Why not make it a dozen? Top 12 favorites

Isa is a name unto itself as both a Persian name meaning "strong-willed" and as Germanic one derived from the element is meaning "ice". It can also be a short form of Isabel, Isabella, Isadora, Louisa, and similar. Currently popular in Brazil and The Netherlands, it has seen some increased use in the US in recent years, perhaps owing to the popularity of other short names like Ava, Mia, and Isla.

Why is Isabella megapopular while Isadora goes virtually ignored? Too close a tie with tragic modern dancer Isadora Duncan (born Angela Isadora), who was done in by her long flowing scarf, perhaps, or with fusty male version Isidore. But we think Isadora is well worth reevaluating as an Isabella alternative. Quirky couple singer Bjork and artist Matthew Barney did just that and named their daughter Isadora. Isidora would be an alternative, just as proper but not quite as charming spelling--the one used as the spelling of a fourth century saint's name.

Isaiah, like brethren Isaac and Elijah, is a once neglected biblical name now firmly back in favor, already surpassing such long-popular Old Testament stalwarts as Aaron and Adam. Isaiah has ranked on the US Top 1000 list for boys every year but two, 1969 and 1970.

The rise of the the various Isabel names may give a boost to this variation, which has a sunny, springtime feel.

Jedidiah, an Old Testament name with a touch of Gunsmoke-era western panache, is right in line to be revived along with the other biblical -iah names.

Judah is the strong, resonant Old Testament name of the son of Jacob who was the ancestor of one of the tribes of Israel, and from whom the word Jew is derived. Some of the names' popularity might be attributable to the similarly named Jude Law.

Jude is a modern star, maintaining a steady level of popularity -- but not TOO much popularity -- for more than a decade now. Thank Jude Law and the great Lennon-McCartney song "Hey Jude", double-handedly responsible for propelling Jude up the charts.

Popular in the first half of the 20th century, Leland briefly fell out of favor in the late 90s. After a short break from the US charts, it returned in the mid-2000s, with actor Brendan Fraser choosing it for his youngest son, possibly making it feel cool again. Given to around 500 boys each year, Leland is in the Top 600.

Its mellifluous sound makes Leonora--which has a rich history and a tie to the popular Leo names-- a keen possibility for revival. Though it's been hiding below the Top 1000 since the 1940s, Leonora is being rediscovered by stylish parents in the US and Europe.

Liam is the top boys' name in the US, holding the Number 1 spot for the past seven years and also ranking as one of the most popular boys' names around the western world.

Lincoln cracked the Top 50 for boys' names for the first time in 2016, more than 150 years after the death of its most famous bearer. This is especially remarkable because, as crazy as it seems now, Lincoln was deeply out of fashion as recently as the late 90s, consistently hovering near the bottom of the Top 1000.

Lucan is a rarely heard Irish name, a Luke form with the trendy an ending.

Luka is one of the coolest names in recent years, following suit of its cousin Luca which is now a Top 50 name. Luka is on its way up the charts and may crack the Top 100 in the very near future. Luka has a lot going for it — it is following the tails of Lucas and Luke which have been enjoying significant popularity for years. It also boasts the very current "-ah" ending sound that feels fresher than ever for boy names, from Noah to Ezra to Judah. The "k" in the middle gives an extra edge as well.

Mae, a sweet and springlike old-fashioned name, hadn't been on the national charts in forty years, but finally made it back in 2010. Mae is derived from May, the month name that was chosen for its connection to Maia, the Roman goddess of growth and motherhood.

Nico is one of the great nickname names, full of charm, energy and effortless cool -- a neo Nick.

Noah is nearly a patriarch of popular baby names at this point, going from Old Testament graybeard to Top 10 name in 2009, hitting Number 1 in 2013, and now settled into second place in the US for the past seven years.

Nora is a lovely, refined name that conjures up images of Belle Epoch ladies in fur-trimmed coats skating in Central Park. Long seen as a quintessentially Irish name though its roots are not in Ireland, Nora is a quietly stylish favorite that's tiptoed to the top of the popularity ladder.

The skyrocketing success of singer Norah Jones brought this spelling of the name onto the pop charts in 2003. As well as being a spelling variant of Nora in English, it's also an alternative transcription of the Arabic name Nura, from Nur/Noor "light".

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.
