Alda's brother name Aldo has been a mainstay of the U.S. popularity chart for decades now, and the related Alden is soaring up as well. This version has never really caught on. (Maybe it's the association with Alan Alda: great actor, unlikely namesake for a little girl.) However, there is possible hope now that Alba and Alma are on the rise. Aida and Arden are more familiar alternatives.

Alda

Asherah is probably one of the most ancient of mother goddess symbols, recorded in the pantheons of several civilisations from the tenth century BCE. As the mother to innumerable gods and goddesses, she is often depicted as having the capacity to walk on water, which makes Asherah an excellent choice for a baby born under one of the water signs of the zodiac, including <a href="https://nameberry.com/blog/zodiac-baby-names-its-scorpio-season">names for Scorpio babies</a>, as well as those born under Pisces and Cancer.

A popular name in Denmark, in this country Bo has some cowboy swagger and a lot of substance in its minimal two letters.
In Mandarin Chinese, Bo means "wave".

This tiny but punchy name has multiple origins. It stands strong alone, but could be short for numerous names including Bonnie and Bodhi.
In Mandarin Chinese, Bo means "wave".

The beguiling Darya is the name of a character in Tolstoy's Anna Karenina. As a Russian name, it's a spelling variation of Daria, while in Iran, it's a girl's name that means "the sea".

Dylan still feels poetic and romantic after years of popularity. It still ranks highly on the charts, among the top <a href="https://nameberry.com/search/boys-names/d">boy names starting with D</a>, so if you choose it, be aware that yours may not be the only Dylan in his class. 
 
Dylan was derived of the Welsh components dy and llanw, meaning "sea." In Welsh mythology, Dylan was a legendary sea god who prompted all the waters of Britain and Ireland to weep when he died. The name came to prominence via the great Welsh poet Dylan Thomas, whose name Bob Dylan adopted in tribute.
 >Several celebrities have sons named Dylan, including Welsh-born Catherine Zeta Jones and Michael Douglas, Kenneth 'Babyface' Edmonds and Nadia Comaneci.
 The name Dylan was given to about 500 baby girls last year, but 7000 baby boys so it doesn't quite qualify as unisex. 
 Dillon is another popular spelling, though the Dillon spelling is used only about 5 percent of the time.

Dylan

A unisex name in Israel but in the U.S., it might as well be Sue.

This unisex Israeli name, which rhymes with ball, is sure to receive more serious international attention now that actress Gal Gadot is the new Wonder Woman.

Kai is an internationally flexible name with many possible origins and meanings, growing in popularity in the US and a diverse range of European countries.
 
In the US, the name Kai is most commonly referred to as being of Hawaiian derivation, meaning "sea." In Europe, Kai is largely considered to have Frisian origin as a diminutive of the name Kaimbe, meaning "warrior", or as a short form of Gerard "brave spear". 
 
Kai is also found as an independent name in African, Chinese, Turkish and Native American cultures. Kai is a strong, evocative multi-cultural name that packs a lot of power in its single syllable. 
 
Famous as the name of the boy enchanted by the fairy-tale Snow Queen, Kai was chosen for her son by actress Jennifer Connelly and as a middle name for son Samuel by Naomi Watts and Liev Schreiber. 
 
Kai is popular with Berries as both a first and middle name choice. Perhaps because of its international familiarity, Kai is popular in video games. Its most prominent namesake is Danish-born jazz trombonist Kai Winding.
 
Kai ranks in the US Top 1000 for girls, but is used more than 90 percent of the time for boys. Donald Trump, Jr. has a daughter named Kai Madison and Gigi Hadid and Zayn Malik named their daughter Khai in 2020.

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 Hawaiian name gracefully celebrates the force of nature, paying tribute to the ocean. If you're looking for unique <a href="https://nameberry.com/list/641/names-that-mean-ocean">names that mean ocean</a>, this should be on your short list.

Lainey is one of the many fast-rising nickname names of the last few years, and longer forms like Elaine, Alaina, and Delaney are enjoying their own bouts of popularity. Simple and tailored, but equally sweet Laine is not yet in the Top 1000, but feels stylish today.
 
As an Estonian and Latvian name, it is a word name connected to the ocean, but also pronounced with two syllables as LIE-neh.

