This name's buttoned-up British vibe is what makes it cool - that, and the fact that it was chosen by Anne Bronte as her pseudonym - Acton Bell. That's quite the literary - and may we add feminist - credential for a name. For those with an adventurous edge, Acton is one of the highest peaks in Antarctica.

Caledon, the name of the arrogant Billy Zane character in "Titanic," is an Irish place-name related to Caledonia, the Latin word for Scotland thought to be derived from the ancient Celtic word for "hard."  Cal is a wonderful nickname, and Caledon an inventive way to get there.

Dawson was scarcely heard as a first name before the debut of Dawson's Creek in 1998, at which point it leaped up more than 550 places in one year. The character Dawson Leery, played by James Van Der Beek, was a teen favorite until the show's demise in 2003.
 An offshoot of the David nickname Daw, Dawson could make a nice tribute to a namesake David. Also a common surname, there have been noted Dawsons from footballer Len to actress Rosario to the Leonardo Di Caprio character in Titanic, Jack Dawson.
 In literature, Dawson Fairchild is a novelist character in William Faulkner's second novel, Mosquitoes.

Florence is back, returning to the US Top 1000 girl names in 2017 after a nearly 40 year absence. Other English-speaking countries have been quicker to welcome Florence back into fashion. 
 
The name has a lot going for it, both for its floral feel and as a place name connection to the lovely Italian city (after which Florence Nightingale was named—it was her birthplace). The association to the city seems to be helping Florence stir back to life, along with cousin Flora.
 The band Florence + the Machine, headlined by red-haired Florence Welch, has also helped to rejuvenate its image.
 Florence was most popular in the US at the turn of the last century and in the early decades of the twentieth—it was in the Top 10 from 1886 to 1906. 
 Florence has a diverse mixture of namesakes and references—a character in Dickens's Dombey & Sons, a US First Lady (Harding), one of the Supremes, the Brady Bunch's Henderson, track and field star Florence Griffith Joyner, and several TV characters.
 Florence has some particularly lively nicknames—Flo, Flossie, and Florrie.

As Harrison is to Harry, Garrison is to Gary: both of the longer versions sound more modern and appealing. NPR's Prairie Home Companion's Garrison Keillor was born Gary.

Garrison

Irish surname derived from the name Gairbhín, a diminutive of garbh, "rough". It's barely been used as a first name, but could be a similar-yet-different alternative to names like Nolan and Sullivan.

Gibson is an undiscovered patronymic surname, with some appealing nicknames. It also brings to mind the popular brand of guitars.
 Though rarely heard in front place, Gibson is a popular surname that has been dotted across popular culture—think actors Mel and Thomas, buckaroo Hoot, tennis champ Althea, baseball stars Josh and Kirk, and the illustrator famed as the "Gibson Girl" creator, Charles Dana Gibson.

The girls have Violet and Scarlet and Ruby and Rose, but for the boys there's a much more limited palette of color names. Grey/Gray is one exception, which could make for a soft and evocative—if slightly somber—choice, especially in the middle. Kaitlin Olson and Rob McElhenney named their son Leo Grey. 
 A common surname, Grey/Gray is still an unusual first name choice (it entered the Top 1000 for the first time in 2013), while longer forms Grayson and Greyson are climbing rapidly. Grey is a color associated with the sign of Virgo, so Grey, Gray, and Grayson are perfect <a href="https://nameberry.com/blog/zodiac-baby-names-ideas-for-your-virgo-babe">names for Virgo babies</a>.
 The best known bearer of the name, former Governor Gray Davis of California, was born Joseph Graham Davis, Jr, and others with Grey/Gray names include Graydon Carter, editor of Vanity Fair, and Grayer, the child in The Nanny Diaries.
 It's worth noting the connection to Christian Grey, of E. L. James's Fifty Shades of Grey. Do with that what you will.

Helen is a name that has connoted beauty since ancient times – Helen of Troy was the the mythological "face that launched a thousand ships," over whom the ten-year Trojan War was fought. 
 

The name Helen has moved in and out of favor over the centuries, often alternating with Ellen. It was a Top 5 name for several decades of the early twentieth century, falling out of the Top 100 in the 50s. Now, after being unfashionable for decades, we see signs of a comeback for Helen—it's the kind of serious, unadorned classic many parents are returning to.
But if Helen still feels too plain for you, you might consider one of its many lovely variants: Helena, Elena, Eleni, Ella, Nellie or Nell, to name just a few.

 In Greek myth, Helen is the daughter of Leda and Zeus, who came to her mother in the form of a swan. Helen also has legions of real-life namesakes, including author and activist Helen Keller, politician Helen Gahaghan Douglas, newspaper reporter Helen Thomas, Cosmo force Helen Gurley Brown, Bridget Jones creator Helen Fielding, artist Helen Frankenthaler, and actresses Hayes, Mirren, and Hunt. Beatrix Potter's birth name was Helen.

Although Maguire is such a prominent Irish surname &mdash;it ranks in the Top 40 in the Emerald Isle &mdash;this lively and cheerful family name has rarely been used as a first, unlike more familiar examples like Ryan, Riley and Reagan.  The powerful and distinguished Maguire clan was known for their courage, leadership and resilience.  The name's many notable associations include the unionizing Pennsylvania coal miners known as the Molly Maguires, actor Tobey Maguire and Dixie Chick Martie Maguire. Other spellings are McGuire and McGwire; two other handsome Irish surnames to consider are Malone and Magee.

Tully is a relaxed, rarely used Irish surname possibility. Sources disagree on the meaning, depending on what root is used. The Irish tulach means hill or mound, while tuile means flood.

Statesman Alexander Hamilton used the pen name Tully when he wrote editorials denouncing the instigators of the Whiskey Rebellion.
 The ancient Irish name Tuathal, which is translated as Tully, was given to many Irish kings and heroes.
