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.

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.

Joel is one of those boys’ names that's never been super-popular yet has never been UNpopular either -- it's been in the Top 400 in the US since we started keeping statistics in 1880. So it's inevitable that its female form Joelle would gain visibility too, and indeed Joelle was used most widely during Joel's reign in the Top 100, from the late 1960s through the early 1990s.

Simona is a feminine name of Italian and Eastern European origin, serving as the feminine form of Simon, which derives from the Hebrew name Shimon, meaning 'he has heard.' This elegant name has remained consistently popular in Italy, Romania, Czech Republic, Slovakia, and other European countries. In Italy, it gained particular recognition through famous bearers like Olympic swimmer Simona Quadarella. While less common in English-speaking countries, Simona offers a sophisticated international alternative to the more familiar Simone. The name has a melodic quality with its flowing vowel sounds and soft consonants. Simona projects both strength and femininity, combining classical roots with a contemporary feel. Its cross-cultural appeal makes it accessible across various languages while maintaining its distinctive character.

Frederica is an interesting possibility for the parent unintimidated by its old-fashioned formality, and who can appreciate the vintage charm and verve lurking beneath its stuffiness.

Eugenie enjoyed a major dusting off when Fergie and Prince Andrew chose it for their daughter, restoring a patina of royal sheen it hadn't had since the time of Napoleon III's glamorous empress--who spent much of her life in England. It was also borne by Princess Victoria Eugenie of Battenberg, a granddaughter of Queen Victoria, after whom Prince Andrew's younger daughter was named.

Lucienne is a soft and ultra-sophisticated French-accented option in the Lucy family, one that could provide a fresh alternative to such fatigued Gallic choices as Danielle and Michelle.

Romantic name, feminine form of the ancient name Romanus or the modern Roman, that may rise again with the league of Rom-beginning names that also include Romy and Romilly. Romana's downside: Easy to confuse with the more familiar Ramona.

The female version of Emanuel could become more prominent, though for some it still carries a steamy image dating back to a then sensationally erotic French film. Singer and Shameless star Emmy Rossum's full name is Emmanuelle.

A sophisticated girls' name for those attracted to Leona, Leonie and Leonore.

This name is the feminization of mythological name Lysander, which is best known to English-speakers as a character in Shakespeare's comedy A Midsummer Night's Dream.

Honoring a male relative. Be bold and go with Glenn.

This pretty, international feminization of Matthew was chosen by Mira Sorvino for her daughter, Mattea Angel. As the Spanish Mateo and the Italian Matteo become more popular for baby boys throughout Europe, the English-speaking world, and the Americas, Mattea is sure to get wider recognition. And as Theo and Thea have become fashionable names, Teo and Tea are rising too.

Fashionably Continental and much fresher than Dominique, though it's been used since the Middle Ages. Dominica can be spelled any number of ways, from Dominika to Domenica, but we prefer this version.

Xaviera is one of the most intriguing and rarest female forms of a male name. Only a handful of baby girls are named Xaviera in the US each year, compared with nearly 3500 baby boys named Xavier.
