Its source is calvus, a Latin name meaning "Bald."
This boy's name is used in Spanish.
The use of the modern form of this name began in honor of the Protestant theologian known in the English-speaking world as John Calvin (1509-64). In fact, the French-born reformer was known to his own people as Jean Chauvin. (This surname was the same as that of a later French figure whose extreme zeal for his country gave rise to the term ''chauvinism.'')
The French surname, if not ultimately derived from the Latin ''calvus,'' had the same meaning, and when the name was translated into other languages the Latin term was used as a point of reference.
