Like River and Lake, a cool, refreshing modern water-related choice. 

A nature name, a word name, and a surname name, Brooks has plenty of cool factor. It gives off cowboy vibes and a sporty feel, while also maintaining a smart, collected image. 
Used occasionally as a given name throughout the 20th century, Brooks gained serious attention during the 2010’s. Following fast on the heels of stylish Kai and classic Jack, Brooks is now in the US Top 100. 
Derived from the English surname Brook, meaning “one who lives near the steam”, Brooks could appeal to anyone who wants an outdoorsy <a href=“https://nameberry.com/list/756/best-nature-names-for-boys”> name connected to nature</a> and to those enjoy the sleek, smart trend of <a href=“https://nameberry.com/list/358/surname-baby-names”>surnames as first names.</a> 
While it might feel very contemporary, Brooks has made its mark on history. Brooks Calbert Robinson played for the Baltimore Orioles from 1955 to 1977 and is considered one of the greatest third basemen ever. Other notable namesakes include: Brooks Atkinson an influential theatre critic; Brooks Betts, the guitarist of rock band “Mayday Parade”;E. B White, the author of Charlotte’s Web, who was born Elwyn Brooks; and Brooks Harris, a physicist. 
With a more masculine slant than Brooke or Brooklyn, Brooks is given to over 4000 boys each year. It could be set to rise higher in the charts over the coming years, so if you enjoy the cool, surname-y style, you could also consider Boone, Wilder, Mack, Adair, Boyd, and Briggs as less popular alternatives.

Artistic associations with the sculptor who invented the mobile make this one of the more creative surname choices.

Cove is an up-and-coming nature name whose cool sound and peaceful image saw it rising for both sexes... until COVID-19 hit. It remained steady in use for boys in 2021, but actually increased for girls, although it remains a seriously rare and distinctive choice for either gender. 

Cove

Finn is a name with enormous energy and charm, that of the greatest hero of Irish mythology, Finn MacCool (aka Fionn mac Cuumhaill), an intrepid warrior with mystical supernatural powers, noted as well for his wisdom and generosity. 
 Finn was chosen by cool couple Christy Turlington and Ed Burns for their son, and also by Jane Leeves and Autumn Reeser. Played by Cory Monteith prior to his death, Finn Hudson was a prominent character on Glee.
Other up-and-comers in the same family: Finlay and Finley, Finian and Finnian, Finnegan and Finnigan, and, from Germany, Fynn.

Another culture's take on the Hailey/Halle phenomenon.

We've seen Haven take off as a nouveau girls' name; Harbor could follow in its wake. 

Harbor

Haven is a recently invented safe-harbor name that appeals to an increasing number of parents who don't want to voyage quite as far as Heaven. 
 Haven Kimmel is the author of the bestselling memoir A Girl Named Zippy, and Haven Denney is a medal-winning skater. There was also a supernatural TV series called Haven.
 
Jessica Alba's younger daughter and middle child is named Haven, sister of Honor and Hayes. Robert Herjavec and Kym Johnson named their daughter Haven, twin of Hudson.

There are currently more than ten baby girls named Haven for every boy, though the name is equally appropriate for any gender.

Haven

Hurley is a possibility as a unisex surname-name ending with the "lee" sound. It is perhaps most associated with British actress Elizabeth Hurley, and is much rarer than Harley, because the "ur" sound is currently out of fashion (and the word "hurl" may put some off).

Hurley

Isla is a hit name throughout the English-speaking world but hasn't found the same popularity in other western countries, perhaps because its spelling and pronunciation don't make sense for those whose native language is not English. Think island without the final two letters.

Adding to the confusion, the name is a twin of the Spanish word for island, which is pronounced EES-la. Isla is part of a trend for simple, old-fashioned <a href="https://nameberry.com/girls-names">girls’ names</a> that start and end with a vowel: Ava, Ada, Ella, Emma, Eva, Ida, Ivy. 
 
Red-haired actress Isla Fisher, married to Sacha Baron Cohen, propelled the name to stardom. Isla Black Hitchens is a Harry Potter character; Queen Elizabeth has a great-granddaughter named Isla Elizabeth Phillips. 
Some other similar names that are not as trendy as Isla: Islay and Ailsa.

