Kayce peaked in 2024 at rank 419 with just 2,468 total American boys carrying the name, the smallest cumulative count in this rank tier. The numbers tell a clean story: this is essentially a brand-new entry to the SSA charts, climbing rapidly on the back of a single pop-cultural anchor rather than any historical or etymological foundation.
The Yellowstone effect
Kayce is an American English respelling of Casey, with the K- onset and -ce ending giving it a more visually distinctive shape. The character Kayce Dutton on the Paramount Network series Yellowstone (2018 onward), played by Luke Grimes, drove almost the entire SSA appearance of this spelling. Before Yellowstone's premiere, the name barely registered in birth records.
The traditional Casey comes from Irish O'Cathasaigh, meaning "descendant of Cathasach" ("vigilant" or "watchful"). The Kayce respelling drops that etymological lineage in favor of a cleaner brand association. This is one of the clearest contemporary examples of a TV-driven naming spike, comparable to Khaleesi from Game of Thrones or Renesmee from Twilight.
The Western register
Kayce fits the contemporary Western and ranch-aesthetic naming register alongside Wyatt, Colt, and Ridge. Browse rising names for the broader cohort context. The KAY-see pronunciation stays clean, though spelling clarification will be a lifetime task for the bearer.
The counter-reading
The practical consideration with Kayce is the show-name shelf life: names tied to a single TV character age in lockstep with the show's cultural relevance, and Yellowstone's run will end at some point. The respelling locks the name into 2020s identification, and bearers will spend their lives explaining why it isn't Casey. Parents comfortable with that tradeoff get a name with a clear contemporary hook, while parents looking for longer-term durability may want to consider the traditional Casey spelling.
