Asher—an excellent, soft and sensitive Old Testament choice—is a <a href="https://nameberry.com/boys-names">baby boy name</a> on the rise, and is a Nameberry biblical favorite. 
 
Asher's ascent is especially amazing given that the took a century-long hiatus from the Top 1000, from the 1890s until it reappeared in the 1990s. Asher has been in the US Top 100 for more than a decade now.
 
In the Bible, Asher was one of Jacob's twelve sons who gave their names to the tribes of Israel. Asher is derived from the Hebrew word osher, which means "happiness." Rabbinical scholars claim that the Asherites lived up to this meaning, as they had the most oil, wisdom, and male children compared to the other tribes.
 
The novel My Name is Asher Lev by Chaim Potok, often taught in schools, is the story of a New York Hasidic Jewish boy with artistic aspirations.
 
Oh—and another plus for Asher: the handsome diminutive Ash.

Aurelia is an ancient Roman name that's become a surprise hit in the contemporary world. A top favorite on Nameberry, it reentered the US Top 1000 in 2014 after a 70-year absence and continues to climb.
 
Aurelia is the female form of the Latin name Aurelius, an ancient Roman surname. Aurelius is derived from the Latin word aureus, meaning "golden," which was also the name of a gold coin used in Ancient Rome. Aurelius was a cognomen, a third name in Roman culture that often referenced a personal characteristic or trait, likely used for someone with golden hair.
 
The Roman classic Aurelius, from which Aurelia derives, was very common in the Roman Empire and is currently experiencing a resurgence in the US—it re-entered the Top 1000 list in 2012 after a 61-year hiatus. 
 
The name of several minor early saints, Aurelia's sound and feel can be credited for it being on the rise again. Aurora and Oriana are Aurelia cousins you might also want to consider. 
 
Aurelia was the name of the mothers of Julius Caesar, the writer Sylvia Plath, and Arnold Schwarzenegger, who, in her honor, made it one of his daughter Christina's <a href="https://nameberry.com/list/673/middle-names">middle names</a>.

Although feminizations ending in "ette" are not particularly popular now, Bernadette is a pleasant, feminine, but strong name that doesn't feel prohibitively dated. And though strongly associated with the saint who saw visions of the Virgin Mary—Saint Bernadette of Lourdes—it is now no longer strictly inhabiting the Catholic diocese. 
 Bernadette was much more widely used at one time than it is now. The year after Saint Bernadette was canonized, her name reached Number 252, and not long after the successful film The Song of Bernadette was released, it hit Number 188 in 1946.
 Bernadette Peters is a contemporary bearer, and Minnie Driver's breakthrough film role was as Bernadette "Benny" Hogan in Circle of Friends.

Historically a diminutive of Wilhelmina, Elma's parent name and soundalike sisters are slowly stirring back to life as the trend for vintage baby names continues. With Alma on the rise in the US, Thelma chic in France, and Selma hot in Scandinavia, Elma could be in with a shot at a revival – especially given the popularity of Emma and Ella. But Muppet Elmo and Looney Tune Elmer Fudd may cast a long shadow.

It feels like Finch should be a modern bird name that's as popular as Wren or Lark, but that's not the case - so it's one to consider if you're looking for a nature name that's familiar but rare. 

These colorful birds have made big contributions to science: the Galápagos finch played an important role in forming Darwin's theory of evolution, and the zebra finch has helped our understanding of how birds learn songs. 

Finch is also a surname belonging to, amongst other admirable people, the family in To Kill a Mockingbird.

Hazel has a pleasantly hazy, brownish-green-eyed, old-fashioned image that more and more parents are choosing to share. Former Old Lady name Hazel reentered the popularity lists in 1998 and now is near the top of the charts.
 
Hazel is a name that comes from the English word hazel, referring to the hazelnut tree. The word was derived from the Old English hæsel of the same meaning. Historically, a wand of hazel symbolized protection and authority.
 
When Julia Roberts named one of her twins Hazel in 2004, there was a great public outcry against "another one of those nutty celebrity names", though we saw it as the deserved revival of a lovely vintage name with roots in nature. Hazel was one of the botanicals that were all the rage at the turn of the twentieth century, when it was in the Top 25, then fell out of favor, off the list completely from 1976 to 1998.
 
Other celebrities with daughters named Hazel include Emily Blunt & John Krasinski, and Taylor Neisen & Liev Schreiber.
 
Hazel Motes is the protagonist of Flannery O'Connor's 1952 novel Wise Blood, and In The Hunger Games, one of the characters is the variant Hazelle. But the most influential Hazel of recent years is the heartrending heroine of Fault in Our Stars.

Hazel

This unusual Greek flower and color name has gained considerable recent attention via actress Ione Skye, who is the daughter of sixties folksinger Donovan.
 Ione was one of the fifty sea nymphs — Nereids — in ancient Greek mythology.
 Parents attracted to newer I-names like Isla might want to consider the distinctive Ione. The English pronunciation usually starts with the long I, while in the Latin languages such as Italian it starts with the long E sound.

