Derived from the Scottish Gaelic bàn, meaning "white, fair". It's also a name in J. R. R. Tolkien's fictional Elvish language, in which it means "beautiful".

Bain

An undiscovered option among occupational names, Banner has never been used for more than 100 baby boys in a single year. But Banner has undeniable charm, much due to its associations with fêtes and phrases like "a banner year".
 
Actor Jesse Eisenberg has a son named Banner, born in 2017.

Banner

Great Irish middle name choice for Shakespeare lovers. 

Bard

If you're going to choose a noble word name, why not aim higher and pick Duke, Prince...or King. The Donald Trumps picked the Barron spelling for their little princeling. 

Baron

In Spanish cultures, and spelled either Bastian or Bastien, this is a fairly common nickname name. The German fantasy children's book The Neverending Story features a young boy character called Bastian Balthlazar Bux, and it has also been seen in several screen versions. 
 Bastian has been enjoying recent popularity in Latin America: it reached Number 11 in Chile--as well as in Germany and Scandinavia, and is just beginning to be appreciated here. Jeremy Sisto used it for his son.
 Alternate spelling Bastien is also a fashionable Euro form with a possible future in America. There is a one-act comic opera by Mozart titled Bastien und Bastienne.

Bastian

As Bas, it's a popular name in The Netherlands, but Baz, as in director Luhrmann, has potential for independent life too.
Curiously, Australian-born Moulin Rouge director Luhrmann was born neither Sebastian nor Basil, but had the name Mark Anthony on his birth certificate; his nickname arose from his supposed resemblance to a British TV fox puppet named Basil Brush.

Bear has suddenly lumbered onto the baby name landscape.  Perhaps inspired by British adventurer Bear Grylls (born Edward Michael), first celebrity chef Jamie Oliver used it as the middle name for his boy Buddy, and more recently Alicia Silverstone called her son Bear Blu., followed by Kate Winslet's Bear Blaize. It's part of a current trend normalizing once aggressive animal names like Wolf and Fox. Bear is now Number 218 on Nameberry and in the Top 900 in England.

Bear

The popular single-named alternative singer (born Bek) has given this cool nature-meets-surname name a new lease of life. Another notable bearer is Beck Weathers, a Texan pathologist who survived the 1996 Mount Everest disaster, which was covered in the book and film Into Thin Air.

 Outdoorsy yet refined, Beck still sits below the radar but could follow brother Beckett up the charts.

Beck

This ancient name is that of the hero of the epic Beowulf, which is thought to be the oldest-ever poem in English lit written in the vernacular. J. R. R. Tolkien used the poem as one of his inspirations for The Lord of the Rings.

Certainly a weighty if historically relevant choice, but usable for a modern baby? Even a few years ago, we might have said no. But Beowulf Sheehan is a noted portrait photographer, Beowulf Borritt a Broadway production designer, and the nicknames Wulf or Wulfie are feeling positively mainstream.

With other ancient names from myth and legend coming to life once again, Beowulf is certainly up for consideration.

Beowulf

One of the new crop of boys' names that manage to be unconventional and macho at the same time — though Blade verges on the threatening. 

Blade

One of the first generation of cool surname names, now largely used for girls in the US, but still popular for boys in its native Scotland. A prominent association for Brits is former prime minister Tony Blair, who was leader at the time of the Iraq War.

Now that such Old Testament patriarchs as Elijah and Moses fill the playground, Boaz seems downright baby-friendly, having more pizzazz than many of the others, perhaps as a successor to Noah.
 A name that was used by the seventeenth century Pilgrims and is still heard in Israel, but is a rarity in the U.S., Boaz is associated with the Jewish holiday Shavuot, as that is when the Bible story of Ruth is read in the synagogue, and Boaz was Ruth's wealthy and generous second husband, making it logical for Boaz to sometimes be given to boys born at that time.
 Extra added attraction: one of the all-time great nicknames &mdash; Bo.

Boaz

Bram has an unusual measure of character and charm for a one-syllable name; it started as a hipper-than-Abe diminutive of the biblical Abraham, but is also an independent Irish and Dutch name, made famous by Irish-born Dracula creator Bram (nee Abraham) Stoker. Bram is currently Number 16 in the Netherlands; Bram Howard was a character on The West Wing.
 Another route to Bram is Bramwell, as in early actor Bramwell Fletcher, who &mdash; speaking of horror movies &mdash; was noted for his mad scenes in the 1932 film The Mummy.

Bram

Rugged and straightforward brand-new name, though you might not like the idea of branding your son.

Brenner is an occupational surname for both a charcoal burner and a distiller of spirits. One of the least used of occupational surnames, it has that 'er' ending that definitely adds to its stylishness; a possible successor to Brendan.

Brock is a rock solid name, with a touch of preppy sophistication. It ranked solidly in the 200s-300s from 1975 until 2014, but has since tumbled a bit.
 Among Brocks who lived up to their name are Brock Peters (actually born George), who played Tom Robinson in To Kill a Mockingbird; Brock Pemberton, a founder of the Tony Awards; and Brock Chisholm, the first director-general of the World Health Organization.
 Brock is the traditional name given to a badger in folk tales.

Bruce is a Norman place name made famous by the Scottish king Robert the Bruce, who won Scotland's independence from England in the fourteenth century. It's perennially popular in Scotland, but has been rarely used here for a generation -- though the impact of Bruces Lee, Springsteen, Dern and Willis, as well as Batman's Bruce Wayne -- still lingers. At one time Bruce was so widespread in Australia, it became a nickname for any Ozzie man. An interesting alternative is Brix, the Normandy place name where the Bruce family originated.

Bruce

Bruin is the Old English term for bear, taken from the Dutch word meaning brown.  Bruin might be a sports fan's choice or an animal name in hiding.  As a kind of hybrid of Roone and Bruno, it's definitely got some cool.

Bruin

The simple and attractive Bryn is well used for boys in Wales, and does have a history as a male name in the US, although both Bryn and Brynn are currently far more popular for girls.

 Fans of British TV sitcom Gavin and Stacey will recognize it as the name of Stacey's lovable and eccentric uncle, played by Rob Brydon.
