Elenwë

From the One Wiki to Rule Them All, the Lord of the Rings Encyclopedia.

Elenwë was a Vanyarin elf, the wife of Turgon and the mother of Idril, to whom she passed on the golden hair of her kindred. Her name means "Star" in Quenya.

She died during the crossing of Helcaraxë, while Turgon almost perished himself trying to save her.
