Names that Peaked in 1900

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular baby name beginning with W of all time.

Iconoclasts though we may be, we like Fred, we like Frank, and we like George, which was among the Top 10 from 1830 to 1950, when the number of little Georges started to decline. Solid, strong, royal and saintly, yet friendly and unpretentious, we think that George is in prime position for a comeback, especially since it was chosen by Britain's royal couple.

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.

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).

Lillian has ranked among the US Top 50 for the past 20 years, making it Lily's less popular but more grownup cousin.

Pearl, like Ruby, has begun to be polished up for a new generation of fashionable children after a century of jewelry box storage. The birthstone for the month of June, Pearl could also make a fresher middle name alternative to the overused Rose. Cool couple Maya Rudolph and Paul Thomas Anderson named their daughter Pearl Minnie, followed by Jack Osbourne, and several celebs have put it in the middle spot, as in Busy Philipps's Cricket Pearl, Jake Owen's Olive Pearl and Caleb Followill's Dixie Pearl .

Helen is a name that has connoted beauty since ancient times – Helen of Troy was the the mythological "face that launched a thousand ships," over whom the ten-year Trojan War was fought.

Mack, when "formalized" with the final k, makes an engagingly amiable choice, a far more uncommon alternative to the ubiquitous Max and Jack, with a nice, every-guy feel. Mack entered the popularity list in 2009 for the first time since 1989 and continues to climb. However, it's still far from its peak — it was a Top 100 name in 1900.

A name that has a bit of a shouldn't-I-be-a-middle-name sound, though still in use as a first for both genders. Lee might be a good choice if you want something that sounds at once traditional yet modern, unisex but not newly-minted.

An appealing Irish placename with a unisex feel, Ennis would be a fresh alternative to Dennis and Ellis. It's little-used for boys and even rarer for girls, but since Kirsten Dunst and Jesse Plemons used it for their son, it could be one to watch.

The -ie version is usually for girls, with the simple e ending—pronounced the same as Jessie—for boys, though the spellings sometimes cross gender lines.

Though Collins makes the Top 1000 for girls, it sounds strong and handsome for boys too, kind of like the newly-stylish Brooks. The final s updates it from the 80s-ish Colin or the Twilightish Cullen. Might make an innovative honorific for a grandpa Nick.

Mauve-tinted nickname with vintage charm that could just follow in the footsteps of ABBIE. More prominent now as the nickname for the Texas A&M sports teams.

Attractive form still très Parisienne.

Ancient saint's name used for cowardly cartoon lion.

If it's possible for a name to be too musical, this one is.

Waverly, with its literary resonance and lilting three-syllable sound, could well become the next generation's successor to Kimberly. Although, like Kimberly, it's overwhelmingly catching on for girls. Its cool, bohemian surname feel places it among the new stylish English names for girls, successors to Ashley and Whitney.

Ossie is best-known as the name of actor Ossie Davis, whose full name did not start with Os: It was Raiford. But Ossie makes a cute contemporary short form for any name beginning with Os.
