Collier

If you're looking for a boy's name that's tough and resilient, Collier's got a strength that's undeniable! This British pick has been around since the mid-1600s and was originally used as an occupational name for a "coal miner." Although the coal days are largely over, Collier still shines bright like a diamond in the rough! Some other choices with this energetic meaning include Cole, Colston, and the more gender-neutral Colby.
