Augusta is a dignified name reminiscent of wealthy great-aunts, but with the fashion for both August and Gus for boys, Augusta could get some fresh energy. 
 Augusta was the title of honor given to the wives and daughters of Roman emperors, which then morphed into a given name, brought to England by the German princess who became the mother of George III.
 Augusta is also a saint's name and a place name. Her literary Great-Aunt image was formed via the characters Lady Augusta Bracknell in Oscar Wilde's The Importance of Being Earnest, an elderly relative in the Harry Potter books, and Aunts Augusta in both Graham Greene's Travels with My Aunt and P.G Wodehouse's Jeeves and Wooster novels. 
 Augusta has a choice of two friendlier nicknames--Aggie and Gussie.

Augusta

Calla is a lily name that is much more distinctive and delicate than Lily. Rarely heard today, it did appear in the popularity lists in the last decades of the nineteenth century.
 Calla is the eponymous heroine of the Rebecca Wells novel The Crowning Glory of Calla Lily Ponder, and there's an English rock band called Her Name is Calla.
 Actress Mare Winningham named her daughter Calla way back in 1987.
Sound-alike Cala is an Arabic name meaning fortress.

Calla

Cecelia, with this spelling, got some recent attention as the name of Jim and Pam's baby on The Office -- and also the name of actress Jenna Fischer's newborn niece.  A spelling variation of Cecilia that has a gently old-fashioned feel and several appealing short forms, including Celia, Celie, and, as on the TV show, Cece.

Three times as many babies are given the Cecilia spelling as get the Cecelia one, though if you plan on calling your daughter Cece or Celia, Cecelia may feel like the more logical spelling.

Cecelia

Celia, splendidly sleek and feminine, is a name that was scattered throughout Shakespeare and other Elizabethan literature, but still manages to feel totally modern. 
 Shakespeare has been credited with introducing Celia in As You Like It, and it was to Celia that the poet Ben Jonson penned the immortal line, "Drink to me only with thine eyes." Other literary Celias have appeared in works ranging from George Eliot's Middlemarch to T. S. Eliot's The Cocktail Party to Lionel Shriver's We Need to Talk About Kevin.
 Celia Cruz was a superstar of Latin music.
 Celia is not a short form of Cecilia, which has a completely different meaning, and developed independently. But some contemporary parents are naming their babies Cecelia, especially with that spelling, and calling them Celia—which gives you two beautiful names in one.

Celia

Once a common boys' name in Ireland (e. g. , Darby O'Gill and the Little People), the dynamic Darby now has a definite unisex feel.  Actor Paul Rudd has a young daughter named Darby.

Fresh, bright, and sunny, Della could be an alternative to Ella, Delilah, or Adeline. Familiar but not yet overused, it combines the elements of contemporary favorites with vintage charm.
 
With its noble meaning and associations with delight, Della was a popular choice in the 19th century and remained so up until the 1930s, when it slowly began to fall out of favor. It disappeared from the Top 1000 in 1978, but, after an absence of 40 years, it re-entered the charts in 2018.
 
This reappearance was perhaps partly inspired by actress and singer Della Reese, who died in 2017. This could have brought the name to the attention of a new generation of parents, and it has been climbing the US charts ever since. 
 
As a diminutive of Adela or Adelaide (or perhaps Delphine, Madeline, or Idella), Della fits into the trend of nicknames as proper names, blending well with the likes of Mila, Josie, and Nora.
 
As of 2023, it is given to around 450 girls in the US each year and may well be one to watch out for. A small caution, however, is that della does mean "from the" in Italian.

Della

Edie is part of the Evie-Ellie et al family of cute and friendly short forms that sometimes stand on its own. Briefly popular in the 1960s, it could well be due for rediscovery. It's already a fashionable choice in the UK, where it has ranked just outside the Top 100 for several years.

 Several Ediths have chosen to be known by this pet form, including socialite and Andy Warhol superstar Edie Sedgwick, actress Edie Falco, singer Edie Brickell and the Jacqueline Bouvier Kennedy relatives called Big and Little Edie in the iconic documentary Grey Gardens. Edie Britt was the character portrayed by Nicolette Sheridan in Desperate Housewives.

 British actress Samantha Morton chose Edie for her daughter as did Keira Knightley in 2015. We think Edie is going to continue to rise in the coming years.

Edie

Fifer is a musical name that fits in seamlessly with the likes of Harper and Piper, but is much more unusual. It's also a Scottish demonym, referring to an inhabitant of the historic Scottish county of Fife.