Laine

Llyr is a name with a great meaning and a lovely sound, but that sound is going to be next to impossible to get non-Welsh speaking people to pronounce (google the double L sound in Welsh). If you are outside Wales, you may wish to consider the Irish alternative Lir, which has the same meaning and an easier sound. 

Llyr

A name with many spelling variations, including Malek, Melik, and Maliq, Malik is a popular name of Arabic and Semetic origin that is used internationally as both a given name and a surname. In terms of meaning, it can be considered a royal name meaning "king", though other sources suggest it is an alternative transcription of Maalik, making "owner, possessor" a more accurate meaning. 
 
In Islamic tradition, al-Malik is one of the 99 names of Allah, meaning the name is used by Muslim families across the world. It ranks in the Top 400 in the US and the UK, while in France, Switzerland, and Quebec it is in the Top 100. 
 
From an entirely different root, Malik may also be considered a nature name. In Greenlandic, it means "sea, wave" and was a popular choice in the 2000s.

Malik

The Spanish and Portuguese word for "sea" is a Top 100 name in Spain. In America, it's sometimes used as a nickname for names like Martina and Marina, but it could also plausibly stand on its own.

Marinus

Maris is an unusual and appealing name that has never appeared in the U.S. Top 1000, overshadowed by its twentieth century elaboration, Marisa/Marissa. It derives from the phrase "Stella Maris," star of the sea, one of the many epithets of the Virgin Mary, and became familiar via the unseen (but unliked) character of sitcom Frasier's ex-sister-in-law.
 
As a surname, Maris is associated with legendary NY Yankee, Roger Maris.

Maris

Marisol is a favorite <a href="https://nameberry.com/baby-names/495/spanish-names-for-girls">Spanish name for girls</a>, and an excellent candidate to cross the culture line, a la Soledad and Paz. 
 The striking French-born Venezuelan artist Marisol Escobar—known simply by her first name—is noted for her witty Pop Art figural sculptures.
 While the name comes from a title of the Virgin Mary—Our Lady of Solitude—it's also associated with the Spanish words for sea and sun, mar y sol. The meaning of Maria is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Marisol

One of the many names for the Virgin Mary, this name is popular in Spanish- and Portuguese-speaking communities.

Maristela

Mary is the English form of Maria, which ultimately was derived from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

 Mary, the quintessential New Testament name, was #1 for girls until the mid-twentieth century. Though still popular, Mary is used now mostly for religious or family reasons. If it's style you're after, Mary's many diminutives and derivatives such as Maire, Mamie, May, Mitzi, Molly, Maura, Marietta, and even Maria may seem more fashionable. 

 Mary was the most popular and enduring female Christian name in the English-speaking world (as were Maria and Marie in Spanish and French) until the 1940s. That was when in the US Mary was finally dethroned by such trendy upstarts as Linda and Karen.

 There are six Marys in the Bible, including the Virgin Mary, Mary Magdalene, Mary the sister of Martha and Lazarus, Mary the mother of James and Joseph, and Mary the mother of Mark, and there have been British royal Marys beginning in the sixteenth century. In earlier times Mary was considered too sacred to be used; it finally gained usage in England in the twelfth century, and by the sixteenth had blanketed the female population, to the point where dozens of pet forms had to be contrived to distinguish one Mary in the family from the others.

 The poet Byron deemed Mary a "magic" name, and Bing Crosby proclaimed it "a grand old name." Mary has always been a good-girl name, as reflected by such mid-century icons of propriety and wholesomeness as Mary Poppins and Mary Tyler Moore. The lovely Lady Mary Crawley of Downton Abbey has restored some freshness to the name.

 Among the celebs who dropped their birth name of Mary are Meryl Streep, Debbie Reynolds, and Lily Tomlin.

Mary

A medieval Cornish name which despite sounding similar to the French name Emeraude, is actually connected to the Welsh name Morfydd. Pronunciation rhymes with Herod -- and yes, the final d is pronounced.

Meraud

Meredith has been considered primarily a girl's name since the fifties, before which it was more commonly used for boys. Comic actor Jay Mohr recently named his son Meredith, which might help it swing back into the blue column. The traditional Welsh pronunciation puts the stress on the middle syllable, making Red a cool nickname possibility.

