Eylein is in Origin.

Eylein is a contemporary variant of Eileen/Aileen, ultimately tracing to Irish Gaelic Éibhlín, the form adopted after the Normans introduced Aveline to Ireland in the 12th–13th centuries. Aveline itself is a medieval French diminutive of the Germanic Ava, so the core sense often given is “desired” or “lively,” with the hazelnut association a later folk echo from unrelated French aveline. Through English, the line also overlaps with Evelyn/Eveline.

Usage of Éibhlín is embedded in Gaelic tradition - most famously Eibhlín Dubh Ní Chonaill, 18th‑century poet of the lament Caoineadh Airt Uí Laoghaire - while Eileen surged in the Anglophone world during the early to mid‑20th century. Eylein remains rare and modern, aligning with creative respellings such as Eyleen and Eylin. Related variants include Eileen, Aileen, Éibhlín/Eilín, Evelyn/Eveline, and, in Turkish-influenced contexts, Eylin/Aylin carrying the distinct meaning “halo of the moon.”
