§ Of the Voyage of Eärendil and the War of Wrath The Silmarillion

Yet not all the Eldalië were willing to forsake the Hither Lands where they had long suffered and long dwelt; and some lingered many an age in Middle-earth. Among those were Círdan the Shipwright, and Celeborn of Doriath, with Galadriel his wife, who alone remained of those who led the Noldor to exile in Beleriand. In Middle-earth dwelt also Gil-galad the High King, and with him was Elrond Half-elven, who chose, as was granted to him, to be numbered among the Eldar; but Elros his brother chose to abide with Men. And from these brethren alone has come among Men the blood of the Firstborn and a strain of the spirits divine that were before Arda; for they were the sons of Elwing, Dior's daughter, Lúthien's son, child of Thingol and Melian; and Eärendil their father was the son of Idril Celebrindal, Turgon's daughter of Gondolin.
