Earendil

The son of Tuor and Idril (daughter of Turgon) escaped the sack of Gondolin to marry Elwing (daughter of Dior, who was the son of Beren and Luthien). With the aid of one of the Silmarils given to him by Elwing, he sailed to Aman to plead with the Valar for aid against Morgoth. Manwe found sympathy, and gathered the Ainur for a last march into Endor to cast down the Black Enemy. In the end, Earendil was sentenced to forever ride in a great ship across the sky, the Silmaril bound on his brow. For the War of Wrath he came down to do battle with the Dragons of Thangorodrim and slew Ancalagon, lord of the Winged Drakes. His line continued in the persons of Elrond and Elros.
