Eileen

Eileen is an English rendering of Irish Eibhlín, a name connected with the Aveline and Evelyn family. Its deeper origin is uncertain, and it has also become associated with Helen in naming use. That overlap explains why lists offer different meanings, but desired, island, and light should not all be treated as certain translations of Eileen.

Aileen is a close spelling comparison, while Eibhlín preserves the Irish form. In a familiar English reading, Eileen begins with an eye sound and has two syllables. A family honoring an Irish relative may prefer the exact inherited spelling, even when another form would sound much the same aloud.
