Sarah was derived from the Hebrew word sarah, meaning "princess." Sarah is an Old Testament name — she was the wife of Abraham and mother of Isaac. According to the Book of Genesis, Sarah was originally called Sarai, but had her name changed by God to the more auspicious Sarah when she was 90 years old.

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.

Thanks to its dashing Anglo-Irish image — due partly to Colins Firth and Farrell — and its C-initialed two-syllable sound, Colin and its cousin Collin have enjoyed a long run of popularity, reaching as high as Number 84 in 2004.

Ralph has two diametrically different images: there's the suave Ralph Fiennes-type Brit (often pronounced Rafe), and then there's the Jackie Gleason blue-collar, bowling blowhard Ralph Kramden bus driver. It's all in the eye of the beholder, though its hip factor did rise when it was chosen for his son by cool U.K. actor Matthew Macfadyen.

With its rugged, country charm and confident sounds, Waylon is among the wave of Old Western names that parents are choosing.

We've seen Ray regain his cool, but could this country/cowboy name epitomized by Roy Rogers (born Leonard Slye), Acuff, and Clark, do the same?

Ruth, with its air of calm and compassion, was the third most popular name in the 1890s, remaining in the Top 10 through the 1920s. It's still in use today as some parents tiring of Rachel and Rebecca are giving Ruth a second thought. Some see such Old Testament girls’ names as Ruth and Esther rising on the heels of boy equivalents Abel and Moses.

This no-nonsense German variation of Charles is strong and sturdy. A top choice throughout the 20th century, Carl is now verging on falling off the charts.

Greta is an Old World name long tied to the iconic Garbo, but now synonymous with environmental activism.

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.

Alexandra fell out of the Top 100 for the first time since 1983 in 2015 but is still a popular choice. Strong, tasteful, and elegant, Alexandra remains a chic modern classic with a solid historic pedigree.

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).

Jacqueline originated as a feminine form of Jacques, the French variation of James, and therefore Jacob. Jacob was ultimately derived from the Hebrew name Ya’aqov, and gets its meaning, "supplanter" from the story of Jacob supplanting his brother Esau as the first-born son in the Bible. Jacqueline was first used in France in the Middle Ages.

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.

Constance is one of the more subtle of the virtue baby names, but still has quite a prim and proper image. One impediment to its revival has been the decidedly dated nickname Connie, though modern parents might well opt for using the strong and dignified name in full.

Patrician to the core, Hugh was firmly in the Top 100 until 1903. It's never achieved those heights again, though it has always managed to remain in the Top 1000, scraping bottom at literally Number 1000 in 2006 before reversing course and heading back upwards.

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.

Joseph is one of the most classic names in American nomenclature, popular with parents from many ethnic backgrounds and having dual-religious appeal.

When Jennifer finally gave up her Number 1 place on the girls' popularity list, her crown was passed to Jessica, who reigned for not one but two decades. Jessica was the Number 1 name in both the mid-1980s and 1990s, never sounding quite as trendy as its predecessor, maybe because of its classic Shakespearean pedigree.

Maude, also spelled Maud, is a lacy, mauve-tinted name that was wildly popular a hundred years ago, but has been rarely heard in the past fifty. Some stylish parents are starting to choose it again, especially as a middle.