Ione

Jessamine, a charming name occasionally heard in England, is just beginning to be appreciated in the U.S. as a possible successor to all the Jess names of the past. It's also spelled Jessamyn, as in Quaker novelist Jessamyn West, author of Friendly Persuasion--who started life with Jessamyn as her middle name.
 Jessamine began to be used as a first name in Britain around 1900, along with other flower-related names. Yasmin and Yasmine are other Jasmine variations.
 This would make a great choice as a namesake honoring a Jessica.

Jessamine

Juniper is a fresh-feeling nature name -- it's a small evergreen shrub -- with lots of energy. A new favorite of fashionable parents, Juniper joins such other tree and shrub names as Hazel, Acacia, and Willow. 
 
Juniper has an interesting variety of associations -- it's mentioned in the Old Testament, was used in Renaissance paintings to represent chastity, has berries used to flavor gin, and Juniper is the Saint of Comedy. A male St. Juniper was a follower of St. Francis of Assisi. 
 Goodnight Moon and The Runaway Bunny author Margaret Wise Brown sometimes used the pen name of Juniper Sage. And in the Junie P. Jones kids' books, Junie's full name is Juniper Beatrice. There also have been Junipers is cartoon series (The Life and Times of Juniper Lee) and comic strips as well.
 
The name got something of a hippieish vibe via the 1969 hit Donovan song, 'Jennifer Juniper.'
 
Juniper entered the U.S. Top 1000 for the first time in 2011 and has risen to the Top 150.

Juniper

Long popular in Ireland and England, Kieran, the name of Ireland's first-born saint and twenty-five other saints, has been building its U.S. fan base thanks to its strong and attractive sound, and its fashionable Irish brogue. While Ciaran is the more authentic Irish spelling, Kieran is more popular this side of the Atlantic. 
 Julianna Margulies chose Kieran for her son, and Kieran is a Culkin brother to Macaulay and Rory. Kier is an attractive short form, and Kiera/Keira is Kieran's girl twin.

Margot is suddenly a star again. After a nearly-half century absence, it hopped back on the Top 1000 list in 2013 and is on the rise. The Margot spelling is now given to three times as many baby girls as the Margo one.
 Makes sense, as Margot is a name that has a lot going for it: spelled with or without the final 't', it's one of the few <a href="https://nameberry.com/girls-names">girls’ names</a> with the dynamic o-ending sound; it's familiar, yet uncommon enough to be distinctive.
 
Margot originated as a French pet form of Marguerite, a name that ultimately derived from the Greek margarites, meaning "pearl." Other spellings include Margo and Margaux. Margaux Hemingway was originally Margot but changed the spelling to honor the wine from the French village of Margaux that was drunk by her parents on the night she was conceived.
 Movie buffs will remember Bette Davis's archetypal role as Margo Channing in All About Eve (the actress named her own daughter Margot), while balletomanes will associate the name with the great English dancer Margot Fonteyn (born Margaret).
 In the film Margot at the Wedding, Margot was played by Nicole Kidman; in The Royal Tenenbaums, Gwyneth Paltrow was Margot T. Gorgeous Australian actress Margot Robbie has made an impact here in the film The Wolf of Wall Street.

Olive is one of only four <a href="https://nameberry.com/search/girls-names/o">girl names starting with O</a> on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen. 
Olive has positive associations to the olive branch as a symbol of peace and the ancient olive wreath that celebrated success.
 Olive was the name of the adorable Abigail Breslin character in the popular movie Little Miss Sunshine. Olive Chancellor is a major character in Henry James's The Bostonians and Olive Kitteridge is a Pulitzer Prize-winning Elizabeth Strout novel that was adapted into a TV miniseries in 2014. Kids might be familiar with Olive the Other Reindeer.
 Olive came into fashion at the end of the nineteenth century along with other botanical names, when it had a run in the Top 100.

No, the pronunciation--ro-SHEEN--isn't immediately obvious to the non-Gaelic viewer, but the sound of this shiny Irish version of Rose is pretty enough to make it worth considering.

A fabled storybook name via the heroine of Sir Walter Scott's novel Ivanhoe (1819), which featured a heroine called Rowena of Hargottstanstede, and also a Harry Potter name, as Rowena Ravenclaw, founder of one of the Hogwarts houses.. Rowena has some old-fashioned charm, though most modern parents seem to prefer Rowen. Pronunciation, however, is NOT like Rowen with an a at the end, but with a long e and an emphasis on the middle syllable.. She was on the popularity list until 1963, several years in the Top 500.

Rowena

Senna is a flowering bush common in the tropics, with bright yellow flowers.

One caveat though: in an Italian-American family it would be strange to have a baby named Aunt.
