Eile, of Irish origin, means 'sunny'. It is derived from the Old Irish name Eileen, which itself evolved from the Gaelic word 'eibhlin', meaning 'vigor' or 'life'. This unique moniker was popularized by the 19th-century Irish poet and playwright, George Fitzmaurice's poem 'Eileen Aroon'. Today, it is recognized as a distinct name in its own right.
The name Eile saw a notable gap in usage between 2019 and 2023, with five births recorded each year.
