What Trevor means
Trevor means big settlement, or large homestead. The Welsh joins tref, a settlement or farm, to mawr, big, so the name describes a place by its size.
Where Trevor comes from
Trevor is the Welsh Trefor — tref, a settlement, farm or town, joined to mawr, great or large. The tref element is one of the most productive in Welsh and Cornish place naming, and the old rhyme about Cornish surnames — by Tre, Pol and Pen shall ye know Cornishmen — turns on it. Trevor became a surname of a powerful Welsh family and then a given name, and its twentieth-century use is largely English and American rather than Welsh, which is the usual fate of Welsh surnames that cross over.
