Jarran is of English origin, derived from the Old English word 'gyere', meaning 'spear'. It is a variant form of Gerald, which was brought to England by the Normans in the 11th century and was popularized during the Middle Ages. The name Jarran has been used sparingly throughout history but has gained some attention as a unique choice for baby boys in recent years.
"Interesting how the name Jarran appeared 5 times in birth records of 1991, yet remains relatively uncommon overall."