Meredith

Meredith is a soft, gentle-sounding name with subtle Welsh roots. Although originally a <a href="https://nameberry.com/boys-names">boys’ name</a>
, Meredith is used mainly for girls now.
 Meredith's highest point of popularity for girls in the U.S. was in the late seventies and into the eighties, when it ranked as high as Number 140.
 Meredith, when said with the American and English pronunciation, offers the delightful "Merry/Merri" as a nickname. Be aware, however, that the correct Welsh pronunciation has the emphasis on the second syllable (muh-RED-ith), making "Reddy" a more suitable nickname.

Upbeat name that cheers you as soon as you hear it. One famous bearer is Maori feminist Meri Te Tai Mangakāhia. 
 As Finnish name, it is connected to the sea.

Meri

This name of the famous fifth-century sorcerer and mentor of King Arthur may or may not be a bit wizardy for a real-life modern child. Its most noted modern bearer: football star turned actor Merlin Olsen, whose father was named Merle.

Merlin fell off the US Top 1000 half a century ago, though it ranks in the Nameberry Top 1000, which could be a harbinger of its return. About 50 baby boys were named Merlin in the US last year, and about ten girls. It is used in contemporary Germany.

Merlin

This name owes its present life to actress Sorvino. Mira and Mirra have an arty aura. 
 
Mira is a true cross-cultural choice, with the literal meaning of "look" in Spanish, a peaceful meaning in several Eastern European languages, a well-used name in Arabic cultures meaning queen-like or a female ruler, and a nature name in Sanksrit. In Greek, it means "fate, destiny". 
 
Mira can also be a short form of Miryam or Miranda.

Mira

This Maori name, often heard in New Zealand, is an attractive, evocative choice for lovers of the ocean made famous – perhaps too famous – by the Disney heroine. Moana was also an alternate name for the heroine Ofelia in Pan's Labyrinth. Moana may also be a color name for a deep ocean blue ("lanu moana"). Moana and other <a href="https://nameberry.com/blog/disney-princess-names">Disney Princess Names</a> are the subject of a featured blog.

Moana

Morgan, once split evenly between the sexes, is a strong and attractive Welsh favorite, still a common <a href="https://nameberry.com/boys-names">boys’ name</a> in Wales. Morgan is now more often a girls' name in the U.S. – about 2000 girls were given the name in one recent year, vs. 362 boys – though it's one of the most traditional unisex choices. Morgan was actually a Top 200 pick for boys in Victorian Britain!
 Distinguished actor Morgan Freeman is a worthy male namesake.

Morgan

Morgan has long been a traditional Welsh male name, a variant of the Old Welsh name Morcant, from the Welsh elements mor, meaning "sea" and cant, "circle." The female Morgan is unrelated to the male version—it is a name from Arthurian legend created for Morgan le Fay, King Arthur's half-sister and famed sorceress. Her name comes from Morgen, an Old Welsh name meaning "sea-born," and is related to the Irish name Muirgen. 
 
In this country, Morgan is now used more for girls than boys, though considerably lower than its Top 25 status in the 1990's. And although it's been veering south for both sexes, we still find Morgan a sophisticated choice. 
 
Actress Morgan Fairchild—who had an influence on the name's popularity for girls—was born Patsy.

A common family name in Scotland, occasionally used as a first. 

Muir

Muirgen in Irish mythology was turned into a mermaid and then brought back to land after 300 years and transformed back into a woman -- which must have been quite a shock.  Muirgen's original name was Liban.  Muirgen may also be spelled Muireann or Muirenn.

Murchadh

A multicultural option that's equally intriguing but more unusual than Maia. Connected to water and the ocean, it is a Top 100 choice in Spain and Puerto Rico and has been rising up the charts in France and the UK in recent years. Alternative (and equally multicultural) spelling alternative Nya has also proved popular. 

Naia

This Roman mythology (and planet) name would be very hard to handle. It derives from a root meaning cloud.

Neptune

More intriguing than the more familiar form Nerida, this name is perfect for a beach baby, or a baby born under a water sign.

Nereida

The name of the father of the sea nymphs is derived from the Greek neros meaning "water" and was borne by a 1st century Roman saint. A sea-inspired choice, Nereo is an alternative form, used occasionally among Italian and Spanish speakers. 
 
