You might think Artemisia is the feminine form of the name, but in fact the original Artemis is feminine too, the name of the Greek mythological goddess of the moon.  Artemisia Gentileschi was an esteemed Italian Baroque painter, unusual in an era when not many women were acknowledged.  Artemisia is also a genus of plants which include sagebrush and tarragon.

Artemisia

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

Variant of Brunhild, still clad in heavy armor. Though the heroine Brunhilda of Quentin Tarantino's recent film Django Unchained may have given this version of the name new appeal.

Brunhilda

Eugenia, a name scarcely used at all since the 1980's, is another that flourished a century ago and could be due for a revival.
 Eugenia has some interesting literary references, including the fascinating Baroness Eugenie Munster in Henry James's The Europeans and Eugenia Alabaster, a leading character in A. S. Byatt's Angels and Insects, and it was also the birth name of Skeeter in the book and film The Help.
 The third century St. Eugenia, an early Roman Christian martyr, is remembered for disguising herself as a man to escape persecution.
 Music lovers will be familiar with the name of renowned flute virtuoso Eugenia Zukerman.

Eugenia

Ancient martyr's name that, though not especially appealing, might still be mildly possible, especially for Anglophiles. It was widely used in early Scotland, but was overtaken by its nickname, Effie.

Euphemia

Etheldreda 

This yellow harbinger spring bloom was named for Scottish botanist William Forsyth, and is even more unusual than such species as Acacia and Azalea.

Forsythia

Frederica is an interesting possibility for the parent unintimidated by its old-fashioned formality, and who can appreciate the
vintage charm and verve lurking inside its stuffiness. 
 The name emerged in eighteenth century Prussia when supporters of King Frederick the Great began to name their daughters in his honor, and is currently reporesented by opera star Frederica von Stade.
 Nicknames include the obvious Freddie, plus Rica and Fritzi.

Frederica

Though twin brother Gerald is still in baby name limbo, Geraldine is in line to follow the path of Josephine to imminent revival—even though Gerry is not as spunky a nickname as Josie.
 Geraldine was at its hottest from the 1910s through the forties, peaking at Number 38 in 1931. It was invented in the time of Henry VIII by a noble poet who fell in love with a Lady Elizabeth Fitzgerald and, taking off from her surname, referred to her as the "Faire Geraldine."
 Geraldine has the distinction of being the name of the first woman to be a major party vice presidential candidate, Geraldine Ferraro. Other notable bearers include actors Fitzgerald, Chaplin, and Page, and Spice Girl Geri Halliwell.
 Trivia notes: Geraldine is the middle name of Ramona Quimby. And Geraldine was the name of the sassy female character played by Flip Wilson on his popular TV variety show.

Geraldine

Despite a return to such feminizations of male names as Josephine, Clementine, and Theodora, starchy Henrietta has not made it into that group. Still, if you look hard enough, you'll see that Henrietta has the same vintage charm. 
 The name arrived in England in 1625 via King Charles I's wife, the French princess Henriette Marie, who became known as Henrietta Maria. Her daughter shared her name but was known as Minette.
 It has been prominent recently through the bestselling book The Immortal Life of Henrietta Lacks, the story of the poor black woman whose cells became one of the most important tools in medical research. Henrietta Szold was a U.S. Zionist leader and founder of the Hadassah Women's Organization. 
 Henrietta has a number of charming vintage nicknames, including Etta, Hetty and Hattie.

Henrietta

Saint's name made infamous by Philippine dictator's wife Imelda Marcos. A more positive famous bearer is the British actress Imelda Staunton, best known for playing Dolores Umbridge in the Harry Potter movies.

Imelda

In mythology, Iphigenia was sacrificed by her father, Agamemnon -- a difficult legacy to pass on to a daughter, and only one reason the name is hardly ever used. 

Iphigenia

Leopoldina 

Philomena is an earthy Greek name now used in various Latin countries. While it has felt simply clunky for many years, it's starting -- along with such sister names as Wilhelmina and Frederica -- to sound so clunky it's cool.

 Also a saint's name--that of a thirteen-year-old martyr of early Rome--it's commonly seen in Italy and Spain spelled Filomena. Philomena only started appearing in English-speaking countries in the latter half of the nineteenth century, especially in Scotland and Australia.
 In the US, Philomena ranked in the Top 1000 through 1940, peaking at Number 355 in 1915.
 Philomena Guinea is the name of protagonist Esther Greenwood's patron in Sylvia Plath's The Bell Jar. New attention was brought to the name via the Oscar-nominated eponymous film based on the real-life Philomena Lee.

