Can a name as virtuous as Hope be cool and trendy? Strangely enough -- yes. But though this optimistic Puritan favorite is experiencing substantial popularity, Hope is too pure and elegant to be corrupted, a lovely classic that deserves all the attention it's getting. 
 Hope, along with Faith and Charity, is one of the three theological virtues, first used as a Christian name in the seventeenth century by the Puritans. Hope and Faith have often been given to twins.
 There have been characters named Hope on four different soap operas. The TV show Raising Hope was about, yes, raising a child named Hope--formerly named Princess Beyonce. Brad Garrett has a daughter named Hope.

A name gaining recognition in Australia, based on the huon pine tree which grows in Tasmania.  Boatbuilders especially love this rare wood, which floats well, is resistant to rot, and has a strong pine-y scent.

This super-charged variation of Jett is on the rise -- along with the unlikely newcomer Jetson.

Similarity to the English name Jean could be a plus in a Japanese-American or Chinese-American family. 

June, a sweetly old-fashioned month name derived from the goddess Juno, was long locked in a time capsule with June Allyson (born Ella) and June Cleaver, but is rising again especially as a middle name. 
 June was a Top 100 name from 1915 to 1941, peaking in 1925 at Number 39. It fell off the U.S. Top 1000 in 1987 and returned in 2008 after a two-decade hiatus. Now, we'd call it one of the vintage girls' names starting with J due for a comeback. Balthazar Getty has a daughter named June and Amanda Peet used it as her daughter Molly's middle name.
 Juni is the Scandinavian version; other related choices are Junia, Juno, Juna and Djuna.

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.

Kya, a variation of the popular Kaia, the feminine form of the also-popular gender-neutral name Kai, was one of the fastest-rising girls' names of 2023.

Names starting with the ky (rhymes with by and why) sound are trending in general, with Kya along with four other names making up a full quarter of the fastest-rising names of 2023.

Lily is the most popular of the popular delicate century-old flower names now making a return, thanks to its many irresistible attributes: a cool elegance and a lovely sound, a symbol of purity and innocence, and a role in Christian imagery.
 Lily's use as a given name was a direct influence of the flower. The floral name was derived from the Latin lilium, itself derived from the Greek leirion. Lily later became an adjective to describe whiteness and purity.
 
 Lily is a favorite of celebrity parents, including Chris O'Donnell, Kate Beckinsale, Greg Kinnear, Fred Savage, and Johnny Depp and Vanessa Paradis (who made it a double bouquet, with Lily-Rose). The more proper Lillian is also rising in popularity, though Lily has long stood on its own. 
 Lily is an authors' favorite, some notable example being Lily Bart, the main character of Edith Wharton's House of Mirth, Lily Owens in The Secret Life of Bees and both mother and daughter of Harry Potter. Other current bearers are Lily Tomlin, singer Lily Allen, and actress Lily James. Two one-time starbaby Lilys are now celebrities on their own: Lily Collins, daughter of Phil, and Lily Rabe, daughter of Jill Clayburgh and David Rabe.
 Lily is currently quite popular throughout the English-speaking world as well as in France, Denmark, the Netherlands, and other European countries. Other possible spellings are Lilly, Lili, and Lillie.

Opal is on the verge of a repolishing, following other jewel names like Ruby and Pearl. A Top 100 name during the first two decades of the twentieth century, the opalescent Opal has a good chance of coming back as another O-initial option.
 The ancient Greeks believed that opals were formed from the tears of joy wept by Zeus when he defeated the titans, and that the opal bestowed prophetic powers; the Romans considered it a symbol of hope and good fortune. It was a favorite gem of Queen Victoria.
 Opal Pelis is a character in Theodore Dreiser's seminal 1925 novel An American Tragedy.
 And keeping with the O theme, Opal is the birthstone of October, making it an appropriate choice for a little girl born in that month.

Pema is related to the more familiar Hindu name Padma and means lotus flower. This delightful name was given to only 14 girls in the USA last year, so it's guaranteed to be a unique choice. Pema is probably most familiar to Westerners through Buddhist nun Pema Chodron and through Jetsun Pema, the Dalai Lama's sister. Note: Pema rhymes with Emma.

From India, but feels like an Irish surname (and can in fact be a variation of Rowan), so a possible cross-cultural choice.

Senna is a flowering bush common in the tropics, with bright yellow flowers.  In herbal medicine, Senna has gained some notice as the active ingredient in so-called "dieter's teas," which works mainly as a laxative.  While that is a less-than-savory association, Senna has a pretty sound and is a fresh entry in the flourishing botanical names genus.

Ursa might be a good choice if you're looking for a bear name for your daughter but want to avoid the She Witch curse placed on Ursula by Disney's The Little Mermaid. Too bad, because Ursula is a classic and lovely name, but Ursa has less baggage.
