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

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.

Esther was derived from the Old Persian word stāra, meaning "star." In the Old Testament, Esther, originally named Hadassah, was the captured Jewish wife of the King of Persia who risked her life to save her exiled people from annihilation. This story is celebrated by Jews on the holiday of Purim, so that it has traditionally been given to girls around that time.

Nicholas is derived from the Greek Nikolaos, a name that evolved from the components nikē, meaning "victory", and laos, "people." It shares origins with Nike, the name of the Greek goddess of victory. Nicholas is also a New Testament name that is well-used in literature, such as in Dickens's Nicholas Nickleby.

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.

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.

Cornelius, the New Testament name of a third century Pope and saint, is one of those venerable Latin names on the edge of consideration, despite the corny nickname alert.

Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name. Adam is not as popular as it once was and feels ready for a respite, replaced by newer A names like Aidan/Aiden, Avery and Axel. Its most prominent current bearers include Adams Sandler, Levine, Brody and Driver -- who plays a character named Adam on Girls.

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 baby boy names, it's still widely used.

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.

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.

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.

Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden.

A strong, grounded choice that still has plenty of energy and charm, Leona is the feminine form of Leon, itself derived from the Greek word for "lion". Associated with courage, leadership, and royalty — and the star sign of July and August — Leona is popular in Croatia and Sweden, but familiar across the US, the UK, and continental Europe.

Biblical Jacob ceded his Number 1 spot to biblical Noah, in 2013, after holding first place on the list of baby boy names from 1999 to 2012, given a huge boost by the Twilight phenomenon.

Strong but sweet, Leah is a classic name that doesn't feel dull or dusty. It's got plenty of dignity, grace, and pluck, making it a solid choice in the 21st century.

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.

Amos is a robust biblical name that's being discovered by a new generation of parents in a major way. Similar to other popular choices like Amias, Asa, Moses, and Thomas, it has a contemporary air with plenty of history.

Many vowel names stylish a century ago are coming back, and Ida seems like a possible, logical successor to Ada and Ava.

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.
