My favorite names.

Sapphire goes waaaaay beyond Ruby and Pearl. This September birthstone, occasionally used a century ago, might be worth a reappraisal, perhaps as a Sophie/Sophia alternative. Sapphire is the pseudonym of Romona Lofton, who wrote the book Push, which was turned into the movie Precious. Sapphire entered the Top 1000 for the first time in 2022, and is proving to be one of the freshest gem names for girls. Another intriguing variation is the lovely Sapphira.

Scarlett Johansson is doing more for this sparky southern name than Scarlett O'Hara ever did. Since the turn of the 21st century, Scarlett has gone from an obscure literary name to one of the most popular girls' names starting with S, right after longtime favorites Sophia and Sofia.

Sebastian is an ancient martyr's name turned literary, and Little Mermaid hero—think Sebastian the Crab—that's more popular than ever, as a classic-yet-unconventional compatriot for fellow British favorites T Theodore and Oliver.

Mysterious.

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.

Sierra is a name borrowed from the western mountain range, with Latin rhythm and cowboy charm, that has led to many offshoots: Cierra, Cyara, and so on. It is now probably past its peak but retains its pretty-yet-strong sound. The meaning refers to the sharp, irregular peaks of some of the Western mountains such as the Sierra Nevada.

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.

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.

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.

Yes, Spencer makes a plausible and powerful female choice these days, though still thought of as primarily for boys. Kelsey Grammer used it for his daughter in the 1980's. Spencer made its first appearance on the girls' Top 1000 in 2017.

Spiritual word names are becoming more and more popular – think Peace, Bodhi, Zen and Psalm – and Spirit is among the rarer options, given to a couple dozen baby girls each year in the US. It's the name of the horse in the kids' TV show Spirit.

Tatum is strong, distinctive, energetic, and recommended, especially if your last name is as congenial as O'Neal. The name is now used for both genders, with the balance running about two to one in favor of the girls.

Not too long ago, Temperance was found only on lists of Puritan baby names.

How do you spell Teresa? Teresa, the simpler phonetic form of this name, was the most popular variation for its early life, when it was used exclusively in Spain and Portugal. Other spellings of Teresa include Theresa, the usual English form, and the French Therese.

One of the first luxury brand names and the quintessential Booming Eighties status-conscious moniker; used by Donald Trump for his daughter, Tiffany has plummeted far from its high in the Top 25.

Tobias is one of a number of s-ending boys' names that are riding a wave of popularity. With its Old Testament-Dickensian feel, it's a name with a distinguished pedigree.

Troy shot to popularity as a first name in tandem with that of 1960s heartthrob Troy (born Merle) Donahue; its image has now, thanks in part to the Brad Pitt-starring epic, Troy, receded back to conjuring up the ancient site of the Trojan wars.

A creative spelling of Uriah, possibly without the negative connotation. Biblically, Urijah was a prophet mentioned in the book of Jeremiah.

Valentine is an attractive Shakespearean name with romantic associations, but those very ties to the saint and the sentimental holiday have sent it into a decline, one which we think may be about to turn around.
