Trevor is a Welsh transplant derived from Trefor, a compound of tref “homestead” and mawr “large,” literally evoking the image of a sizeable, self-reliant village. Spoken simply as TREV-er, the name reached the United States in earnest after World War II, then rose methodically until it slipped into the national Top 100 around the turn of the millennium. Its popularity has eased since, now hovering in the mid-500s—respectable, but no longer elbow-to-elbow on every playground. The cultural résumé is suitably varied: broadcaster Sir Trevor McDonald lent it journalistic gravitas, comedian Trevor Noah exports it nightly from New York, and more than one fictional knight has cantered through Arthurian retellings wearing the same badge. With crisp consonants, Celtic pedigree and a track record of steady if unspectacular use, Trevor offers parents a familiar yet uncluttered option—more village green than crowded market square.
