Cosima, the kind of elegant and unusual name the British upper classes love to use for their daughters, is given to a handful of baby girls in the US after being chosen by two high-profile celebs in the same month; cool couple Sofia Coppola and Thomas Mars as well as supermodel Claudia Schiffer. It was used earlier by celebrity chef Nigella Lawson, while the male form, Cosimo, was given to the son of Marissa Ribisi and Beck.

Wilhelmina might once have been condemned as a clunky relic best left in the past, but a steadily increasing number of parents are dusting it off for their 21st century babies. A reasonably popular choice in the 19th century, but out of favor by the 1950s, in the last decade, Wilhelmina has attracted more attention, and was given to around 110 babies in a recent year.

Octavia began as the Latin, then Victorian name for an eighth child. While there aren't many eighth children anymore, this ancient Roman name has real possibilities as a substitute for the overused Olivia; recommended for its combination of classical and musical overtones. It was chosen for his daughter by Kevin Sorbo.

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.

Philippa is a prime example of a boy's name adapted for girls that was common as crumpets in Cornwall, but rarely heard stateside. That was before the advent of royal sister-in-law Philippa Middleton, who goes by the lively nickname Pippa.

Augusta is a dignified name reminiscent of wealthy great-aunts and stately homes, but with the fashion for both August and Gus for boys, and the renewed interest in clunky classics like Gwendolyn and Winifred for girls, Augusta might just appeal to contemporary parents.

Widely used across Europe as a common baptismal name symbolizing spiritual rebirth, Renata, in this country it has an operatic image via Italian-born divas Renata Tebadi and Renata Scotti.

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.

A Scottish favorite that could make it here thanks to its similarity to the word divine. It's the most popular of several feminizations of David used in Scotland, including Davida, Davinia and Davidina, which have less of a chance in the U.S. It reentered the US Top 1000 for the first time in two decades in 2016.

This name of a third-century Christian martyr has an romantic, appealing feel in the modern world. It first came to American attention via Prince's love interest in the film Purple Rain. It could make an unexpected route to sweet nickname Polly — or perhaps to the quirky apple!

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.

Ambrosia combines some of the more whimsical qualities of more popular Aurora and Isabella, with a heavenly meaning.

Classic Wilhelmina is still the dominant form of this name, but the more intuitive, streamlined Willamina is rising alongside it. The phonetic spelling eliminates some of Wilhelmina's bulk, taking it from geek-chic to modern feminissima.

While Charlotte and Caroline are considered stylish and classic members of the Charles family, this Germanic form peaked in the US at Number 76 in 1965. It fell out of favor in the 2010s, but recent years have seen it re-enter the Top 1000.

Roberta has been one of the most successful feminization names, up at #64 in 1936. It's a name that's found all over children's lit, often nicknamed Bobbie or Robbie, though Bertie is another possibility. Notable bearers have included singers Roberta Flack and Roberta Peters--plus it's the birth name of Joni Mitchell.

Possibility for a dark-haired babe.

Ever since the enormous German cannon was dubbed by Allied soldiers "Big Bertha" in World War I, this name hasn't worked for a sweet little baby girl. But this was not always so. Hard as it might be to imagine now, Bertha was a Top 100 name until the 1930s, and in the 1880s was the seventh most popular name in the land--the equal of Joseph.

Amadea is a strong and musical feminine form of Amadeus, as in Mozart.

A name with several distinguished namesakes: the wife of ancient Roman Emperor Marcus Aurelius, a famous Italian opera singer, and two Catholic saints--making it both substantial and unusual.

Edwina may still be taking tea in the parlor, but we can see her joining friends like Matilda and Josephine for a comeback, especially if pronounced like Edwin rather than Edween.
