo is popular as well.

Noam is an underused modern Hebrew name with any number of attractive attributes attached to its meaning; it doesn't have the biblical weight of Noah, but could make a more distinctive alternative to that popular choice. Noam is a Top 10 boys' name in Israel. Noam is also a place-name in south Israel, where it is sometime used for girls. Its most prominent bearer is the distinguished linguist and social activist Noam Chomsky (born Avram Noam).

A solid classic with plenty of history, Thomas strikes the balance between strength and gentleness. A favorite in the UK, a staple in France, and Australia, and never absent from the US Top 100, Thomas feels like a safe bet and a name that fits into any era. 
The Greek form of the Aramaic name Ta’oma, Thomas means “twin.” It came about in the Bible because there were too many apostles called Judas, and so, Thomas became the “twin”, to reflect his close brotherhood with Jesus. 
Known as “Doubting Thomas” due to his initial skepticism of Jesus’s resurrection, he went on to become a martyr, and there was no need to doubt Thomas’s potential as a given name. 
Brought into common usage by the Normans, it was then always among the 5 most common English names for boys at any point between the 13th and 19th century. 
While it has fallen down the US charts in recent years, it remains a familiar and trusted choice. Given to over 6000 boys every year, it has made a steady climb back into the Top 50. 
Across the pond in the UK, both Thomas and Tommy make the Top 30, while Tom, Tommy-Lee and Tommie have made their mark in the Top 1000. 
As a well-established classic, Thomas naturally comes with plenty of noteworthy namesakes. “Thomas the Tank Engine” might appeal to you kids, but there’s also the theologian, Sir Thomas Aquinas, the cardinal Thomas Wolsey, the Founding Father, Thomas Jefferson. the philosopher, Thomas Hobbes, and the writer, Thomas Hardy. 
More recent namesakes for those who aren’t into history include actors Tom Hardy, Tom Cruise, and Tom Hiddleston, singers Tom Parker and Tom Fletcher, Olympic diver Tom Daley, and Thomas Sanders, of YouTube fame. 
A timeless all-rounder, Thomas comes with the intuitive nicknames, Tommy and Tom, which feel sweet for a child but not too cutesy for a grown-up. For more unexpected options, you could try the nature-inspired Moss or Scottish Tam. 
Unlikely to go out of style anytime soon, Thomas is a refined but approachable choice. If the popularity does give you pause, however, you could try the surname-inspired Thompson, or an <a href=“https://nameberry.com/list/492/100-classic-boys-names--below-the-top-1000/all”> underused classic</a> like Marius, Rufus, or Phinneas. 
Alternatively, there is a wealth of interesting variants to ponder, from Italian Tommaso and Scottish Tavish to Croatian Tomo– and for girls, there’s Thomasina, Tomine and Tamsin.
