Creg is an unusual and distinctive name of Irish origin. It is derived from the ancient Irish name Críogán, which means "little spear." While it was once quite common in Ireland during the Middle Ages, Creg is now much rarer, giving those who bear this name a unique identity.
The name Creg experienced fluctuating popularity over the years, with peaks in 1968 (12 births), 1970 (16 births), and 1973 (18 births). However, it generally fell out of favor after the 1970s, with only a few instances of more than five births per year since then. Overall, there were 247 babies named Creg born between 1952 and 2004.
