Kayce
The story
Kayce is a variant of Casey or Case, depending on how a family says it. Casey runs back through an Irish surname to Cathassach, which means vigilant in Irish. For decades the American record belonged to the girls: 28 in the 1950s, rising to 866 in the 1990s, with the boys' column barely awake, never more than 192 in any decade through the 2010s. Then television rewrote it. Kayce Dutton rode into Yellowstone in 2018, and the boys' line went vertical: 3,039 so far this decade, more than all its earlier boys' decades combined, many times over. The girls' figure sits at 363. A name that spent half a century leaning one way flipped in a single franchise. Vigilant, the old meaning says. The record suggests it was watching for its moment.
