Harrison, a name made viable by Harrison Ford, is increasingly popular with parents who want an H name that's more formal than Harry or Hank but doesn't veer into the stiff Huntington-Harrington territory.

Charlie derives, of course, from the classic name Charles which, in turn, comes from a German word meaning "free man." Charles became very popular in France during the Middle Ages due to the fame of Charles the Great, also known as Charlemagne. Charley is an alternate spelling.

Peter is derived from the Greek Petros, meaning "rock" or "stone." One of the most important figures in the Christian hagiography is Saint Peter, keeper of the Gates of Heaven. Born Simon bar Jonah, he was given the nickname Peter by Jesus, to signify that he would be the rock on which Christ would build Christianity. Centuries later, there was Peter the Great, the czar who developed Russia as a major European power.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

Max was derived from Maximilian, a Latin name that originated from the Roman family name Maximus. The character name Max in the children's classic Where the Wild Things Are had an impact on baby namers. Max is a widely used name internationally.

Austin is one of the most attractive city names for babies, with an appealing southwestern feel and place-name panache.

Isaac has shaved off his biblical beard and leaped into the upper echelon of popular boys' names, outrunning cousin Isaiah. A favorite of the Puritans, Isaac has never dipped below Number 400 on the US list of top boy names.

Samuel has been so popular for so long that it's hard to believe it's still climbing, at its highest point since the 1890s.

Daniel is one of only a handful of male names that sounds both classic and modern, strong yet approachable, and popular but not cliched. It also has a solid Old Testament pedigree. The only real downside: There are about 10,000 Daniels named each year, making it a less than distinctive choice.

Robert was the Number 1 boys' name in the US in both 1925 and 1950, and in fact was in the Top 25 for more than a century, giving it true classic status. Strong if not quite stylish, Robert remains in the Top 100 for baby boys as a family favorite.

Kate and William shocked the world when they announced that they'd named their third child Louis, or Prince Louis Arthur Charles, to be more precise. But we've been predicting a comeback for this classic name for a long time.

Biblical Jacob ceded his Number 1 spot to biblical Noah, in 2013, after holding first place on the list of baby boy names from 1999 to 2012, given a huge boost by the Twilight phenomenon.

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 baby boy names, it's still widely used.

One of many R- boys’ names that started as a nickname for a redhead, Russell had a measure of popularity from the early twentieth century through the 1950s. But it's now lost much of its color -- except for a few dynamic bearers, actors Russell Crowe and Russell Brand and sports stars Russell Westbrook and Russell Wilson.

Victor is one of the earliest Christian names, borne (as Vittorio) by several saints and popes, symbolizing Christ's victory over death. It has been quietly in the Top 200 since 1880, but just recently has taken on a cool edge by fashionable parents in London and seems ripe for a similar reevaluation here too.

Solomon, a name that evokes wisdom and peace, is an Old Testament name that, along with other patriarchal classics, is finally beginning to shed its long white beard and step from the pages of the Old Testament into modern nurseries.

Nicholas is derived from the Greek Nikolaos, a name that evolved from the components nikē, meaning "victory", and laos, "people." It shares origins with Nike, the name of the Greek goddess of victory. Nicholas is also a New Testament name that is well-used in literature, such as in Dickens's Nicholas Nickleby.

Mason is an occupational surname that ranked among the Top 10 name for boys throughout the 2010s, after its choice as one of the first Kardashian baby names. It remained a Top 10 choice in the US until 2020 when it began trending downwards and a recent year saw it rank at #42, the lowest it's placed since 2005.

The Top 10 boys' name Elijah is derived from the Hebrew name Eliyahu, composed of the elements ’el and yah, both of which refer to God. In the Old Testament, Elijah was the prophet who went to heaven in a chariot of fire, a story sure to inspire any young Elijah.

Lawrence has survived from Roman times, when Laurentium was a city noted for its laurel trees (the laurel is a symbol of wisdom and achievement). It was in the Top 50 from the 1890s through the 1950s and the Top 100 for decades longer, always among the most popular boys' names starting with L, but Lawrence is now used less for babies than Landon or Lorenzo.
