Our story of Eiley
Ours, offered as ours. Eily appears throughout nineteenth-century Irish writing as the everyday form of Eibhlín — it is the name of the heroine of a much-read novel of 1829 and of several ballads. The long name behind it came into Irish from Norman French and lost its history on the way, which is why nobody can say what it means. Eiley is the modern respelling. What it has is a long and specific Irish literary presence and an origin that ran out several centuries ago.
Meaningnot established
Not established
Eibhlín's origin is disputed. It is generally taken from the Norman French Aveline, whose own root is obscure; a derivation from the Irish word for light has also been offered and is not supported. Eily is its affectionate short form.

The Angell test
Every popular name lives one long story — a climb, a peak, a slow settling back. Eiley's later chapters haven't been written yet, so we borrowed them: Angell climbed just as high around 1970, and its whole arc is on record. Line the two peaks up, and Angell's path sketches the road Eiley is walking now.
