Trevor
Meaning
from a Welsh place name meaning 'large settlement'
The story
Trevor came from a Welsh surname, which in turn came from Welsh towns meaning big village. The older elements are Middle Welsh tref, village, and maur, large. Trefor preserves a more visibly Welsh spelling, while Trevor became established in English. As a given name it grew in Britain around the middle of the twentieth century and caught on in the United States afterward. The US curve rises gradually from the 1960s, accelerates through the 1980s and 1990s, reaches its clear high point in the 2000s, then retreats in the 2010s and 2020s. That shape makes Trevor a strong late-twentieth-century marker in America, even though the place-name underneath it is far older. It is a surname name with an actual landscape behind it, not an invented modern sound.
