Meaning & origin
Trevor is a Welsh-derived name that has been in consistent use in the United States since at least 1915, when it first appeared in Social Security records. It reached its peak popularity in 1998, ranking among the top 200 names at that time. The name has a falling trajectory since 1998, but remains familiar. In 2025, it ranked 679th, with an incidence of 1 in 4,270 births, down from its peak. The name was most popular in states like New Hampshire, Mississippi, and Connecticut during its peak decade. Trevor's long history and straightforward pronunciation give it a steady, classic appeal.
Trevor derives from the Welsh place name Trefor, composed of tref 'homestead, settlement' and mawr 'large, big'. It originally referred to someone from a place named Trefor, such as the village in Denbighshire, Wales. The name was brought into English usage and has been used as a given name since the 19th century, particularly in Wales and Cornish-speaking areas.
