Irin is of Irish origin, derived from the Irish name Eirinn, which means "Ireland". It is often used as an alternative spelling to Erin, also of Irish origin, and likewise signifies Ireland or the Irish people. Irin gained popularity in English-speaking countries during the mid-20th century but has since become less common. Despite its decline in usage, it remains a unique and distinctive name choice for those wishing to pay homage to Irish heritage or cultural significance.
"Irin was quite popular in 1971, with five babies sharing this unique name born that year."
