Baby Names Going Extinct: Charleigh, Kylian, and More Decline

BabyCenter's annual report on baby names at risk of “going extinct” highlights steep declines for place names like London and Dallas, as well as boy names ending in -y such as Grady and Corey. The data, based on the top 1,000 names submitted by users who had babies in 2025, shows the sharpest year-over-year drops.

Surprising Declines in -y Ending Names

“I didn’t expect to see boy names that end in -y drop so much in popularity — especially a name like Harry, which has that nickname-as-a-full name charm that’s popular right now,” said Rebekah Wahlberg, a baby name trends specialist at BabyCenter. Huxley and Rey also made the list.

Unique Spellings Fall Out of Favor

Nontraditional spellings like Charleigh, Kori, Everlee, Alivia, Maddison, and Emmitt are declining. “It doesn’t surprise me that unique spellings are falling out of style,” Wahlberg said. “They’ve been the target of a lot of online commentary lately — plus, having a uniquely spelled name can come with complications. Parents today are thinking about that when deciding how to spell their babies’ names.”

Names Starting with D and K Decline

The report also notes a fall in names beginning with D and K, including Danielle, Dylan, Kenna, and Kinley for girls, and Dominic, Dev, Kylian, and Karim for boys. Kylian dropped 512 spots, the steepest decline among boys.

Timeless Names Endure

Despite these declines, many names remain popular. “The longevity of some of these names at the top is really neat to see,” Wahlberg said. “Take Sophia, for example — it was our number one name for more than a decade, and is still in the top three today.” Other timeless picks include William, Emma, Noah, Matthew, Luke, Isabella, Benjamin, and Jack. “It doesn’t surprise me that many of our timeless names are rooted in ancient cultures or biblical texts,” Wahlberg added. “Parents are drawn to these names’ rich history and deep meanings. It’s also common to carry on family traditions through names.”
