Originating from Greek roots, the name Gregorios is derived from the word 'Gregorios,' which means 'vigilant' or 'watchful.' It is a variation of the Latin name Gregorius, itself stemming from the Greek 'Gregorios.' This name has been traditionally associated with the Christian religion due to several prominent figures bearing this name, such as Pope Gregory I and Saint Gregory of Nazianzus. Throughout history, Gregorios has been popular among Eastern Orthodox Christians, particularly in Greece, Cyprus, and other countries with a significant Eastern Orthodox population.
"Gregorios was a popular baby boy name in 1977 with five newborns bearing this name."
