Gavin peaked in 2007 at rank 255 and now sits at the same number on the descending slope. The total American count of 188,131 reflects a name that climbed steadily through the 1990s and 2000s, peaked in the late 2000s, and is now in slow decline. Gavin tracked the broader 2000s wave of Welsh and Celtic-revival boy names that included Griffin and Maddox.
The Welsh white-hawk
Gavin comes from Welsh Gawain, a name that originally appeared in medieval Arthurian literature as one of King Arthur's most prominent knights. The Welsh root is genuinely contested, with scholars proposing connections to gwalch ("hawk") and gwyn ("white" or "fair") to give roughly "white hawk," or alternative readings tied to other Brythonic Celtic roots. The medieval romance Sir Gawain and the Green Knight cemented the name in English literary tradition.
The form Gavin (with V) is the modernized Anglicized spelling, while Gawain (with W) preserves the medieval orthography. Most American Gavins use the V spelling. Scotland adopted Gavin as a common boy name well before England or America, which gave the name a Scottish-tradition feel that complemented its Welsh-Arthurian roots.
The 1990s American climb
Gavin's American chart climb began in the late 1980s and accelerated through the 1990s. Musician Gavin Rossdale (lead singer of Bush, husband of Gwen Stefani) gave the name late-90s celebrity visibility, while the broader Welsh-revival cluster pulled along multiple Welsh and Celtic boy names simultaneously. The 2007 peak coincides with the broader Celtic-naming wave that also produced peaks for Aiden and Finn.
Gavin sits inside the Welsh-revival cluster with Griffin, Maddox, and Crew. The cluster has been gradually cooling since the late-2000s peak.
The counter-reading
The honest concern with Gavin in 2025 is the cohort-marking from the 2007 peak. A child named Gavin today reads as named slightly behind the trend rather than ahead of it. Some parents specifically want this kind of just-past-peak settled feel; others prefer something currently rising. The Welsh-origin cluster and falling names list place Gavin in context.
