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.

Mary is the English form of Maria, which ultimately was derived 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).

Julia was an ancient Roman imperial name given to females in the house of a Julius, as in Caesar. Its origin is shrouded in history, but possible roots include Latin iuvenis, meaning "youthful"; Greek ioulos, meaning "downy-bearded"; or Jovis, a form of Jupiter, which means "sky father".

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.

Sara, the streamlined form of Sarah, makes this ancient name feel more modern, but perhaps a bit lighter weight.

A second-tier classic, the New Testament Timothy moves in and out of fashion more than John and James. But though it peaked in the 1960s, many modern parents still appreciate its familiarity and lively rhythm. And the short form Tim feels eternally boyish.

Simple, classic, strong, and versatile, Jane has shrugged off her plain associations to become a short, punchy name with plenty of literary significance. Calling to mind Jane Austen and Jane Eyre, this charming choice is in the Top 300 in the US and The Netherlands, but a currently underused option elsewhere.

A classic old Norman name popular for a thousand years and favored for kings (Richard Nixon was named for Richard the Lionhearted), as well as the hoi polloi (as in every Tom, Dick and Harry), Richard was the sixth most popular US boys’ name in 1925, and was still Number 8 in 1950, but is now much less popular.

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.

Rachel was derived from the Hebrew word rāchēl, meaning "ewe." In the Old Testament, Rachel was the favorite wife of Jacob, and mother of Joseph and Benjamin. International variations include the Spanish Raquel and Israeli Rahel.

Walter was seen as a noble name in the Sir Walter Raleigh and Sir Walter Scott era, but it then spent decades in baby name limbo. Now quite a few independent-minded parents are looking at it as a renewable, slightly quirky, classic, stronger and more distinctive than James or John, second only to William among the handsome classic boy baby names starting with W.

Malcolm is a warm and welcoming Scottish appellation (originally Mael-Colium) that fits into that golden circle of names that are distinctive but not at all odd. A royal name in Scotland, Malcolm is also a hero name for many via radical civil rights activist Malcolm X.

Martin is one of those names like Arthur and Vincent and George that is in the process of throwing off its balding middle-aged image to start sounding possible again, used in full without the dated Marty nickname.

Laura is a hauntingly evocative perennial, never trendy, never dated, feminine without being fussy, with long-standing literary links. All this makes Laura a more solid choice than any of its more decorative counterparts and one of the most classic girl names starting with L.

Lewis is the best spelling to choose if you want this pronounced with the S. It was a Top 100 name in the US from 1880 to 1930, reaching Number 30 in 1880 and while it has declined in use, it has remained in the Top 1000 since stats began.

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.

A Top 10 name from the 1880s until the 1920s, Frank has been falling for decades but last year reversed course for the first time in a century, edging up the popularity list a few notches. And Frank still has a certain warm, friendly real-guy grandpa flavor that could come back into style, like other such choices as Jake and Jack.

Louise has for several decades now been seen as competent, studious, and efficient—desirable if not dramatic qualities. But now along with a raft of other L names, as well as cousin Eloise, Louise is up for reappreciation—sleek and chic, stylish in Paris, and starting to become so in the US as well. Louisa is perhaps more in tune with the times, but Louise has more edge. Louise has been on the rise lately, and reentered the US Top 1000 for the first time in a quarter century in 2016.

Flora, the name of the Roman goddess of flowers and spring, who enjoyed eternal youth, is one of the gently old-fashioned girls' flower names that's making a big comeback. Short and sweet, it joins Cora, Florence, Iris, and Ivy in the charts.
