Adelina is back in the Top 1000 after an absence of nearly a century, thanks to the meteoric rise of her sister name Adeline -- along with Adelaide, Adele, and Ada. Some parents choose Adelina because they want to get to cute vintage nickname Addie, but others favor it as a slightly more unusual form of this sweet vintage girls' name. A lot of attention was focused on it recently via the women's figure skating gold medal winner at the Sochi winter olympics--Adelina Sotnikova.
While Adeline is usually pronounced in the U.S. with a long i in the last syllable, to rhyme with mine, Adelina is pronounced with the long e sound at the end, as in 'lee-na'.

Celestine is a pretty, crystalline extension (actually a diminutive) of Celeste that would make a choice that is both delicate and strong. It is also a popular name in France.
 Celestine was the name of painter Edgar Degas's Creole mother. Some people might associate it with the 1993 spiritual novel "The Celestine Prophecy."
 Celestina is another attractive version.

Elina is one of the many variations of mother name Helen to make the Top 1000 list, this one just squeaking on. This is an appealing name but you may find it too similar to too many other names from Elena to Alina to Helena.

The lyrical and melodious Elodie, a Nameberry favorite, is starting to rise through the US popularity charts for the first time since the 1880s. It's a uncommon member of the trending El- family of names, which includes Ella, Eloise, and Eleanor. 
 
Elodie derives from Elodia, the Spanish variation of Alodia, a gothic German name associated with Saint Alodia. Saint Alodia was a child martyr in 9th century Spain, along with her sister Nunilo. In France, Elodie is spelled Élodie, with an accent over the E.
 
Élodie is a mono-named Italian singer and model as well as a major character in the Emile Zola novel The Earth. Princess Elodie is the protagonist of the video game Long Live The Queen and there was a character on The Hills named Elodie.
 Popular in the UK and French-speaking countries, Elodie could make an original honor name for Aunt Melody.

Ferdinand, a traditional name in the royal families of Spain and a handsome young prince shipwrecked on Prosper's island in Shakespeare's The Tempest has, unfortunately, to the American ear a somewhat heavy and clumsy feel – most likely because of the bull connection. In the 1880's it was in the 200's on the US pop list, but has been off completely since 1986. 

 The sleeker Spanish and Portuguese version Fernando, on the other hand, is Number 253 (and 28 in Chile, 59 in Spain). An interesting Dutch spin: the short form Dinand, after a popular singer.
Portuguese explorer Ferdinand Magellan was the first European to cross the Pacific and the first person to circumnavigate the earth.

Junius is one of those names that's growing on us, along with many of its Roman countrymen such as Julius and Atticus.  We once thought it was a combination of the least attractive elements of Junior and Julius but now we think...well, we think it's okay.  Not great, but okay.

Odette is the good swan in Tchaikovsky's ballet Swan Lake, a role for which Natalie Portman won an Oscar ---and it would make a particularly soigne, sophisticated yet upbeat choice, unlike some of the more dated other 'ette'-ending names. 
 Odette de Crecy, is the flamboyant wife of Charles Swann in Proust's A la Recherche du Temps Perdu. 
 The name became publicized during World War II via the courageous French Resistance heroine Odette Brailly, who risked her life to supply information to the Allies, was captured by the Germans, and wrote her story which was retold in an eponymous film.
 Actor Mark Ruffalo chose Odette for his daughter. 
 Variant Odetta is associated with the folksinger who was one of the first to go by a single name.
 Odile, who is Odette's evil Swan Lake twin, gives her name a sinuous, sensuous appeal.

Ophelia reentered the US Top 1000 in 2015 after more than 50 years off the charts, and rose more than 600 spots since then, with no signs of slowing down. Could Ophelia may be the next Olivia?
 Ophelia is a beautiful name that has long been hampered by the stigma of Hamlet's tragic heroine—for whom Shakespeare seems to have invented the name—but more and more parents are beginning to put that association aside. There is also a gutsy Ophelia in Harriet Beecher Stowe's 1852 Uncle Tom's Cabin, which seems to have had some influence on baby namers at the time.
 
 Among the actresses who have played modern non-Shakespearean Ophelias are Jamie Lee Curtis and Blake Lively. The heroine of the film Pan's Labyrinth used the Spanish spelling, Ofelia.
 Actress Patricia Neal and author Roald Dahl named one of their now grown daughters Ophelia, and more recently musician Dave Grohl named his baby girl Ophelia Saint.

In France, pronounced PRO-spare, Prosper is a fairly common name; here it presents a worthy aspirational message for a child. 
 Prosper was the name of several early saints, including a noted fifth century theologian, St. Prosper of Aquitaine, and was a favorite of English Puritans.
 Prosper has strong associations with P.Merimee, who wrote the novel Carmen, upon which the opera is based. Prospers were also the protagonists of two other books, The Shining Company by Rosemary Sutcliff and The Thief Lord by Cornelia Funke.
 The Italian version, Prospero, is another attractive option, with ties to Shakespeare's magician character in The Tempest.

While some might assume this to be a variation on Theodore, Theodule's etymolgy actually stems from Theodulus. Though neither of these forms have attraction much attention recently, both Theodore and nickname Theo are rising up the US popularity charts. This could create an alternate path to the desirable nickname.
 Théodule Ribot was a nineteenth century French realist painter.

Viola has several positive elements going for it: the rhythm of the musical instrument, the association with the flower, the trending 'Vi' beginning and its leading role in Shakespeare's Twelfth Night. 
 In the Bard's gender-bending comedy of identity and disguise, Viola is the appealing, passionate heroine. Later takes on this tale include Shakespeare in Love, with Gwyneth Paltrow as Viola de Lesseps and She's the Man starring Amanda Bynes.
 The most distinguished current bearer is Oscar- and Emmy-winning actress Viola Davis.
 Viola was a Top 50 name from 1899 to 1911, falling off the list in 1972, but is still popular in other countries such as Italy, where it is Number 15. And with Violet not sounding quite as fresh as it did, the strong Viola could find herself back in the running.

Aglae to Zulma: Names of my Spanish-Cajun Ancestors

The most unusual names from digging way back into the history of New Iberia/New Orleans/St. Martinville. Lots of French/Spanish fusion. Most info is coming thirdhand, so any could be misspelled/inaccurate. It's often unclear which names are double-barrel and which are first/middle.
