Meaning: Large settlement; Descendant of Treabhar

Trevor is a boy’s name of Welsh origin. Spelled Trefor in Welsh, Trevor means “large settlement.” It is a habitational name, meaning that it was given to people to describe the place where they lived. In Welsh, tre(f) means “homestead” or “settlement,” while fawr means “large,” in reference to people who lived in big settlements in Wales. In keeping with its Celtic heritage, Trevor is also an Anglicization of the Irish surname Ó Treabhair, which means “descendant of Treabhar.” Whichever meaning you prefer, both will pay homage to your roots and the history of the Celtic Nations.
