Names from 16 and Pregnant Season 2

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.

Aidan was originally a pet form of the Irish name Aodh (pronounced 'ee'), the name of the old Celtic god of the sun and fire. The name was borne by numerous early Irish saints, one of whom was noted for his kindness and generosity.

During its Top 10 heyday in the late 90s and early oughts, Andrew was one of the "cooler" classic boy names, an update on the old guard Roberts and Richards.

Aubree and its big sister name Aubrey are both very widely used names, and if taken together would be among the most popular girl names. The Aubree spelling came into the limelight on the show Teen Mom 2.

Extreme makeover: Brooklyn has gone from jokey Borough Boy name in the 1990s to a leading girls' name starting with B. The status of New York's Brooklyn as hipster heaven is ironic as few bona fide Brooklyn hipsters would choose this name.

Chelsea is still being used, with about 400 baby girls named Chelsea in the US last year. But it was much more popular a few decades ago, peaking at Number 15 in 1992.

Former teen idol name, now middle-aged. This name has been on a steady decline since the early-1990s.

Eric is derived from the Old Norse name Eiríkr, from the components ei, meaning "ever," and ríkr, "rule." It was adopted by English speakers in the mid-nineteenth century, who were already familiar with the exploits of the tenth century Viking navigator and discoverer of Greenland, Eric the Red. Erik is an alternate spelling and the preferred form of the name across much of Europe.

Isaac has shaved off his biblical beard and leaped into the upper echelon of popular boys' names, outrunning cousin Isaiah. A favorite of the Puritans, Isaac has never dipped below Number 400 on the US list of top boy names.

Jace may sound like only half a name -- it's usually pronounced like the first half of Jason though some may consider it a spelling-out of the initials J. C. -- but it's a popular choice for baby boys. Jace has been heard on such TV shows as Teen Mom 2 and Duck Dynasty.

Combo name wedding two long-popular syllables.

Jonathan was derived from the Hebrew name Yehonatan, eventually contracted to the modern Yonatan, meaning "gift of Jehovah." It comes from the elements yeho, in reference to God, and natan, meaning "to give." In the Old Testament, Jonathan was the valiant eldest son of King Saul, and it was his friendship with brother-in-law David that gave rise to the expression "Jonathan and David" to describe devoted, steadfast friends.

Jordynn is one of the many spelling variations of Jordan—and it does not improve on the original. This iteration has appeared in the US Top 1000 since 2010, though it's currently at its lowest point since then.
