Reese peaked in 2003 and holds rank #620 with 19,129 total SSA bearers. It's a Welsh name with a long history as a boys' surname that has spent the last two decades navigating gender — used for boys and girls with nearly equal frequency in some years. That gender neutrality is either Reese's defining feature or its main complication, depending on your perspective.
Welsh Warrior Roots
Reese is an anglicized form of the Welsh name Rhys, from the Old Welsh word meaning "ardor" or "enthusiasm" — sometimes translated as "passion" or "fierceness." Rhys was a common medieval Welsh name, borne by several Welsh princes and kings. The anglicization Reese emerged as Welsh surnames transferred into American usage. The original Welsh Rhys remains the dominant form in Wales and among families maintaining Welsh orthographic heritage; Reese is the American spelling that prioritizes pronunciation clarity.
The Gender Crossover
Reese's gender trajectory in the United States was significantly shaped by actress Reese Witherspoon, whose fame in the late 1990s and 2000s coincided exactly with the name's 2003 peak. Girls named after her or simply in her cultural wake pulled the name's gender balance. The historical Welsh Rhys was solidly masculine; the American Reese is genuinely shared. For parents choosing it for a boy today, the question is how much the gender-ambiguous association matters — and the honest answer is that some boys named Reese will navigate that ambiguity throughout school.
Still a Good Boy's Name
Rhys remains top 100 in Wales and climbing in the United States, which means the underlying name — with its sound and Celtic authority , has real legs. For boys specifically, the alternate spelling Rhys reads more clearly masculine and signals Welsh heritage more directly. Reese works as a softer, more accessible version for families without Welsh ties who simply love the sound.
