Crisp and colorful, Autumn is the most popular season name in the US — the only one in the Top 100 in recent years — though Summer and Winter don't rank too far behind. Cool and gentle at the same time, it also ranks highly in England and Wales.

The girls have dibs on Spring, Summer, and Autumn, leaving this name evocative of snowy landscapes as the one possible seasonal choice for boys. And naturally, it's one of the most obvious names for winter babies.

Will has definitely replaced Bill, not only as a nickname for William but as a stand-alone name as well, partly thanks to England's Prince William, also known as Wills. Currently outside the Top 1000 in the US and the UK, it wouldn't feel totally out of style.

Blair with a little something extra, which some parents may feel feminizes the name. The Blaire spelling was given to a surprising number of baby girls, with about a third of baby girls with the name given this spelling. The final e also is reminiscent of Claire.

Now that Faye is back on the Top 1000 after a decades-long absence, its spelling variations are being revived as well. Fae was given to nearly as many baby girls last year as Fay and may be especially attractive as a middle name option.

Ky is a modern minimalist masculine name with multiple possible origins. As a standalone name, it may be derived from the Irish 'Caodhain' (meaning 'little battle') or can function as a shortened form of names like Kyle, Kyler, or Kyson. In Vietnamese culture, Ky can mean 'rare' or 'precious.' The name has gained modest popularity in recent decades as parents increasingly favor short, punchy names with international appeal. Its simplicity makes it versatile across cultures while its distinctive sound helps it stand out. Ky embodies contemporary naming trends that prioritize brevity and uniqueness.

Spelling variations abound when a name is trendy, which Rosalind is not these days. We say leave Roslyn back in the middle of the 20th century and reclaim the original Rosalind.

Sam as a name standing on its own was given to only 18 girls in 2021, versus over 400 boys. But as a short form it's appealing and down-to-earth for both sexes, and heard far more often: There were over 2500 baby girls named Samantha in the US in one recent year and more than 8500 boys named Samuel, so you will hear the name Sam a lot more often than you might guess judging by the numbers for this short form. Like the wildly popular Charlie, Sam is a nickname that works equally well as a girls' name as a boys'. All forms considered, Sam is still one of the most popular names that start with S.

In France, pronounced PRO-spare, Prosper is a fairly common name; here it presents a worthy aspirational message for a child.
