Caleigh (pronounced KAY-lee) twirls onto the scene with a Celtic shimmy, borrowing its rhythm from the Gaelic “céilidh,” a lively village dance, and its lilt from the modern mash-up of “Kay” and “Leigh.” She carries the Irish whisper of “slender and fair,” yet feels thoroughly all-American—think shamrocks traded for sneakers. Over the past three decades she’s waltzed around the lower half of the U.S. Top 1000—never a wallflower, but never so common that two Caleighs fight over the same cubby at preschool. Parents who choose her often say they crave a name that’s familiar enough to pronounce at first glance yet unique enough to earn its own doodle-friendly signature, and Caleigh delivers with confetti in her pockets.