Fifer

Georgia is so rich, lush and luscious, it's almost irresistible. Georgia's now a rising star among the feminizations of George, helped by associations with the southern state (named for British King George II) and painter Georgia O'Keeffe, with the Ray Charles song "Georgia On My Mind" or maybe "Sweet Georgia Brown" playing in the background. 

 Georgia is in fact a double place name, also belonging to an ex-Soviet state famous for the ancient monastery Vardzia and its rich culinary and wine-growing culture.

 Georgia has been chosen for their daughters by Harry Connick, Jr., Hope Davis, Amy Ryan, Zac Brown, Rebecca Gayheart and Eric Dane, and Felicity Huffman and William H. Macy.

In the USA, Hattie is one of those nicknames that is now more popular than its parent name, Harriet. In England, however, Harriet is still by far more popular than Hattie, while in Australia, Harriet is highly popular while no data exists on Hattie. In the US, we’d like to see Harriet get more usage but we’re happy to see Hattie again.
 Hattie was popular at the end of the nineteenth century, in the Top 50 from 1880 to 1900, along with other similar nickname names like Lottie and Letty. It fell off the list in 1969, to return in 2011, the year of Hattie McDermott's birth.
 Hattie McDaniel was the first African-American to be awarded an Academy Award, in 1940, for her role in Gone With the Wind. Hattie was the name of the sweet, simple protagonist in Woody Allen's 1999 film Sweet and Lowdown; Hattie (born Henriette) Carnegie was a well-known twentieth century fashion designer.

Hattie

Josephine, with its large measure of class and character and a gently offbeat quality, has been on a gentle uphill climb in the US for over 30 years, now ranking in the Top 100. With an intriguing number of vivacious nicknames, from Jo to Josie to Fifi to Posy, Josephine is a Nameberry favorite.
 
Josephine is the feminine form of Joseph, a name ultimately derived from the Hebrew Yosef, meaning "Jehovah increases." In French it has an accent over the first E, which was omitted in the English, German, and Dutch translations of the name. Empress Joséphine du Beauharnais was born Marie-Josephe-Rose, but called Josephine by her husband, Napolean Bonaparte.
 
Josephine Baker (born Freda), the American-French singer, dancer, and civil rights activist, is a potential namesake.
 Some of the Josephines in literature and recent pop culture are known by their nicknames—the admirably headstrong Jo in Little Women, Joey Potter (played by Katie Holmes) in Dawson's Creek, and Josie of Josie and the Pussycats. In Some Like it Hot, Josephine was the nom de femme of Tony Curtis.
 Josephines have been the subjects of countless songs, performed by artists ranging from Fats Domino to Tori Amos to the Black Crowes.

Josephine

A cute nickname, but June is a much better bet for the birth certificate.

Junie

Lettie, also spelled Letty, is a nickname name not heard in over a century, giving it the patina of a treasured antique. Lettie's style currency is rising with the trend for old-fashioned, down-to-earth nicknames. Lettie is right in step with Lottie, Hettie, Hattie, Josie, and Maisie.
 One of Joan Crawford's early hit roles was in 1932 as the eponymous heroine of the film Letty Lynton, in which she wore a dress--dubbed the Letty Lynton dress--that became a national fad.

Lindy

Mae, a sweet and springlike old-fashioned name, hadn't been on the national charts in forty years, but finally made it back in 2010. Mae is derived from May, the month name that was chosen for its connection to Maia, the Roman goddess of growth and motherhood. 
 
Mae can be used as a nickname for the names Mary and Margaret — actress Mae West was born Mary. Alternate spellings include May, Mei, and Maye. The May spelling makes it more of a month name, while Mae makes it an antique nickname name. Both can stand on their own, as seen by Hilary Duff's choice of Mae as her daughter's first name.
 Mae along with twin sister May is now one of the prettiest and most popular middle name options for girls (Eric Clapton has an Ella Mae, Greg Kinnear an Audrey Mae, Ian Ziering a Penna Mae). 
 
A Top 100 name through 1920, Mae was big in early film history — there were leading actresses named Mae Clarke, Mae Marsh, Mae Busch, and Mae Murray. Towering over them (figuratively) was Mae West, who changed the name from sweet to sophisticated. Madonna also played a character called Mae in the 1992 movie A League of Their Own.
 
