Dillon is a friendly Irish-American charmer that carries two tales in its back pocket. On one branch of the family tree it springs from the Norman-French “de Lion,” a knightly nickname for someone known for steadfast courage; on the other, it echoes the old Welsh sea-spirit “Dylan,” evoking loyalty as deep as the tides. Either way, the meaning circles back to strength and faithfulness—pretty solid qualities to pin on a brand-new human. In the States, Dillon quietly sailed along for decades before catching a wave in the late ’80s and ’90s, helped by Hollywood’s Matt Dillon and the enduring cool of Bob Dylan’s namesake spelling. While its popularity has ebb-and-flowed since then, the name still lands in the hundreds of nurseries each year, proof that parents keep returning to its easygoing, two-syllable snap: DIL-uhn. Picture a future Dillon—steady as a lighthouse, but never afraid to dive into adventure—and it’s easy to see why this classic-with-a-twist keeps finding fresh shorelines.
