Nicholas is derived from the Greek Nikolaos, a name that evolved from the components nikē, meaning "victory", and laos, "people."

Energetic, sunny, and slightly romantic, Rafael is a popular choice in Germany, Spain, Portugal, and Croatia. Used internationally, Rafael is a Spanish variation of Raphael, that lends itself easily to the nicknames Rafi, Rafa and Rafe.

Eric is derived from the Old Norse name Eiríkr, from the components ei, meaning "ever," and ríkr, "rule." It was adopted by English speakers in the mid-nineteenth century, who were already familiar with the exploits of the tenth century Viking navigator and discoverer of Greenland, Eric the Red. Erik is an alternate spelling and the preferred form of the name across much of Europe.

Frederick, and friendlier nickname Fred, seemed almost to have disappeared, leaving just the memory of Freds past such as Astaire, Mr. Rogers and Flintstone. But today's parents are beginning to recognize it as a strong classic and one of the top royal baby boy names.

Sweet and spirited, kindly and handsome, posh and approachable, Toby is a versatile nickname, popular in the UK as a stand-alone choice, but familiar in the Netherlands and New Zealand too. In the US, it had its heyday in the 70s but has since been outranked by long form Tobias.

Raphael is a romantic archangel name that sounds both artistic and powerful. Raphael is also a great cross-cultural choice, with significance for people with both Latinate and Jewish roots, plus plenty of grounding in the English-speaking world.

The name Christian has fallen a bit from its 90's and 00's heights, but it's still quite popular. Once considered overly pious, Christian is now seen as making a bold statement of faith by some, while also having secular appeal for others.

Tiago, also spelled Thiago, is a popular Portuguese boys' name. Derived from the more formal Santiago, these days it is often used on its own.

Greyson and Grayson, nephews of Jason, are both on the fast track. Both variations have made their way all the way up to the Top 100 since 2016. Gray/Grey makes a nice nickname.

Some parents are considering Grayson -- or Gracen or Gracyn -- for girls as an androgynous spin on Grace.

Like many short forms now popular as full names in the Netherlands, Coen—also spelled Koen—originated as the diminutive of the more old-fashioned Coenraad, the Dutch Conrad. In this case, it would be pronounced as KOON, with a short oo sound.
Alternatively, it may be used in the US as a variation of Cohen, which stems from the Jewish surname designating a priest, and thus pronounced as CO-uhn. Additionally, it may also relate to the Irish surname McCown ("of Connacht") or to the Australian place name, Coen, meaning "thunder" from its Indigenous roots.

Emiliano is an appealing Latinate version of Emil, with the same gentle sounds but additional flair. Popular in Chile and Mexico, where it ranks in the Top 20, Emiliano is also a rising name in the US.

Today Nicolas is popular among Spanish and Portuguese-speaking parents, ranking in the Top 30 in Spain, Brazil, and Chile.
