Evan peaked in 2007 at rank 31 and has slid steadily to 143 over the seventeen years since. The chart shape is one of the cleanest examples of a Welsh-derived name riding the broader Celtic-revival wave of the 2000s and then sliding gently as the cohort aged. Evan is now in the same chart phase as Connor and Aiden. Late-stage Celtic revival, post-peak, gently fading at a rate that suggests no comeback is imminent.
The Welsh John
Evan is the Welsh form of John, traditionally given as a derivative of Iefan (the medieval Welsh form of John, ultimately from Hebrew Yochanan, "God is gracious"). Evan as the Anglicised spelling has been in continuous Welsh use for centuries and crossed into broader English usage through the 19th and 20th centuries.
The American climb is primarily a 1980s and 2000s phenomenon, with the chart accelerating sharply during the broader Celtic-revival wave of the late 1990s. Pre-1980 SSA usage was modest. The 2007 peak coincided with the high-water mark of that wave, when Liam, Connor, Ryan, and Evan all sat in the upper half of the top 100 simultaneously.
The Welsh-name read
From a marketing read, Evan sits at a specific position in the Celtic cohort. It is unambiguously Welsh in origin, but the spelling is so phonetically clean that Anglo-American speakers do not register it as foreign in the way Cillian or Eoin would. That assimilability made Evan an easy mainstream pick during the Celtic wave but also means the Welsh heritage signal is largely invisible to most American adults today.
Sibling pairings on naming forums often place Evan alongside other Celtic-revival picks. Evan and Owen, Evan and Connor, Evan and Liam. The cohort reads as cohesive and slightly interchangeable, which is part of why the entire group is now sliding together rather than retaining individual chart positions.
The counter-reading
The honest critique on Evan is the generational coding. The name belongs phonetically to the 2000-2010 chart window, and a child named Evan in 2025 is being placed into a generation where the name reads as older sibling rather than current cohort. Parents weighing Evan today often end up considering Owen, which has held its chart position more strongly. Common pairings favour traditional middles: Evan James, Evan Cole. The 2000s data shows the cohort's peak context.
