Boromir: The name 'Boromir' meant 'Faithful Jewel'.
Boromir was the eldest son of Finduilas of Dol Amroth and Denethor II, the Steward of Gondor at the time of The Fellowship. He had a younger brother named Faramir.
He was sent to Lord Elrond in Rivendell for advice after Faramir has a strange dream. He ended up a member of the Fellowship of the Ring.
He carried the Horn of Gondor which had been passed down the line of Stewards since the line began ruling.
He tried to get Frodo to give him the ring, so he could use it against Sauron. It had corrupted him, like it corruted Isildur and so many others.
He was slain by Orcs at Amon Hen near the River Anduin.
Boromir is also the name of at least two other Men in the works of Tolkien.
One being his ancestor, the son of Denethor I, a Steward of Gondor, and the
other the grandfather of Beren.
