Erinn is a unique and attractive name of Irish origin, derived from the ancient Irish name Éirinn, which means 'Ireland'. It has been traditionally used as a female name in Ireland, but it can also be found among males in some instances. The name gained popularity outside of Ireland in the mid-20th century, likely due to its distinctive sound and connection to Irish heritage.
"Erinn peaked in popularity with 16 newborns in 1970, but it has been more common since the late '80s, especially in 1996 when there were 9 births."
