Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

Margaret is derived from the French Marguerite, which in turn came from Margarita, the Latin form of the Greek Margarites. Margarites was based on the Old Persian word margārīta, meaning "pearl."

Agnes is the Latin variation of the name Hagne, which itself derived from the Greek word hagnos, meaning "chaste." In medieval times, St. Agnes was a very popular saint, leading to its popularity as a girl's name. Agnes Grey is the title of one of the two novels written by Anne Brontë.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four girl names starting with O on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen.

Though never as popular as the name of her Bewitched mother, Samantha, Tabitha has its own quirky, magical charm. The name of a charitable woman who was restored to life by Saint Peter in the Bible, it was a popular Puritan choice. Sarah Jessica Parker and Matthew Broderick chose it for one of their twin daughters, which gave it a slight boost. Nonetheless, Tabitha remains in decline.

Anna has become the dominant form of the Ann family, offering a touch of the international to English speakers and a bit more style than the oversimplified Ann or Anne.

Hannah is one of the nation's top biblical girls' names — it surpassed Sarah in 1998, and ranks in the Top 100 along with Elizabeth, Abigail, Chloe, and Naomi. Hannah is a name with many sources of appeal: Old Testament roots, soft and gentle sound, and a homey yet aristocratic image.

Adelaide is now heading straight uphill on the coattails of such newly popular sisters as Ava, Ada, and Audrey, and in the company of Adeline and Amelia. It was chosen by actress Katherine Heigl for the name of her second daughter.

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).

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.

Edith was a hugely popular name a hundred years ago that's being revived among stylish parents in Stockholm and London. It's currently beginning to gain traction in the US among those with a taste for old-fashioned names with a soft but strong image.

The name is derived from the term commonly used in the Book of Psalms, which has a many Hebrew scholars in confusion over its meaning. Given its context in the Bible, Selah is likely to mean "to praise" or "pause and reflect upon what has just been said." Lauryn Hill used this name for her daughter. It is the last word in Anita Diamant's novel The Red Tent.

Lucia is a lush, rich Latinate equivalent of Lucy, popular in Spain and throughout Latin America and also a cross-cultural favorite. You might be surprised to know that Lucia has ALWAYS ranked among the Top 1000 girl names in the US, though she's really taken off only since the turn of this century.

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.

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.

Harriet has long been considered a stylish, upscale name in England, but it's still waiting to be revived in the US—though some parents seeking a solid, serious semi-classic are beginning to consider it.

Minnie was wildly popular at the turn of the last century — it was the fifth or sixth most popular name throughout the 1880s — but is completely obscure in the US today. Blame Mickey's girlfriend. Regardless, it's possible that the up and coming trend toward old-fashioned nickname-names — think Maisie, Mamie, Millie — may give Minnie (all on its own, not as a short form of anything) a new moment in the sun.

Katherine is one of the oldest, most diverse, and all-around best names: it's powerful, feminine, royal, saintly, classic, popular, and adaptable. Long one of the top girls' names starting with K, Katherine has now been unseated on the popularity list by upstarts Kennedy and Kinsley, but a dip in popularity only adds to its charm.

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.

Meredith is a soft, gentle-sounding name with subtle Welsh roots. Although originally a boys’ name , Meredith is used mainly for girls now.
