Baby

After a century of association with horses and cows, this name just could be ready for revival by a fearless baby namer -- after all, it did happen to Jessie and Becky. 
 Bessie has been in use since the seventeenth century and is found as characters in Jane Eyre and in Sean O'Casey's play The Plough and the Stars. More recently, she was an animated automotive character in the movie Cars.
 On the popularity lists until 1975, Bessie was a Top 25 name from 1880 to 1906, reaching Number 9 in 1889. Notable namesakes include the great blues singer Bessie Smith, and Bessie Coleman, the first African-American female aviator.
And if you want to go more refined, you could simplify to Bess.

Bessie

Bix is a cool and jazzy nickname name, thanks to that final x. It's largely associated with the legendary and influential cornet player (and inspiration for the novel Young Man With a Horn), Bix Beiderbecke. He was born Leon Bismark Beiderbecke and his nickname derived from his middle name.
 Bix could easily fit in with cousins Jax, Dax, etc.

Among the coolest of the cool color names, particularly popular with celebs as a unisex middle name. 

Blue

This is a name you get stuck with, not (we hope) one your parents choose for you. 

Until recently it was rarely used as a proper name; Buddy Holly, for example, was christened Charles, and Salinger's Buddy Glass was born Webb. Celebrity chef Jamie Oliver did name his fourth child Buddy Bear Maurice--a fittingly named brother to Poppy Honey Rosie, Daisy Boo Pamela and Petal Blossom Rainbow, and singer Tom Fletcher has a double-nicknamed Buddy Bob.

Buddy

Bunk

An old-fashioned nickname in the Bud/Buzz/Biff mold; this one's kind of belligerent. Michelle Hicks and Jonny Lee Miller moved outside the box when they used it for their son--given the safer middle name of Timothy.

Buster

Bunny

Even for lovers of Cab (born, yes, Cabell) Calloway's music, the connection to 'Taxi!' is too strong.

Chet is an old-fashioned short form that, ala Ned and Joe, is starting to sound cool again.

While John Wayne and Duke Ellington are worthy role models, the reason Duke is currently enjoying a revival and returned to the Top 1000 in 2013 as one of the year's fastest-rising <a href="https://nameberry.com/boys-names">boys’ names</a> is more likely due to the name given to high-profile TV couple Giuliana and Bill Rancic. Christened Edward Duke, he has always been called by his middle name, just as Edward Duke Ellington was. Duke is just one of several aristocratic titles being increasingly used by ordinary citizens.

Gus is a homey grandpa nickname name that can work as a short form for any of the above or stand on its own as a cutting-edge replacement for Max and Jake--though it was off the Top 1000 from 1978 until 2016, when it squeaked in at Number 999.
 Gus was chosen for their sons by Dixie Chick Emily Robison and actress Julie Bowen. In T.S. Eliot's Old Possum's Book of Practical Cats (and in the stage musical), the full name of Gus the Theatre Cat is Asparagus.

Hoagy

The line should end with Junior Soprano. While most would expect this to be a nickname rather than an actual given name, Junior has always ranked in the US Top 1000, hitting its peak in 1925 at Number 116.

King is a name that sends a mixed message. While some might think of it as more fitting for a canine, others see it as a strong name with offbeat style and a full court of rich associations, from Dr. Martin Luther King Jr. to Elvis. 

King Vidor was an important early Hollywood director; King Camp Gillette invented the safety razor.

Spunky old vaudeville era nickname name suddenly sounds new again. 

Recently chosen by singer Elle King for her son. Lucky is a name that could see a considerable rise in the near future, as word names continue to heat up.

Mezz

Monk

Mutt

Nappy

Just the kind of old-fashioned nickname coming back into style. 

Papa

Fiery but slight middle name choice; much more apt to be a redhead's nickname. 

Ruby could be a short form of the Biblical name Reuben and especially its streamlined form, Ruben. As a gemstone name, it's currently enjoying a fresh boom of popularity for girls – nearing the US Top 50 for the first time in almost a century. 
Despite its two waves of popularity for girls, it has been occasionally used for boys since the 1890s. Since Ruby re-entered the US Top 100 for girls in 2011, nearly 70 boys have been bestowed the name.
 
While Ruby isn't likely to become a (statistically) unisex name just yet, as softer options like True, Ari, Robin, Casey, Alby, and Tatum come into style, perhaps a few more parents will consider it?

Ruby

Sonny is one of the generic boy nickname names making a surprise reappearance, and it was recently used by actor Jason Lee. Another surprise: It's been on the US Top 1000 list every year since 1927, reaching a peak in 1975, when it hit Number 428.
 Most celebrities who've gone by Sonny have had a formal birth name, including Sonny Bono (born Salvatore), Secretary of Agriculture Sonny Purdue (George Ervin), boxer Sonny Liston (Charles), and jazz musician Sonny Rollins (Theodore Walter). Even fictional Sonny Crockett on Miami Vice was born James.

Sonny

Spike is part mid-century nickname-name, ala Buster or Buck, and part word name, with an all-over cool creative dude feel thanks to directors Spike Lee and Spike Jonze. Mike Myers named his son Spike. That's right: Spike and Mike. Spike qualifies as one of the distinctly <a href="https://nameberry.com/list/519/american-baby-names">American names</a>.

An approachable mini name that could go on the birth certificate, but may work best as a nickname. Full name options include Thaddeus, Theodore, and Thomas, which was the given name of Abe's son Tad Lincoln. Taddy is a rare alternative to Teddy.

Thad is a tad too slight to stand alone as a name, though as a short form of the imposing Thaddeus it's as serviceable as Ted or Ed.
