Christian name

Traditionally, a christian name or baptismal name is a personal name given on the occasion of Christian baptism, with the ubiquity of infant baptism in medieval Christendom. In Elizabethan England, as suggested by Camden, the term christian name was not necessarily related to baptism, used merely in the sense of "given name":

"Christian names were imposed for the distinction of persons, surnames for the difference of families."

A christian is an adherent of Christianity.
