Gregory is a masculine first name. It is derived from the Latin name Gregorius which was from the late Greek name Γρηγόριος (Grēgorios) meaning watchful alert (derived from Greek γρηγoρεῖν grēgorein meaning to watch).Through folk etymology the name also became associated with Latin grex (stem greg–) meaning ‘flock’ or ‘herd’.