A rare choice, Nereo has only appeared in the US charts a handful of times. Notable bearers however include footballers Nereo Champagne and Nereo Rocco, and journalist Nereo C. Andolong "Nering".

Nereo

The name of the father of the sea nymphs -- or one of its shorter forms such as Nereo or Nerio -- would be somewhat easier for a child to carry than Neptune. The name Nereus is largely forgotten but it certainly could rise again along with Atticus and Cassius and other ancient Greek brethren.
 It derives from the Greek neros meaning "water" and was borne by a 1st century Roman saint, making it both a saint name and a sea-related choice. The traditional Greek pronunciation has two syllables while the English form has three. 
 
The name has never charted in the US, but its Spanish and Italian form Nereo has occasionally been used.

Nereus

An offbeat possible replacement for the overused Melissa and Marisa, Nerissa was used by Shakespeare for Portia's witty confidante in The Merchant of Venice. Queen Elizabeth has a cousin named Nerissa.

Nerissa

Pronounced to rhyme with fjord, the Norse god of the sea's name, this would make an unorthodox choice for sea-lovers and fishermen.

Nature names like Ocean and River are flowing back into favor, especially with nature lovers and green-oriented parents. 
 Forest Whitaker, an inspired child namer (his other kids are called Sonnet and True), has a son named Ocean Alexander.
 Variations include Oceanus, the name of the child who was born during the voyage of the Mayflower, and Oceane, a wildly popular girls' name in France.

Ocean

Ocean is a nature name that comes right out and states its meaning and association. Full of power and depth, Ocean is one of the fastest-rising baby names for both girls and boys, making the US Top 1000 for both genders in 2021. Oceane, the version that's trendy in France, was used for only 11 baby girls in the US in the same year.

Ocean-lovers who want to be less obvious can choose such subtler <a href="https://nameberry.com/list/641/names-that-mean-ocean">names that mean ocean</a> as Jennifer or Marissa, but coming right out and using Ocean is a perfectly valid way to go.

Oceane (oh-see-EN) has been one of the chicest names in France for several years, ranking in the French Top 50. This is a sophisticated name that could easily cross the ocean, and is much more stylish than the English Ocean or Oceana.
 This group of names all relate to the ancient Greek Oceanus, god of the open sea and the oldest Titan, son of Uranos and Gaia. If you're looking for uncommon <a href="https://nameberry.com/list/641/names-that-mean-ocean">names that mean ocean</a>, this is one to consider.

Oceane

One of those names with a wide array of meanings across different cultures; it's the Lithuanian form of Anna, for instance, and William Blake used it as the name of one of his mysterious, godlike characters. But it's found major popularity in Spain, where it's just outside the Top 50. It makes the Top 10 in Catalonia, being both a diminutive of Mariona and the word for "wave".

Okeanos

Pelagius

This Roman name is featured in the New Testament as that of the governor of Judea.

Pontius

This version of the sea god's name may be more ready for prime time than the Roman version, Neptune -- slightly. 

Poseidon

Pontus

Proteus

Despite appearances, Rosemary is not a "smoosh" name, not even a traditional one. The name derives from two Latin terms "Ros" meaning ‘dew’ and "Marinus" "meaning "of the sea". The plant was termed ‘dew of the sea’ due to its salty texture and its ability to thrive in coastal climes. Only after the Middle Ages did the English names of Rose and Mary become interchanged with the name Rosmarinus and give us the modern name we use today.
 In ancient legend, Rosemary was draped around Aphrodite when she rose from the sea. It was regarded then as beneficial in strengthening the memory and became a symbol for faithful lovers. In Hamlet, Ophelia says "There's Rosemary, that's for remembrance; pray, love, remember."
 The name was long associated with George Clooney's aunt, the great pop singer Rosemary; less pleasant associations are with the 1967 movie Rosemary's Baby.
 A common variation is Rosemarie; many parents are now looking to the stand-alone nickname Romy.

Rosemary

Reidun

The name of the Inuit goddess of the sea, marine animals, and the underworld. There is also a dwarf planet in the outer solar system called 90377 Sedna, discovered in 2003 and named after the goddess because: "Our newly discovered object is the coldest, most distant place known in the Solar System, so we feel it is appropriate to name it in honor of Sedna, the Inuit goddess of the sea, who is thought to live at the bottom of the frigid Arctic Ocean."
