Voronwë

From Tolkien Gateway

Voronwë was a mariner of Gondolin, sent by King Turgon to seek a passage to Aman and call on the Valar for aid against Morgoth. He failed, and was washed ashore in Nevrast, where he encountered Tuor and led him back as messenger of Ulmo to the city of Gondolin. During the Fall of Gondolin he was ordered by Tuor to guard Idril. He escaped the sack, and some accounts say that he sailed with Eärendil on his voyages.

The Gnomish form of his name was Bronweg, who was another character (probably different) in Tolkien's legendarium.
