Abigail has been in for so long -- the name has ranked in the US Top 100 since the late 1980s -- it's amazing that it isn't more out by now. But Abigail's biblical and historic roots make it a fashionable classic rather than a passing fad.

Although Susan had her heyday from the thirties to the sixties, and is now common among moms and new grandmas, and though most modern parents would prefer Susanna/Susannah, we have spotted some flickers of interest in a revival. It still retains a certain black-eyed-Susan freshness.

To some, Nancy is a sweet, sparkly, vintage choice with plenty of energy and style. For it strays too much into '"old-lady" territory to be cool again yet. It's out of fashion in France, New Zealand, and Canada; it lingers towards to bottom of the US charts. In the UK however, Nancy has been a Top 100 name for nearly a decade where it fits right in with Evie, Mabel, and Pippa.

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.

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.

Catherine is one of the oldest and most consistently well-used girls’ names, with endless variations and nicknames. The Catherine form feels more gently old-fashioned and feminine than the more popular K versions. Most stylish nickname for Catherine right now: Kate...or Cate, a la Blanchett.

Natalie — a Franco-Russian name — became Americanized years ago and is one of those surprising names that's always ranked among the girls' Top 1000 names in the US.

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.

Nicole was derived from Nicholas, the English variation of the Greek Nikolaos, composed of the compounds nike, meaning "victory," and laos, "people." The variation Nicole arose in the Middle Ages in France to honor St. Nicholas. Names related to Nicole include Colette, Nicolette, Nika, Nicola, and Nicolina.

Joan was the perfect name choice for one of the leading characters on Mad Men, being a quintessential girls' name of the period. A Top 10 name in the 30s, a Top 50 name from the 40s through the early 60s, it was the fifth most popular name in the country for three years running and ranks as one of the most common names for girls in the 20th century. But alas, Joan hasn't even appeared in the Top 1000 for a dozen years, and these days it's primarily associated with Joans of the generation of Joan Crawford, Joan Collins and Joan Rivers--just a few of the noted Joans whose ranks also include the singers Joan Sutherland, Joan Baez, Joan Armatrading and Joan Jett. But it's possible that modern parents who are reviving Jane might move on to Joan, inspired by Joan Hollaway Harris.

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.

Since we wrote a book called Beyond Jennifer & Jason, Madison & Montana, encouraging parents to move beyond overused names, it's no secret what we think of this trendy surname name, inspired by a mermaid named Madison in the 1980s movie Splash.

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.

Kayla is a modern invented name that emerged in the late 1950s. It may have been inspired by the similar sounding Michaela, though it could equally have come about as a combination of the then popular name popular name Kay and the familiar -la suffix.

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.

The origins of Samantha are not entirely clear, although it is commonly thought to be a feminization of Samuel with the suffix derived from the Greek anthos, meaning "flower." Samantha has been in English-speaking use since the eighteenth century, particularly in the American South, and drew attention via Grace Kelly's Tracy Samantha Lord character in High Society, featuring the song "I love you, Samantha."

Jennifer is the Cornish variation of Guinevere, which ultimately derived from the Welsh name Gwenhwyfar. It has been in use in the English-speaking world since the 18th century but came to prominence in the 20th. Playwright George Bernard Shaw chose Jennifer for the name of his leading lady in his play The Doctor’s Dilemma, which drew more attention to the name.

Sleek and serious, yet bright and energetic at the same time, Cynthia appears in classic mythology as an epithet for Artemis or Diana. While it is now a more neglected choice, it was once hugely popular in the middle of the 20th-century, peaking at #7 in the US, and in the Top 20 by diminutive Cindy.

Originally a feminine of John, Jean was popular in Scotland long before it found favor elsewhere, and had its most shining moment here in the era of Jean Harlow (born Harlean), ultimate symbol of silver screen glamour. Now, though there are many grandmas and even moms with the name, it doesn't seem all that baby-friendly. Though that could change, and Jean could join Jane.

Barbara is back and among the fastest-rising names of recent years! Credit goes to 2023's breakout movie Barbie, which gave a new stylish feel to the classic Barbara and set it up to rank alongside clunky, retro choices like Deborah, Marjorie, Marilyn, and Dorothy.
