Unusual and On-Trend

Sienna has been a Top 100 choice in England & Wales since 2005, the year after Sienna Miller's acting breakthrough in the hit movies Alfie and Layer Cake. In the US, it also got a big boost in the early noughties, before dropping slightly then rebounding to reach an all-time high in 2022.

Signy — also spelled Signe — would make another distinctively offbeat alternative to Sydney. Signy appears in Norse mythology as the twin sister of Sigmund.

Sleek and smart, with a hint of mystique about it, Silas is a recent addition to the US Top 100. Both mythological and Biblical in origin, Silas joins the ranks of Isaiah, Atlas, Elias, and Sebastian: polished and contemporary feeling names with plenty of history.

Simone, the elegant French feminization of Simon, strikes that all-important balance between unusual and familiar, and it's oozing with Gallic sophistication. Dwayne "The Rock" Johnson has a daughter named Simone; Chris Rock used it in the middle place for his daughter, as did Kevin Kline and Phoebe Cates

Sounds like Serena, but refers to the mythological sirens -- half woman, half bird -- who virtually sang men to death. Not a great role model for your little girl.

Skyla is the most feminine form of the Skylar / Sklyer trend - little Skyla will never be mistaken on paper for a boy.

Evoking the image of a shady glen, Slade could make a distinctive middle name. It entered the Top 1000 in 2007, and has been seen as a character name on the TV show "Smallville." It's also a name that pops up in comic books and video games.

Slater has a more genial, friendly feel than most trade names. Angela Bassett and Courtney B. Vance used it for one of their twins.

Sloane is a sleek, sophisticated surname name that has gradually morphed over to the girls' side. With its distinctive and intriguing sound, Sloane has been in the US Top 1000 since 2009, and in 2022, it made its first appearance in the UK charts, jumping more than 400 places in a single year.

Even if it is the Number one surname in the U.S.--with more than 2.5 million bearers--we still think that Smith would make a cool first or middle name, whether or not it has family history.

A bright and warm possibility for a summertime girl, Solana has been heard in a few video games. Solana Rowe is the real name of the singer known as SZA.

Solene is a variation of Solange fashionable in recent years in France and a new hit name on Nameberry.

Soraya is a Persian name made famous in the Western world by the one-time empress of Iran, who settled in Europe, primarily in France. Soraya is derived from Thurayya, the Arabic name of the Pleiades, a group of stars in the constellation Taurus.

This gentle Scandinavian name, soft and sensitive, is being discovered in a major way by parents in the US. It's most closely identified with the nineteenth century philosopher Soren Kierkegaard, but there have been modern fictional Sorens as well, in The Matrix Reloaded and the book series Guardians of Ga'Hoole, Charlie and Lola, and Underworld.

With related choices such as Lark and Phoenix gaining popularity, why not Sparrow? Though it's usually thought of as a female name, Nicole Richie and Joel Madden chose it for their son.

Spence is occasionally used as a name all on its own and it has more of a sense of completeness than many nickname-names.

Seems to stand at attention and salute.

Stellan is a strong, attractive, Scandinavian possible up-and-comer, known through actor Stellan Skarsgard, and his namesake, the son of Jennifer Connelly and Paul Bettany. Its trendy 'an' ending and the similarity in sound to the popular Kellen/Kellan make it all the more accessible.

Stephen, also spelled Steven, is a strong and likable classic, with the he's-a-great-guy short form Steve. Though not as well-used or fashionable as it was in its heyday -- it was a Top 25 name from 1946 to 1957 -- it's still a widely used name. It remains an even more popular in Ireland.

An imaginative choice with an uptempo Cory/Rory/Tori sound, perfect for the child of a writer — or anyone with a good story to tell. Story has been finding some appreciation among celebs like Minnie Driver and others as a middle name. This is just one of the literary word names that have recently entered the realm of possibility, such as Fable, Sonnet and Poem.
