§ Of Maeglin The Silmarillion

Yet it is said that Maeglin loved his mother better, and if Eöl were abroad he would sit long beside her and listen to all that she could tell him of her kin and their deeds in Eldamar, and of the might and valour of the princes of the House of Fingolfin. All these things he laid to heart, but most of all that which he heard of Turgon, and that he had no heir; for Elenwë his wife perished in the crossing of the Helcaraxë, and his daughter Idril Celebrindal was his only child.