Mae Jemison was the first African-American woman to travel in space. Mae Whitman is a rising young actress seen recently on Parenthood and Arrested Development.
 
It may be worth noting that Mãe is the Portuguese word for mother, so if you've got Brazilian or Portuguese relatives, it's probably best to stick to May or Mei.

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

Retro short form of Marina, now dated to the era of the Hitchcock movie that made it famous. In the UK, it's one of the hottest vintage names of the moment, perhaps inspired by British singer Lily Allen, who gave it to her second daughter in 2013. It's also a character name on the hit TV show Girls.

Marnie

Nola, a name with a sleek, enigmatic quality, was used for the much-pursued heroine of Spike Lee's 1986 breakout film, She's Gotta Have It, and again by Woody Allen in Match Point. It's a short form of the traditional Irish name Fionnuala. Nola reentered the US Top 1000 in 2008, for the first time in 50 years.
 
Nola is also a place name of an Italian town, associated by ecclesiastical tradition with the invention of church bells, leading some to give that as the meaning of the name. 
 Speaking of the map, Nola could also come from New Orleans, Louisiana, for which NOLA is a frequent acronym. This association lends the name a potentially Southern feel.

Nola

Pearlie

Austrian actress Romy Schneider seemed to be the singular bearer of this international nickname name until it found new style currency in the past decade. 
 Like other Ro-names Roman, Rowan, and Romeo, Romy has gained favor with the celebrity set. Matt Lauer has a daughter named Romy, as do director Sofia Coppola and Phoenix frontman Thomas Mars and others. British Prime Minister Boris Johnson and wife Carrie named their daughter Romy in 2021.
 Some might remember the 1997 comedy Romy and Michelle's High School Reunion, with Mira Sorvino as Romy.
 Romy hasn't entered the US Top 1000 as yet, but it's a Top 100 name in several European countries, and especially popular in France. In Spanish-speaking countries, Romy is also a diminutive of Romina, and was very popular in the eighties and early nineties.

Romy

Rosalie hit its apex in 1938 and then slid straight downhill until it fell off the U.S. Top 1000 completely in the 1980s, only to spring back to life in 2009 as the name of a character in the Twilight series. The beautiful vampire Rosalie Hale has breathed fresh life back into this mid-century name, and the fact that the character is both sympathetic and relatively minor means Rosalie has the chance to thrive again as a baby name without feeling unduly tied to Twilight.
 For a long time Rosalie's main claim to fame was via the eponymous 1928 Broadway musical, which became a movie ten years later, both of which included a hit song.
 Rosalie was used as a character name in literature by Anne Bronte and Oscar Wilde. In the mid-twentieth century, Rosalie was the name of the daughter on The Goldbergs. More recently, Rosalie is a character on Grimm.

Rosalie

The name is derived from the term commonly used in the Book of Psalms, which has a many Hebrew scholars in confusion over its meaning. Given its context in the Bible, Selah is likely to mean "to praise" or "pause and reflect upon what has just been said." Lauryn Hill used this name for her daughter. It is the last word in Anita Diamant's novel The Red Tent.

Selah

Tilly and twin Tillie are hot new nickname names, either short for the newly fashionable Matilda or standing all on their own.

Tilly

Willa has become increasingly fashionable, with its combination of Willa (born Wilella) Cather-like pioneer strength and the graceful beauty of the willow tree. 
Sophie Turner and Joe Jonas are the latest celebrities to welcome a daughter named Willa. Other stars who used this name include actress Keri Russell, who named her daughter Willa Lou and the late actor Philip Seymour Hoffman, who used Willa for the youngest of his three children. David Mamet and Brian De Palma also have daughters named Willa, plus it's the middle name of Meryl Streep's actress daughter Mary (called Mamie.) Young Willa characters have appears on Six Feet Under and True Blood.
 Willa originated as a short form of Wilhelmina. After a half-century hiatus, it reentered the U.S. Top 1000 in 2010 and soared to the Top 500, for the first time since 1949, in 2015. Willa might also work as an honor name for an ancestral William.

Willa

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.
 Winnie had been used regularly on its own in the U.S. through the early 1950's and has a number of varied namesakes. There's the Pooh, of course, and also Winnie Mandela, former wife of South African President Nelson; Winnie Cooper, the charming girlfriend of the young hero on The Wonder Years--whose given name was Gwendolyn; Winifred "Winnie" Foster, a main character in the childhood classic Tuck Everlasting; and it was also a nickname for Winston Churchill.
