Taylor is one of the prime unisex surnames used for girls and has also been a soap opera favorite. Taylor was in the Top 10 for the last several years of the twentieth century, so that now it tends to feel a little nineties – though Taylor Swift is keeping it in the spotlight and Tay is a charming nickname. Garth Brooks and Bryan Cranston have daughters named Taylor; Taylor Schilling portrays lead Piper Chapman in Orange is the New Black.

A name that feels both spiritual and trendy, Trinity surged up the charts in the early 2000s, following the release of The Matrix. In just two years, it made an impressive jump from the latter end of the charts to the US Top 100, where it remained for more than a decade.

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.

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.

Theodosia actually appeared on the US popularity lists in the 1880s and 90s.

As Theo and Thea get more popular, so do Teo and Tea, short forms of the Latinate variations of Theodore and Matthew -- which include Dorotea and Mattea. But like Theo and Thea, Tea can stand perfectly well on its own and blends seamlessly into any Anglophone or European culture, if that is your aim. Some may argue that the Tea version is the prettiest and it's certainly the sleekest.

Doting parents have begun to use names like Precious and Treasure, which are sweet for a baby, but might not hold up over the years. Treasure was used for nearly 300 baby girls in one recent year.

Toby is an early unisex name with a Shakespearean pedigree; when used for a girl it retains its tomboyish quality. Fits well with the growing trend of boyish nicknames for girls -- alongside rising choices like Frankie and Stevie. Toby peaked as a girl's name in 1936 and was last on the charts in 1975. Though, it's been slowly rising in recent years with nearly 100 baby girls named Toby in 2023.

Tina, despite its petite and tinkly image, is apt these days to be replaced by the more elegant originals, Christina and Martina.It does have some strong namesakes, though, in Tina Turner (born Anna Mae), Tina Brown (born Christina), Tina Fey (born Elizabeth), and photographer Tina Barney (born Tina).

Though never as popular as the name of her Bewitched mother, Samantha, Tabitha has its own quirky, magical charm. The name of a charitable woman who was restored to life by Saint Peter in the Bible, it was a popular Puritan choice. Sarah Jessica Parker and Matthew Broderick chose it for one of their twin daughters, which gave it a slight boost. Nonetheless, Tabitha remains in decline.