Isla

This appealing multi-cultural name, pronounced KYE, is beginning to be used for girls as well as boys. Among its many derivations and meanings: "sea" in Hawaiian, "forgiveness" in Japanese, "willow tree" in Navajo, "food" in Maori, and "earth" in Scandinavian. For girls, it debuted on the US Top 1000 in 2010.

This name's similarity to Kalani and pretty Hawaiian origin helped catapult it into the Top 1000 for the first time in 2013.
 Kailani Craine is an Australian figure skater.

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.
 Americans and Australians tend to pronounce the first syllable of the name like Lock, but the genuine Scottish pronunciation sounds more like Lack.
 In Ireland, the name was Anglicized as Laughlin; in Scotland the pet forms are Lach, Lachie, or Lockie.
 Lachlan has been a top name in Australia for at least a decade. It has been in the headlines recently via the eldest son of media mogul Rupert Murdoch.
 Somewhat surprisingly, Lachlan has US presidential cred, as the son of tenth president John Tyler, whose other children included Lyon, Letitia, Tazewell, and Pearl.

Lachlan

Laiken

This body of water runs deep; the best of a group of new possibilities that includes Bay, Ocean, River, and the more established Brook. It has received attention via the actress Lake Bell. Lake would make a particularly cool and refreshing middle name, as Gisele Bundchen and Tom Brady did for daughter Vivian.
 Lake is also a fairly common surname, represented by 1940's blonde femme fatale Veronica (born Constance Ockelman), actress/talk show host Ricki and Emerson, Lake & Palmer bassist Greg.

Lake

Meilani may sound like a Hawaiian name, kind of a mashup of Leilani and Melanie, but it's actually an invention by that style-maven JWoww, AKA Jenni Farley of Jersey Shore, who used it for her daughter. It debuted in the US Top 1000 in 2015.

Meilani

This Old Testament female name has been one of the most popular <a href="https://nameberry.com/girls-names">girls’ names</a> in Israel over the last decade. Also highly popular in Spain, Portugal and the Netherlands, and a new entrant to the US Top 1000, it may be misunderstood here as an attempt to streamline and feminize the more familiar Noah – although it's a separate name with a separate derivation.

 Now for the confusing bit... There is a female figure in the Old Testament named Noa or Noah, whose name derives from the Hebrew No'ah, meaning "motion". The popular Biblical male name Noah (sometimes spelled as the streamlined Noa) is derived from a different Hebrew name: Noach "rest, repose" – although confusingly they are often written the same in English. 

 Noa is the modern Hebrew spelling of the female name, but it is also found as a variant spelling of the male name Noah – popular in countries including France, Croatia and Bosnia and Herzegovina. 

 Complex backstory notwithstanding, Noa's rise to the charts indicates increased interest in this sleek moniker.

Modern surfer boy. Just don't call him Reefer.

The "Believe It or Not" jokes will get old fast, but this surname feels fun and on-trend for both girls and boys.

Ripley

Most of the notable Rivers have been male, but this nature name certainly flows as well for a girl. The name River is still rising for both genders, with about 3500 baby boys receiving the name last year vs. 1900 baby girls.

Kelly Clarkson's choice of River for her newborn daughter further raised the profile of the <a href="https://nameberry.com/girls-names">name for girls</a>. Baseball great Derek Jeter and Hannah Davis used the same name as Clarkson for their daughter born in 2021, River Rose.

River

A sweet Scottish short form of Alexander which is feeling newly appealing now the era of Sandra is far behind us. Sandy would also work well as a nickname for a child with pale red or dark blond hair.

Sandy

Saylor jumped into the Top 1000 in 2013 and is given to three times as many girls as the Sailor version. That may be because Saylor feels more like a name and less like an occupation or a word. Its spelling near-echoes the hugely popular Taylor, plus Saylor is a traditional surname in its own right. Recorded in the medieval times in Germany, it's related to the word seil which means rope and was an occupational name for a ropemaker, which also relates to sailor.

Saylor

A perfectly fine Anglo surname, though we'd prefer Keaton. Oscar-winning writer-director George Seaton (Miracle on 34th Street, The Country Girl) was actually born George Stenius.
