Ingwion
From Tolkien Gateway
Ingwion was the son of Ingwë and a cousin of Indis, the wife of Finwë.
History
Ingwion led the armed Host of the Vanyar to the Middle-earth and the War of Wrath that overthrew Morgoth at the end of the First Age.
Ingwion was the captain of the force that landed and captured the haven of Eglarest in the first battle of the war. He presumably still lives with his father upon Taniquetil.
Etymology
Ingwion literally means the "son of Ingwë".
Note
His name was changed from Ingwiel to Ingwion in the course of the writing.
