Origin of the baby name Erin
Erin is an Anglicised form of Eirinn, the dative singular and dialectal nominative form of Eire, the Irish-language name for Ireland. The ultimate origin of Eire is connected to the Proto-Celtic goddess name Eriu, one of the mythological queens of Ireland from whom the island takes its name in Gaelic tradition. When English speakers began using Erin as a personal name, they were borrowing the ancient poetic name for Ireland and turning it into a given name with all of that heritage behind it.