Philomena

A name some people first encountered in the old children's book series The Five Little Peppers, in which Sophronia, the youngest of the Peppers is nicknamed Phronsie.`It was also used by Dickens in two of his novels: The Old Curiosity Shop and Our Mutual Friend.
 An archaic option for elaborating on Sophie/Sophia.

Sophronia

Theodora is one of the most revival-worthy of the charmingly old-fashioned Victorian valentine names, softly evocative but still substantial, as is the reversed-syllable Dorothea. 
 
The name Theodora was borne by several saints and by the beautiful ninth wife of the Emperor Justinian, who became the power behind his throne. A later royal was Princess Theodora of Greece and Denmark, the older sister of the late Prince Philip, Duke of Edinburgh. 

 Keith Richards named his daughter Theodora (with whom he recently collaborated on a best-selling children's book) in 1985; Robbie Williams did the same just last year. In TV's Grey's Anatomy Dr. Theodora "Teddy" Altman was a surgeon.

 Theodora offers a menu of neat nicknames, from the classic Teddy to trendy Thea to the vintage Dora. Theodora also has some cool international variations as well: Theodosia, Feodora and Teodora. It reentered the US Top 1000 in 2019 for the first time in over 60 years and seems destined to follow brother name Theodore toward the top of the list.

Theodora

This feminine form of Theodosius has long been buried deep in the attic, but might be a good discovery for the parent who wants to move beyond Theodora. Vice President Aaron Burr named a daughter Theodosia ("Dear Theodosia" is a song in the smash musical Hamilton), and it was the birth name of silent screen vamp Theda Bara. Theodosia actually appeared on the US popularity lists in the 1880s and 90s.

Theodosia

Though rarely used now that many parents would rather appropriate men's names than sweeten them with feminine endings, Thomasina does have some vintage appeal. 
 Thomasina Coverly plays a large part in the Tom Stoppard play Arcadia. And Thomasina also has some critter cred--Thomasina Tittlemouse is a Beatirx Potter character, there's a Disney movie called The Three lives of Thomasina, about an enchanted cat, and a Paul Gallico novel titled Thomasina, the Cat Who Thought She was God.
 Another version is Thomasin, newly visible via the 2016 horror movie The Witch and also used for a major character in Thomas Hardy's novel The Return of the Native. Hardy's heroine is commonly called Tamsin, the more popular short form.

Thomasina

Wilhelmina was long burdened with the Old Dutch cleanser image of thick blond braids and clunky wooden clogs, but that started to be changed somewhat by the dynamic Vanessa Williams character on Ugly Betty, and even further by the choice of Wilhelmina by ace baby namers Natalie and Taylor Hanson. For the less adventurous, Willa is, for now, still a more user-friendly female equivalent of William.
 Wilhelmina was a lot more commonly heard in the U.S. at one time: it was as high as Number 215 in the 1880s, but has been off the list completely since 1955.
 Queen Wilhelmina reigned in the Netherlands for most of the early twentieth century, becoming a heroic figure during the two World Wars. The name got an infusion of glamour via Wilhelmina Cooper, the Dutch-born model who established the top Wilhelmina Model Agency in 1967. Wilhelmina "Willie" Scott was the name of the Kate Capshaw character in Indiana Jones and the Temple of Doom.
 To enliven her image, Wilhelmina has a plethora of nicknames: Mina, Minna, Minnie, Minka, Billie, and Willa.

Wilhelmina

One of the few remaining unrestored vintage gems, with a choice of two winning nicknames--the girlish Winnie and the tomboyish Freddie. Winifred, the name of a legendary Welsh saint, was a Top 200 name into the mid-1920's.
 Winifred was one of the Forsytes in The Forsyte Saga, Winifred Foster was the heroine of Tuck Everlasting, and another appeared in Joss Wheden's Angel; in Once Upon a Mattress, Princess Winnifred (two n's) sings the song 'A Girl Named Fred'. The Disney folks seem to have been fond of the name--they used it in Jungle Book, Mary Poppins and Hocus Pocus. 
 Actress Jacqueline Bisset was born a Winifred and notable Winnies include Mrs. Mandela and the young girlfriend on The Wonder Years. Formerly considered old and fusty, Winifred is back in, featured amongst the newest additions to the US Top 1000 in 2023.

Winifred

Zephyr may not be a name often heard in the U.S., but its variations are used throughout Europe. Zephyrine, a cousin in sound and feel if not in fact to such lovely names as Severine and Seraphina, has distinctive possibilities.
