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.

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.

Seraphina is one of the most-searched name on Nameberry, destined for even greater popularity. The highest-ranking angels, the six-winged seraphim, inspired the lovely name Seraphina.

Stella is a name with star quality and sparkle, that manages to sound both ethereal and earthy. Celestial but not otherworldly, it lands somewhere between the popular Ella and bold Seraphina.

Although Sylvia seems to be having somewhat of a revival among trendsetting baby namers, we'd still opt for the even gentler and more unusual Sylvie. Despite being dated in its native France (where it was popular during the 1950s and 60s), in English-speaking regions it still feels fresh and international without being unfamiliar and has a cosmopolitan, international air. It debuted on the US Top 1000 in 2016.

Sophia, which was the Number 1 girls' name in the US from 2011 to 2013, is among the top girl names in the Western World, with a sensuous sound and high-minded meaning. A real winner, Sophia reached the top of the charts without losing any—okay, much—of its sophisticated beauty.

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.

Spencer is a name that has everything: it's both distinguished sounding and accessible, dignified but Spencer Tracy-like friendly. Picked by several celebrities (a couple of times even for a girl), adding up to an enthusiastically recommended choice.

Sofia is a refined variation of the Greek name Sophia, which was derived directly from sophia, the Greek word for wisdom. It was the name of a Roman saint—the mother of Faith, Hope, and Charity—and queens of Russia and Spain.

The musical, sylvan Sylvia seems poised to join former friends Frances and Beatrice and Dorothy back in the nursery.

A place name with a deep Southern accent, the once-obscure Savannah shot to fame, with others of its genre, on the heels of the best seller Midnight in the Garden of Good and Evil, which was set in the mossy Georgia city of Savannah. Originally a substitute for the overused Samantha, Savannah is now popular itself, long among the top girls' names starting with S.

The temperature is definitely rising for this popular seasonal name, which began being used in the seventies, and has been heard consistently ever since.

Siobhan is the Irish variation of Joan, which is derived from the ancient Anglo-Norman name Jehanne. In this way Siobhan is indirectly related to the name Sinead—the Irish form of Jeannette, which also derived from Jehanne—although Sinead is not a nickname for Siobhan. Siobhan was the name of several early Irish queens and was introduced to the American public by the actress Siobhan McKenna.

With the prevailing popularity of Samuel, some parents are considering this more (literally) powerful biblical name, which shares the desirable nickname of Sam.

Sean, after a long reign as one of the top Irish boys' names in the US, has now slipped as parents look to fresher Irish choices such as Liam and Aidan. In Ireland, Sean is still highly popular, but variation Senan, an Anglicized spelling of diminutive Seanan, is also stylish in Ireland. While Sean is the Irish form of John, Seanan and Senan may be thought of either as Sean diminutives or relatives of the Latin word "senator".

Sally is a cheerful, fresh-faced girl-next-door name that was originally a nickname for Sarah, but has long been used independently. Sally was popular in the eighteenth century and then again from the 1920s to the 1960s--it was just outside the Top 50 around 1940. Though it hasn't been heard as a baby name for decades, we can see Sally bouncing back, especially after her exposure as young Ms. Draper on Mad Men--the Nameberries rank it at Number 621, and it's a Top 100 name in Sweden.

Skylar is a name with a hint of both edginess and whimsy and it makes for a nature-inspired choice that is neither too wordy nor too floral. Popular since the 90s, Skylar has remained in the US Top 100 for over a decade and is the most popular spelling of the name for girls.

A cool, windswept, surfer babe-magnet in 1965, a nice dad -- or even granddad -- today.

Seren is a top girls' name in Wales – and a lovely choice almost unknown elsewhere. Seren, in the Sirona form, was an ancient goddess of the hot springs.

Popular throughout Northern and Eastern Europe, particularly in countries like Sweden, Norway, Russia, and Germany, Sonja has a rich cultural heritage. The name gained international recognition through figures like Sonja Henie, the Norwegian Olympic figure skating champion.
